judgment entered by the District Court1 in favor of appellee Anchor Longwall and

Rebuild, Inc. (Anchor). Appellants contend the District Court erred in its May 3, 2007

final order excluding appellants’ expert witness’ testimony. Appellants also challenge the

District Court’s grant of Anchor’s motion for partial summary judgment dismissing

appellants’ claims for strict liability against Anchor under Restatement (Second) of Torts

§ 402A. Finally, appellants challenge the District Court’s sua sponte grant of summary

judgment in favor of third-party defendant System Stecko as to Anchor’s claim of

contribution against Stecko. For the following reasons, we will affirm the District

Court’s orders.

                                                  I.

       Because we write only for the parties, our factual summary is brief. Appellants

filed a civil complaint on November 29, 2002, asserting claims against appellee Anchor

for strict liability, negligence, breach of warranty, emotional distress and loss of

consortium for Meadows’ injuries that occurred while pressurizing a mine shield against

the roof of the Maple Creek Mines where he was employed. Appellants allege that a

shut-off valve fitting replaced by Anchor during a refurbishing project malfunctioned,

pulled loose from the valve assembly housing due to the pressure of the hydraulic fluid,

and struck Meadows on the right side of his face. As a result of the accident, Meadows

                                              3
lost use of his right eye.

       The accident occurred on December 6, 2000 while Meadows was installing 800-

ton longwall shields originally manufactured and designed by Meco-Dowty in the Mine.

Meadows was employed by the Mine as a longwall helper/longwall utility man.

Longwall shields are placed in succession and after each shield is in place its leg jacks

(hydraulic lift cylinders) are pressurized to raise the canopy of the shield to the mine roof.

Meadows was engaged in manually pressurizing a shield, likely the shield known as

Longwall International 045 (Shield # 45), which required him to stand close to the

hydraulic system when a shut-off valve fitting pulled loose from the valve assembly

housing and struck him in the face.

       Shortly before the accident, the Mine contracted with Montgomery Equipment

Company to repair approximately 189 of its longwall shields. Montgomery subcontracted

with several repair companies, including Anchor, to refurbish and/or repair the shields.

Anchor repaired 39 of the 189 longwall shields repaired for the Mine, including Shield #

45, which discovery revealed was likely the shield on which Meadows was working at the

time of his accident. As part of the repair and refurbishment project, Anchor replaced

hoses and valves and installed new hose kits, including Stecko valves of a type that

Meadows alleges caused his injury. Anchor’s paperwork revealed that Shield # 45 was

missing a base lift jack at the time it was received and that the Mine elected not to replace

it.



                                              4
       Appellants hired Mark A. Sokalski, P.E., to investigate the cause of the valve

malfunction and testify as an expert witness as to liability and causation. Sokalski

testified in his deposition that the accident occurred when Meadows started “using

manual levers . . . he ended up a little out of sequence when he was doing it manually and

left the ram bar down,” which created a “spike” in the pressure that over-pressurized a

defective valve. Sokalski testified that the valve “exploded” because Anchor omitted a

check valve when it refurbished the shield that was part of the original shield design and

would have relieved the over-pressurization. In hydraulic systems, the check valve is a

safety feature built into the device to sense and relieve excessive pressure by allowing the

over-pressurized fluid to flow back into the system to a relief valve, which is another

safety device on the system. After examining a number of Stecko valves, Sokalski found

that the threads of the male and female connections of the valve were incorrectly cut,

rendering the valve subject to failure at pressures below its expected failure pressure.

Though he admitted that he could not replicate the exact conditions of the mine shield’s

hydraulic system when it failed in his testing , he testified that, using principles of

physics, a pressure spike was caused in the hydraulic fluid within the shield system that

contributed to the failure of the Stecko valve.

       Invoking the District Court’s diversity jurisdiction, appellants filed, on November

29, 2002, a multi-count complaint against Anchor alleging negligence and strict liability

under the Restatement (Second) of Torts § 402A. Once discovery showed that the shield



                                               5
in question was likely Shield # 45, Anchor filed a third-party complaint joining Lewis

Goetz and Company and Stecko, respectively the supplier and the manufacturer of the

valve in question, seeking indemnity/and or contribution. The District Court granted

Lewis-Goetz’s unopposed motion for summary judgment because no party could prove

that the valve in appellants’ counsel’s custody was supplied by Lewis-Goetz.

