J.E. Rehler, plaintiff-appellant in this Texas diversity suit to recover for the wrongful death of James A. Rehler, appeals the district court's judgment on the jury's verdict in favor of the defendant-appellee, Beech Aircraft Corporation. Appellant asserts that the district court committed reversible error by refusing to submit certain requested issues and instructions to the jury, and that the jury finding of pilot negligence is not supported by sufficient evidence. Finding that the matters complained of do not present reversible error, we affirm.

In this suit, J.E. Rehler, sought to recover for the wrongful death of his father, James A. Rehler ("Rehler"), who died when the Beech Baron, model 95-B55, aircraft he was piloting crashed outside Jarrell, Texas, on March 21, 1979. Rehler's Baron, a light, twin-engine airplane, was manufactured by defendant-appellee, Beech Aircraft Corporation, in 1974. The Federal Aviation Administration's ("FAA") aircraft registration file indicates that the aircraft was given an airworthiness certificate on July 7, 1974,1 and was initially sold by Beech to Chaparral Aviation on July 18, 1974. The airplane subsequently was sold a number of times, and ultimately was purchased by the decedent2 from Gantt Aviation in Georgetown, Texas, on August 25, 1978, approximately seven months before the accident.

Rehler departed from Georgetown Municipal Airport in his airplane on the afternoon of the fatal accident, March 21, 1979. Approximately one hour after Rehler took the Baron into the air, three bystanders observed that the plane was spinning to the left. One of the witnesses testified at trial that the airplane was at a low altitude prior to the spin, and further indicated in a statement to the National Transportation Safety Board ("NTSB"), subsequently admitted as an exhibit, that the airplane's "nose [was] pitched down." The Baron subsequently crashed, killing Rehler. The witnesses were unable to see the airplane hit the ground, since the site was obscured by trees; as a result, they were unable to testify whether the nose of the airplane faced up or down at the time of impact. The plane crashed nine miles north of its point of takeoff.

The NTSB, the federal agency responsible for investigating all fatal aircraft accidents in the United States, investigated Rehler's death. The parties stipulated that "[a]n examination of the aircraft by the NTSB following the accident failed to reveal any malfunctioning parts or any mechanical reason which would have precluded normal operation of the aircraft prior to impact." The parties also agreed that "[n]o turbulence was reported" on the afternoon of the accident and that Rehler had visability of twenty miles. Moreover, the parties stipulated that in an autopsy and toxicological study performed on the decedent, "[n]o evidence was found to indicate pilot incapacitation or impairment to operate an aircraft."

The plaintiff-appellant, J.E. Rehler, independent executor of the Estate of James A. Rehler, brought this wrongful death action on behalf of the decedent's estate and heirs. The case was tried to a jury. Under a products liability theory,3 the plaintiff alleged that Beech was liable for defective design of the Baron and for failure to adequately warn consumers that the aircraft had a tendency to enter into a flat spin. Under a misrepresentation theory,4 he alleged that Beech had falsely represented that the spin recovery procedure contained in the Pilot's Operating Handbook and FAA Approved Airplane Flight Manual ("Pilot's Operating Handbook") would correct a flat spin, that the aircraft had been properly tested for undue spinning tendencies, and that the Baron did not have undue spinning tendencies.5 In addition to compensatory damages he sought exemplary damages on the ground that the defendant had shown a conscious indifference to the safety of persons flying the Baron. The jury subsequently returned a special verdict finding that there was no defective design of the aircraft, nor any failure by Beech to give adequate warnings and instructions for its safe use, which was a producing cause of the accident, and that pilot negligence was a producing cause of the accident, accounting for 100 percent of the causation.6 The district court entered judgment for Beech on the jury verdict.

On appeal, J.E. Rehler argues that the district court erred by refusing to submit to the jury issues concerning whether Beech made misrepresentations respecting its testing of the Baron's undue spinning tendencies, the presence of undue spinning tendencies, the effectiveness of the spin recovery procedure outlined in its Pilot's Operating Handbook, and whether Beech had shown conscious indifference to the safety of those who would fly in the Baron model. Appellant also argues that the district court erred by refusing to give certain requested instructions which appellant contends were necessary for the jury to adequately understand the issues. Appellant's final contention respecting liability is that the evidence is insufficient to support the jury's finding of pilot negligence. We address these asserted grounds for reversal in turn.

Appellant argues that the district court erred by refusing to submit to the jury the issue whether Beech misrepresented to Rehler that the spin recovery procedure outlined in the Pilot's Operating Handbook would bring the airplane out of "any" spin the airplane might enter into, when in fact the procedure would not correct a flat spin. He argues that this alleged misrepresentation is actionable under section 402B of the Restatement (Second) of Torts. In response, Beech argues, inter alia, that the district court did submit this issue to the jury. We agree with appellee that the district court's charge and the form of the first interrogatory encompass Rehler's misrepresentation theory as it pertains to any representation in the Pilot's Operating Handbook.

The Pilot's Operating Handbook for the Beech Baron stated:

"SPINS

"If a spin is entered inadvertently:

"Immediately move the control column full forward, apply full rudder opposite to the direction of the spin and reduce power on both engines to idle. These three actions should be done as near simultaneously as possible; then continue to hold this control position until rotation stops and then neutralize all controls and execute a smooth pullout. Ailerons should be neutral during recovery.

"NOTE

"Federal Aviation Administration Regulations did not require spin demonstration of airplanes of this weight; therefore, no spin tests have been conducted. The recovery technique is based on the best available information."7

Appellant argues that the manual failed to distinguish between flat spins and steep (normal) spins, since the manual obliquely states that the procedure is applicable "[i]f a spin is entered." He argues that while the procedure might effect a recovery from a steep or normal spin, the procedure has been shown to be ineffective in correcting a flat spin. By suggesting falsely that the procedure will correct "any" spin, Rehler argues, the passage in Beech's manual constituted a misrepresentation actionable under section 402B.

Our understanding is that the Texas law of section 402B covers only affirmative or express misrepresentations.8 Even if Texas courts were to extend section 402B's coverage to implied misrepresentations, however, we find that the charge and the form of the interrogatory were sufficient to cover any express or implied misrepresentations in this respect that might reasonably have been found in the Pilot's Operating Handbook. The first interrogatory which the district court submitted to the jury asked, "Which of the following [factors], if any, do you find from a preponderance of the evidence was a producing cause of the accident in question, and what percentage of the total causation was attributable to each?" Among the factors listed was the "[f]ailure of Beech to give adequate warnings and instructions for the safe use of the aircraft." The district court provided the following definition to the jurors:

" 'Adequate warnings and instructions' means warnings and instructions sufficient to convey to the reasonably prudent pilot the nature and extent of the dangers involved in the use of the aircraft and how to avoid the dangers."

We find that the interrogatory and charge were phrased in such a way that if the jury believed that the Pilot's Operating Handbook contained an express or implied false representation to the effect that the spin recovery procedure would correct a flat spin, the jury would have had to conclude that Beech had failed to give "adequate ... instructions" and warnings. The jury could not find that a spin recovery procedure which does not work and which, when followed, resulted in "physical harm to ... consumer[s]" constituted an "adequate" instruction. Conversely, in order for the jurors to have decided that the instructions in the manual were adequate, it seems clear that they would have had to conclude that the manual's spin recovery instructions did not contain "a misrepresentation of a material fact concerning the character" of the airplane which resulted in "physical harm to a consumer" because of his reliance on that misrepresentation. Restatement (Second) of Torts Sec. 402B (emphasis added); Crocker v. Winthrop Laboratories, 514 S.W.2d 429, 431 (Tex.1974) (Reavley, J.) (quoting section 402B in context of Texas law). However the jury answered the first interrogatory, it would by necessity also answer the question whether or not the Pilot's Operating Handbook contained an express or implied misrepresentation. Therefore, we find that the district court adequately submitted the issue of misrepresentation in the Pilot's Operating Handbook in the first special interrogatory.