       Anchor then filed a motion for partial summary judgment with regard to

appellants’ strict liability claim which the District Court granted on April 17, 2006 on the

basis that Anchor did not sell or supply a product but rather provided a service which is

not subject to strict liability claims. On August 28, 2006, the Court granted Stecko’s

motion for partial summary judgment with regard to any claim of Anchor against Stecko

for indemnity, finding that none of the theories of liability Anchor asserted against Stecko

would support such a claim. Next, on January 5, 2007 the Court sua sponte granted

summary judgment as to any claims for contribution by Anchor against Stecko, finding

that no evidence identified by Anchor supported a claim for strict liability against Stecko.

       Appellants’ negligence claim against Anchor was the only remaining claim. After

the close of discovery, Anchor filed a motion in limine to exclude the testimony of

appellants’ only expert on liability and causation, Sokalski. After a hearing on February

1, 2007, the District Court made a determination that the proposed testimony did not meet

the requirements for expert testimony under Federal Rule of Evidence 702 and the factors

outlined by the Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509



                                             

, 589 (1993), because it was insufficient, not based on an appropriate foundation,

and inadequately tied to the facts of the case. After excluding Sokalski’s testimony, the

District Court granted final judgment in favor of Anchor on May 3, 2007. Appellants

filed a timely notice of appeal on May 23, 2007.

                                              II.

       The District Court had jurisdiction over this diversity action under 28 U.S.C. §

1332. We have jurisdiction over the final orders of the District Court pursuant to 28

U.S.C. § 1291.

       We exercise plenary review over the District Court’s decision to grant summary

judgment. NBT Bank Nat’l Assoc. v. First Nat’l Comm. Bank, 

, 409 (3d

Cir. 2004). “Affirming the grant of summary judgment is proper where there are no

genuine issues of material fact and the moving party is entitled to judgment as a matter of

law.” 

We resolve all factual doubts and draw all reasonable

inferences in favor of the nonmoving party. See DL Res. Inc. v. FirstEnergy Solutions

Corp., 

, 216 (3d Cir. 2007).

       In reviewing the exclusion of expert testimony under Daubert, we must determine

whether the District Court abused its discretion. Pineda v. Ford Motor Co., 

,

243 (3d Cir. 2008). “An abuse of discretion arises when the District Court's decision rests

upon a clearly erroneous finding of fact, an errant conclusion of law or an improper

application of law to fact.” In re TMI Litig., 

, 666 (3d Cir. 1999) (internal



                                             7
quotation marks omitted). This Court does not interfere with the District Court's decision

“unless there is a definite and firm conviction that the [District Court] committed a clear

error of judgment in the conclusion it reached upon a weighing of the relevant factors.”

marks omitted). To the extent that the District Court's decision

involved a legal interpretation of the Rules of Evidence, the review is plenary. See 

    Strict Liability Claim

       The District Court properly granted summary judgment on appellant’s claim for

strict liability against Anchor, finding that Anchor serviced but did not manufacture or

redesign the allegedly defective product. Meadows’ complaint, inter alia, alleged that

Anchor was liable on a theory of strict liability under the Restatement (Second) of Torts §

402A. Specifically, Meadows alleged that Anchor did not engage solely in servicing the

longwall shield that caused his injury but defectively redesigned, refurbished, re-

manufactured and reconditioned it. The District Court granted summary judgment in

favor of Anchor and found that § 402A does not apply to a defendant such as Anchor who

neither sold nor manufactured the allegedly defective valve.

       Restatement (Second) of Torts § 402A states that:

       (1) One who sells any product in a defective condition unreasonably
       dangerous to the seller or consumer or to his property is subject to liability
       for physical harm thereby caused to the ultimate user or consumer, or to his
       property, if
                  (a) the seller is engaged in the business of selling such a product,
                 and

                                                      8
                  (b) it is expected to and does reach the user or consumer without
                 substantial change in the condition in which it is sold.
       (2) The rule stated in Subsection (1) applies although
                  (a) the seller has exercised all possible care in the preparation and
                 sale of his product, and
                  (b) the user or consumer has not bought the product from or
                 entered into any contractual relation with the seller.

Pennsylvania adopted this provision in Webb v. Zern, 

(1966). Comment f

to Section 402A further explains that the section “applies to any manufacturer of such a

product, to any wholesale or retail dealer or distributor . . . . It is not necessary that the

seller be engaged solely in the business of selling such products.” See also Malloy v.