Since the district court's first interrogatory covered appellant's section 402B misrepresentation theory, as it pertains to the Pilot's Operating Handbook, we reject appellant's argument that the district court erred by failing to submit the issue to the jury. See Fleming v. Michigan Mut. Liab. Co., 363 F.2d 186, 189 (5th Cir.1966) ("It is a fundamental rule that a trial court is not required to give every charge requested or to instruct the jury in the particular manner or form requested by the parties, even though such instructions state correct principles of law, if the subject matter of such requested special instructions was sufficiently covered by other instructions from the court." (Emphasis added.)); Hussein v. Isthmian Lines, Inc., 405 F.2d 946, 949 (5th Cir.1968) (noting that trial court correctly declined requested instruction where the "substance of the requested instruction was covered in the judge's charge"); Freimanis v. Sea Land Serv., Inc., 654 F.2d 1155, 1163 (5th Cir.1981) (" 'if the requested instruction is given "in substance," there is no error.' " (quoting Beard v. Mitchell, 604 F.2d 485, 497 (2d Cir.1979)). The jury's finding that no failure of Beech to give adequate warnings and instructions for the safe use of the airplane contributed to the accident has resolved that misrepresentation issue against appellant.9

Prior to the type certification of the Baron model in 1963, Beech performed a test flight in the aircraft. Among the characteristics Beech tested for was undue spinning tendencies, as required by Civil Air Regulation 3.123.10 The Beech engineering test pilots, following the specific procedure outlined in that regulation, determined that the Baron satisfied the Civil Air Regulations. Beech transmitted test results on this and other characteristics to the FAA, which subsequently type certified the model.

At trial, appellant introduced evidence which suggested that the Baron demonstrated undue spinning tendencies following a single-engine stall. Appellant argues that the jury could have concluded from this evidence that Beech was intentionally deceptive in its test flights and certification of the Baron. Therefore, J.E. Rehler argues that the district court erred by refusing to submit to the jury the issues whether Beech misrepresented to the FAA (and consequently to the public) that the aircraft had been properly tested for undue spinning tendencies, when in fact it had not, and that the aircraft did not have an undue tendency to spin, when it actually did display such a tendency. Restatement (Second) of Torts Sec. 402B. Finding no substantial evidence to indicate that Beech misrepresented anything concerning the Baron's alleged undue spinning tendencies or its testing of this supposed characteristic, we affirm the district court.

Appellant introduced into evidence a report compiled by United States Army Test Pilot Major Horton and Army Flight Test Engineer Paul Bonin. These two were commissioned by the Army in 1973 to test the Army version of the Baron. The report disclosed the results of these tests, particularly as to the Baron's single-engine characteristics. Bonin testified that prior to their test flights, he and Major Horton "determined the test conditions that [they] ... would test, the test procedure." William P. Kelly, an expert witness for appellant, testified that Horton and Bonin's "methods probably went--and I am sure it went--beyond what is called for in the FAA certification." (Emphasis added.) The Army test flights were filmed by a chase plane. Based on characteristics the Baron displayed during these tests, Horton and Bonin compiled a report which suggested that the Baron had undue spinning tendencies.

Appellant's argument is that the jury could conclude from the "Horton" report and the chase pilot film that Beech had intentionally misreported the results of its single-engine stall test or otherwise deceived the FAA and consequently the public.11 Phrased in terms of section 402B, appellant alleges that Beech had represented that FAA type certification had been achieved by following the normal and proper certification procedures when in fact it had been achieved by falsifying the test results. While appellant's evidence provided a basis from which the jury could have concluded that the tests required by the FAA in the Civil Air Regulations were not thorough enough to reveal the aircraft's undue spinning tendencies,12 we find no substantial evidence to indicate that Beech failed to follow the FAA procedures or misreported the results of the Civil Air Regulations test.

As noted above, appellant's own expert, Kelly, stated that he was certain that the Army tests went beyond the procedures required for type certification. Kelly added that the Army testers consequently would be expected to see a more severe reaction of the plane to a single-engine stall than would a pilot following the Civil Air Regulations procedure. Another one of appellant's own experts, Dr. Andrew Craig, affirmatively expressed the view that Beech had correctly followed the Civil Air Regulations and correctly reported the results of those tests. Craig responded to cross-examination:

"Q. [Y]ou are not saying that Beech's tests were misrepresented to the government in any way.

"A. That is correct.

"....

"Q. Now, do you have any opinion that the Beech pilot, test pilot falsely reported the results of his tests?

"A. To the contrary.

"Q. You believe that he truly reported it.

"A. Yes.

"Q. And that in fact he got what he was supposed to get, isn't that correct, insofar as the FAA was concerned?

"A. Yes.

"Q. Now, that regulation with respect to the undue spinning tendency, that is the only place in the regulation that it appears, is in that one particular provision about the single engine operation, isn't that correct?

"A. Yes.

"Q. And it doesn't just say 'determined that there was no undue spinning tendency.'

"A. No.

"Q. It sets out some specific test parameters, is that correct?

"A. Yes.

"Q. You have no reason to believe that the Beech test pilot didn't follow those specific test parameters.

"A. That's right."

Dr. Craig went on to affirm that the Army testers did not "follow those specific test parameters" set out by the FAA and in fact "far exceeded what the FAA requires to be done to determine if there is undue spinning tendencies." (Emphasis added.) Craig added that the Army's "intent was quite different from the certification flight test" and that that was the reason "why they got two different answers" to the question whether the Baron had undue spinning tendencies. Later during cross-examination, Craig acknowledged that subsequent to the type certification of the Baron, the FAA and Beech participated in a joint test program to "revalidate the findings of compliance with the Civil Air Regulations." Craig agreed

"that the FAA found the results were satisfactory, that it was concluded that as required by the applicable regulations no undue spinning tendency existed." (Emphasis added.)13 We conclude that there is no substantial evidence supporting appellant's contention that Beech misrepresented that it had followed the procedure outlined in the Civil Air Regulations and had found no undue spinning tendencies during the course of that test. The fact that the Army, using an entirely different and more thorough and rigorous test regimen, discovered undue spinning tendencies, does not adequately support an inference that Beech failed to follow the FAA regulations or falsified the test results. Moreover, appellant's own expert opined that Beech did correctly follow the regulations and correctly reported the test flight results. Therefore, we find that the district court properly refused to submit a section 402B issue to the jury concerning any misrepresentation that Beech followed the procedure outlined in the Civil Air Regulations and that the Baron did not display undue spinning tendencies as that term is operationally defined in Regulation 3.123. See Freimanis v. Sea-Land Serv., Inc., 654 F.2d at 1163 (noting that a " 'plaintiff has no right to the presentation of an instruction unsupported by the evidence adduced at trial' " (quoting Beard v. Mitchell, 604 F.2d at 497.)

Instructions Concerning Section 402A Liability

Appellant argues that the district court erred by refusing to adequately charge the jury concerning Beech's duties and liability under section 402A of the Restatement (Second) of Torts.14 He argues that the district court instructed the jurors on the products liability theory only in general terms rather than in a way calculated to "guide, direct, and assist them toward an intelligent understanding of the legal and factual issues." In particular, appellant argues that the district court erred by refusing to specifically instruct the jury that a product can be found defective even without proof of a specific defect, that the FAA's Civil Air Regulations are merely minimum standards for airworthiness and do not constitute a defense under section 402A, that the manufacturer has a continuing duty to remedy a defect or provide adequate warnings and instructions, and that the manufacturer's warnings must be sufficiently detailed to apprise the consumer of the nature and extent of the danger which use of the product entails.15 Beech argues, in turn, that the instructions considered as a whole were adequate and that certain of appellant's requested instructions were wrong as a matter of law.

On appeal, our concern is not whether the charge was faultless in every particular but whether the jury was misled in any way and whether the instructions furnished the jury an adequate understanding of the issues and its duty to determine them. Robert v. Conti Carriers & Terminals, Inc., 692 F.2d 22, 24 (5th Cir.1982); Wright v. Wagner, 641 F.2d 239, 242 n. 4 (5th Cir.1981); Chemetron Corp. v. Business Funds, Inc., 682 F.2d 1149, 1178 (5th Cir.1982), cert. denied sub nom. Bintliff v. Chemetron Corp., 460 U.S. 1007, 103 S. Ct. 1254, 75 L. Ed. 2d 476 (1983); Smith v. Borg-Warner Corp., 626 F.2d 384, 386 (5th Cir.1980). "A party is entitled to reversal for a district court's failure to give a particularly requested instruction only if the jury was misled by the instructions that were actually given. The court is under no obligation to couch the charge in terms requested by counsel." Wyatt v. Penrod Drilling Co., 735 F.2d 951, 955 (5th Cir.1984); Pierce v. Ramsey Winch Co., 753 F.2d 416, 425 (5th Cir.1985) (quoting Wyatt ). Considering appellant's arguments in light of this standard, we find that they present no reversible error.

Appellant notes that while substantial evidence concerning the Baron's tendency to enter into a flat spin was introduced at trial, no proof could be offered that pinpointed the specific flaw or flaws in the design of the aircraft which created this dangerous characteristic. He argues that the district court should have instructed the jury that proof of the defect could be made by circumstantial evidence and that the Baron could be found defective and unreasonably dangerous even though no specific defect was established.16 Absent this instruction, he contends, the jury could have concluded that appellant failed to meet his burden of proof of establishing that the airplane was a defective product.

Appellant is correct in arguing that for a product to be found defective it is not always necessary that there be proof of a specific, particular underlying defect. General Motors Corp. v. Hopkins, 548 S.W.2d 344, 349-50 (Tex.1977) (Reavley, J.) ("If the plaintiff has no evidence of a specific defect in the design or manufacture of the product, he may offer evidence of its malfunction as circumstantial proof of the product's defect."). However, we are unable to conclude that the district court's failure to expressly and specifically instruct the jury that appellant only needed to prove that the product as a whole was defective, and that he did not need to prove the existence of a particular defect, misled or inadequately guided the jury in this respect. Nothing in the charge even suggests that a specific or particular defect had to be shown. To the contrary, under the first interrogatory the jury was asked whether "[d]efective design of the aircraft " was a "producing cause of the accident in question." The interrogatory correctly required the jury to consider only whether the aircraft had been shown to be defectively designed, not whether any specific or particular defect in it had been identified and proven. And, the jurors were also instructed that they "may make deductions and reach conclusions which reason and common sense lead you to draw from the facts established by the testimony and evidence in the case." It does not appear that "the jury was misled by the instructions that were actually given." Wyatt, 735 F.2d at 955.

Moreover, the charge correctly states the Texas substantive law. The jurors in the instant case were instructed by the district court that " '[d]efective design' of a product is a design of a product that renders the product unreasonably dangerous taking into consideration the utility of the product and the risk involved in its use." This charge is almost verbatim with the language of Texas Pattern Jury Charges, which states:

"Design Defect

"A 'defectively designed' product is a product that is unreasonably dangerous as designed, taking into consideration the utility of the product and the risk involved in its use." 3 Texas Pattern Jury Charges, PJC 71.02, at 217 (1982).

The Supreme Court of Texas, discussing "Volume III of the Texas Pattern Jury Charges (1982)," has stated,

"We explicitly approve the Pattern Jury Charges issue and instruction for design defect cases, and disapprove the addition of any other instructions in such cases, however correctly they may state the law under Sec. 402A of the Restatement (Second) of Torts." Acord v. General Motors Corp., 669 S.W.2d 111, 116 (Tex.1984).

The district court's decision whether to use form or pattern instructions is governed under federal law, since it involves the manner and method of instructing the jury as opposed to the substance of the instruction.17 However, the issue of what constitutes a "defectively designed" product is a matter of substantive state law. The Acord court, by applying its imprimatur to the statement of law contained in Texas Pattern Jury Charges, has approved the definition of "defectively designed" product which the district court used in its charge. We do not believe that the district court's instruction, which tracks the language of the court-approved pattern jury charges, constitutes reversible error simply because it did not go into the detail which appellant urged. "The trial judge is not required to give a flawless instruction suitable for publication in a treatise." Robert, 692 F.2d at 24. Finding no reason to believe that the jury was in some way misled or lacked a sufficient understanding of the issue, we hold that appellant's complaint in this respect presents no reversible error. Id.; Wright, 641 F.2d at 242 n. 4; Chemetron, 682 F.2d at 1178.

Appellant notes that Beech emphasized at trial that the FAA's 1956 Civil Air Regulations, which established the certification standards applicable at the time the Baron was flight tested, did not require the company to spin test the Baron. Appellant argues that the jury accordingly should have been instructed that the Civil Air Regulations are merely a minimum standard for airworthiness, and that compliance with the regulations is not a defense to a section 402A action but rather is only one of the elements the jury may consider in determining whether the Baron was defective in an unreasonably dangerous way.18 Because the court omitted this instruction, appellant contends, "the jury could have concluded that Beech was under no duty to spin test the Baron" and that mere compliance with FAA regulations precluded a finding that Beech was liable for the crash.

We are unable to conclude that the jury was likely misled into believing that mere compliance with the FAA regulations constituted a defense to a section 402A action. Nothing in the court's charge so suggested. Counsel for appellant told the jury during his summation that it could find that the airplane was defective even if Beech had complied with the FAA standards. Beech's counsel did not dispute this argument. Appellant's counsel told jurors during closing argument:

"They didn't spin test it either. They say: 'Oh, well, we didn't have to. The FAA didn't make us. Besides, it's too dangerous for our test pilots to do it.'

"Think about that one for a while. It seems like to me that is all the more reason they ought to have done it if it is that dangerous. They tested other planes. They tested their Travel Air and they tested the Duchess, six turns. The FAA didn't make them do that. No requirement to do that. It is certified under the same regulations. It is placarded; no spins, no requirement, and yet they did it. The[y] spun it six times.... Did they do it on the Baron? Did they go back and say look at all these people that are being killed in these flat spins. Maybe we ought to go back and test this Baron with a model of this or that or whatever it takes to do it and see if we can't find out what is wrong with it and see if we can't correct it and see if we can't do what Piper did? Oh, no, to heck with the people out there already flying them. What we want to do, we are concerned about the ones we haven't sold yet. We are going to test it (emphasis in original transcript) and they did.

"Then they want to stand here and say, 'well, we didn't know how to test the Baron, we couldn't do it and nobody made us and everything else.' I submit to you that they could but they didn't because they are more concerned with selling airplanes than they were the safe use of those they had already sold. Otherwise, there is no justification for not trying to do something with the Baron that they had built and sold when they didn't know what its spin characteristics were ....

"....

"... I think it ought to be pretty apparent the FAA is not going to force them to do anything. You may be able to with your verdict.

"By your verdict, you call tell Beech that the people in San Antonio don't like this kind of corporate irresponsibility or immorality or whatever you want to call it." (Emphasis added.)

We find no indication in the record that Beech ever suggested to the jury that Beech's compliance with FAA regulations, of itself, precluded the jury from finding that the airplane was defective in an unreasonably dangerous way. In light of appellant's uncontradicted argument that the jury could find that the plane was defective in spite of compliance with the FAA, the lack of any contrary suggestion in either the charge or appellee's presentation, and the fact that the charge defined defective design in terms of unreasonable dangerousness, considering risk and utility, without any reference to regulatory compliance, we find no basis from which the jury could have reached the conclusion that such compliance alone was a defense. See Freimanis, 654 F.2d at 1163-64 (" '[T]he refusal [of an instruction] will not be reversible if the party's theory of the case was apparent throughout the course of the trial'.... [T]he appellant's theory of the case was apparent throughout the trial and in the appellant's closing argument. The jury could not have misunderstood either the law or the appellant's theory...." (Emphasis added.)). See also McNeese v. Reading and Bates Drilling Co., 749 F.2d 270, 274 (5th Cir.1985) (instructions to be assessed in consideration of "the pleadings, evidence and argument of counsel"); Alexander v. Conveyors & Dumpers, Inc., 731 F.2d 1221, 1227 (5th Cir.1984) (failure to give requested instructions detailing factors to be taken into account in determining assumption of risk not error where "[c]ounsel had the opportunity to emphasize the matters in his favor contained in these proposed instructions during jury argument"). Therefore, we find that the omission of the requested instruction did not constitute reversible error.19

Appellant also argues that the district court should have instructed the jury that Beech was under a continuing duty to warn of or remedy dangers that came to the company's attention after the product had been sold.20 He argues that without this instruction, the jury may have judged the adequacy of Beech's warnings and instructions in light of the company's knowledge at the time the airplane was first sold. If the jury had been instructed concerning the continuing duty to warn, he argues, "it could have determined that based upon the knowledge Beech gathered after its product was sold, the warning in the manual was inadequate." (Emphasis added.)

We do not believe the district court's failure to charge the jury concerning Beech's continuing duty to warn of or remedy dangerous defects misled the jury into believing that it could consider Beech's knowledge only up through the time the company sold the airplane. The first interrogatory asked the jury to determine whether the "[f]ailure of Beech to give adequate warnings and instructions for the safe use of the aircraft" was a "producing cause of the accident in question." The interrogatory contained no express or implied limitation as to time. Its natural, as well as its literal, meaning permits of no such limitation. Similarly, the charge's definition of adequate warnings and instructions was in no way related either to the manufacturer's knowledge or the state of the art. Moreover, the jury heard evidence from both sides on developments which occurred after the sale of this particular airplane and before Rehler's accident and which pertained to Beech's notice of accidents and its efforts to provide updated instructions. Appellant was permitted to introduce evidence concerning eleven accidents allegedly involving flat spins and all occurring after the sale of the Baron and prior to Rehler's death.21 In connection with this evidence, appellant argued that Beech had knowledge of these accidents and yet still failed to test for or alleviate the undue spinning tendencies of the Baron, or warn consumers about this characteristic or how to recover from a spin. Beech itself presented Wayne Phillip Hunt, the manager of the Commercial Publications section of Beech, who testified that Beech mailed out a completely "re-formated version of the existing [pilot's operating] manual" plus a safety information booklet to the owners of record of its airplanes, free of charge, on August 3, 1978; the mailout occurred after Beech's initial sale of this particular airplane in July 1974 but before Rehler's fatal crash in March 1979. This revised Pilot's Operating Handbook contained the warning that the Baron had not been spin tested and that the recovery procedure was based only on secondary information. The updated Pilot's Operating Handbook was introduced into evidence.22

We conclude that the jury could not have misinterpreted the instructions so as to believe that the adequacy of Beech's warnings and instructions was to be judged against Beech's actual or imputed knowledge up to but not beyond the time the airplane was first sold. See Freimanis, 654 F.2d at 1163-64.

Appellant also contends that the district court erred by refusing to instruct the jury that a manufacturer may not rely on other parties to warn of the dangers in its product, but must itself support an adequate warning; that the manufacturer must warn of dangers that may arise from foreseeable misuse or mishandling of a product; that the warning must specifically set forth the nature of the particular dangers involved; and that the degree of warning required of the manufacturer depends on the magnitude of danger that its product involves.23 Beech replies that the definition of "adequate warnings and instructions" which the district court submitted to the jury tracks the language of the approved Texas Pattern Jury Charges, and correctly states Texas substantive law. It further argues that the instructions requested by appellant would not have significantly added to the jury's understanding of the issues involved in this case. We hold that the instructions, in the respects complained of, were neither incorrect nor inadequate, and that appellant's contentions present no reversible error.

The "Comment" to 3 Texas Pattern Jury Charges PJC 71.04 (1982) states:

"[T]he Committee [on Pattern Jury Charges] has prepared the following instructions:

" 'Adequate warnings and instructions' means warnings and instructions that are given in such form that they could reasonably be expected to catch the attention of the reasonably prudent person in the circumstances of its use; and the content of the warnings and instructions must be of such a nature as to be comprehensible to the average user and to convey a fair indication of the nature and extent of the danger and how to avoid it to the mind of a reasonably prudent person." PJC 71.04 at 238.

The district court tracked the language of the pattern charge, instructing the jury as follows:

" 'Adequate warnings and instructions' means warnings and instructions sufficient to convey to the reasonably prudent pilot the nature and extent of the dangers involved in the use of the aircraft and how to avoid the dangers."

As noted above, the Supreme Court of Texas has approved the pattern instructions contained in Texas Pattern Jury Charges as a correct statement of the state's substantive law. Acord, 669 S.W.2d at 116. Therefore, the instruction "actually given" accurately states Texas law concerning the definition of "adequate warnings and instructions." Wyatt, 735 F.2d at 955.

We reject appellant's arguments that the district court's failure to provide additional instructions misled the jury. Respecting the complaint that the jury was not told that the manufacturer must itself provide an adequate warning, rather than relying on third parties to do so, we observe that the first interrogatory asks only whether the "[f]ailure of Beech to give adequate warnings and instructions for the safe use of the aircraft" was "a producing cause of the accident in question."24 (Emphasis added.) The interrogatory frames the issue in terms of adequate warnings by Beech, rather than in terms of whether the decedent had received adequate warnings and instructions from whatever source or sources. Adequate warnings were defined as those "sufficient to convey" the nature and extent of the dangers and how to avoid them. In sum, the jury was asked if Beech's warnings and instructions were not "sufficient to convey" the nature and extent of the dangers and how to avoid them, and if any such deficiency in Beech's warnings and instructions was a producing cause of the accident. There was no mention of third-party warnings, actual or potential. The charge is neither prejudicially misleading nor inadequate in the respect complained of.

Appellant contends that the jury should have been instructed that the thoroughness of the required warning depends on the extent of the dangers posed and that the warning must specify the particular dangers involved. However, the jury was told that for a warning to be adequate it had to be "sufficient to convey" both the "nature " and "extent " of the "dangers" involved; instructions had to sufficiently convey "how to avoid the dangers." This adequately encompasses the several concepts urged by appellant in this connection so that the charge presents no reversible error in respect thereto.

It is further claimed that the instructions were deficient in failing to state that the duty to warn extended to dangers that might arise from foreseeable misuse or mishandling. However, the form of submission plainly reflected that causative pilot negligence was in no sense inconsistent with causative inadequate warnings or instructions--it clearly shows that the jury is authorized to find the latter even though it concludes that the former represented the preponderant reason for the crash. Moreover, the instructions given placed no "misuse" or similar limitations on the character of "the dangers involved in the use of the aircraft" which must be warned against. While the type of warning of those dangers was geared to what was "sufficient to convey" them "to the reasonably prudent pilot," this was a proper statement of the law. As we said in Pavlides v. Galveston Yacht Basin, Inc., 727 F.2d 330, 338-39 (5th Cir.1984):25

"Since the warning is intended to be adequate for the 'average user' of the product, the adequacy of the warning must be evaluated together with the knowledge of the ultimate users of the product. Where, for example, a product is marketed solely to professionals experienced in using the product, the manufacturer may rely on the knowledge which a reasonable professional would apply in using the product. See Martinez [v. Dixie Carriers, Inc.], 529 F.2d at 465-67 [5th Cir.1976] .... Where, however, the product is marketed to the general public, the manufacturer must tailor the warning to the man-in-the-street, Borel [v. Fiberboard Paper Products Corp.], 493 F.2d [1076] at 1092-93 [cert. denied, 419 U.S. 869, 95 S. Ct. 127, 42 L. Ed. 2d 107 (1974) ] ...." (Emphasis added.)

The instructions were neither incorrect nor prejudicially incomplete or misleading in the respect complained of. We also observe that appellant argued to the jury, without objection, his theories in this regard,26 and that Beech did not argue that warnings and instructions did not have to address dangers posed by foreseeable pilot error. We find no reversible error in regard to this asserted deficiency in the charge.

Appellant asserts the evidence is insufficient to support the jury's finding that decedent was negligent in the operation of his airplane. Although we are inclined to believe that the evidence is not insufficient in this respect, we find it unnecessary to reach that question. The judgment for Beech is required by the jury's "We do not" answers to parts a and b of the first interrogatory, establishing that no defective design of the aircraft was a producing cause of the accident and that no failure of Beech to give adequate warnings and instructions was a producing cause. These answers are independent of any finding as to the presence or absence of pilot negligence.27 Appellant did not object to the submission of part c, inquiring of pilot negligence, of the first interrogatory.28 Even if the jury had answered "We do not" to part c, thus finding no pilot negligence, as appellant contends it should have, nevertheless Beech would still be entitled to judgment on the verdict. See Neubauer v. City of McAllen, 766 F.2d 1567, 1577 & n. 10 (5th Cir.1985). Under these circumstances, it is unnecessary to reach appellant's contention that there is no evidence of pilot negligence.29CONCLUSION

For the foregoing reasons, the judgment below is affirmed.

AFFIRMED.