Doty Conveyor, 

, 220 (E.D. Pa. 1993), quoting Burch v. Sears, Roebuck

& Co., 

, 621 (Pa. Super. Ct. 1983), noting that a “seller” includes “all

suppliers of a defective product in the chain of distribution, whether retailers, partmakers,

assemblers, owners, sellers, lessors or any other relevant category.” See also Salvador v.

Atlantic Steel Boiler Co., 

(Pa. Super. Ct. 1973), noting that a manufacturer

of a defective product is liable under 402A regardless of whether the manufacturer is

involved in the item’s sale.

       Service providers have long been excluded from strict liability. See La Rossa v.

Scientific Design Co., 

, 942-43 (3d Cir. 1968) (interpreting New Jersey law

and holding that, unlike mass produced goods, services are not marketed to a wide variety

of the general public, so parties injured by poor services are in a better position to locate

the tortfeasor and identify the defect caused by the tortfeasor's negligence); Lemley v. J &



                                                9
B Tire Co., 

, 1379-80 (W.D. Pa. 1977) (noting that there had been no

expansion of Section 402A to include persons who supply a service).

       Appellants argue that the District Court erred in determining that Anchor was not a

manufacturer or seller of a product under § 402A because they allege that Anchor, in

repairing and refurbishing the longwall shields, “redesigned” the hydraulic system and

“sold” the redesigned system back to the Mine. Appellants point to the deposition

testimony of the chief engineer at Anchor at the time of the longwall shield repair project,

Edmond Groff that he made changes to the circuit or hydraulic drawings of Shield # 45 as

evidence that his drawings constituted a modification of the original manufacturer’s

drawings of the hydraulic system. Appellants argue that Anchor performed a design

function by modifying the original manufacturer’s drawings and therefore engaged in an

act that put itself in a position of a manufacturer. Anchor contends that, while Groff

made a drawing of the hydraulic system, the hydraulic system was designed by the

original equipment manufacturer, Meco-Dowty, and that any changes or modifications to

the system were specifically requested and approved by the Mine. Anchor argues and

presented evidence that it did not manufacture, purchase, sell or supply the shield at issue

or the allegedly faulty valve that caused the injuries but merely attached the component to

the shield unaltered from the way it was received from the manufacturer, appellee Stecko,

and that the shields themselves were at all times owned by the Mine.

       Pennsylvania law does recognize strict liability for a manufacturer of a product



                                             10
regardless of whether the manufacturer was involved in the sale. See Webb v. Zern, 

(Pa. 1966). But adopting Meadows’ theory that, by refurbishing and repairing

the longwall shield, Anchor “redesigned,” manufactured and sold a product to the Mine

would effectively swallow the distinction between sellers of products and those that

simply provide a service for the products after manufacturing. From the evidence in the

record, Anchor did not hold itself out to be the seller of products such as valves or

longwall shields. No evidence was presented to contradict that any changes in the

drawings at issue were made at the request of the Mine and ultimately approved by the

Mine. Further, no evidence was presented to contradict that the parts that Anchor used in

refurbishing and repairing the shields were purchased in cooperation with the Mine.

       Appellants also claim that Anchor is a “seller” under Section 402A because it

played a role in requesting additional parts. However, this claim fails because any such

requests by Anchor were merely incidental to servicing the shields as specified by the

Mine and appellants have presented no evidence that the parts requested are the allegedly

defective products at issue here. Finally, there is no evidence that Anchor was paid for

any alleged redesign by the Mine as part of the repair project. Appellants provide no case

law to support their theory that repairing and refurbishing constitutes “re-manufacturing”

and “re-designing” under Pennsylvania law.2 Anchor provided a service: the repair and

       2
       Appellants also attempt to get around the seller distinction by arguing that Anchor
was a bailee of the longwall shield and that bailment can give rise to a claim under §
402A. See Berkbile v. Brantly Helicopter Corp., 

, 898 n.3 (Pa. 1975).
Appellants cite Kalumetals, Inc. v. Hitachi, 

(W.D. Pa. 1998), for

                                             11
refurbishment of 39 of the Mines’ longwall shields. We decline to hold that in repairing a

longwall shield Anchor was involved in “re-designing” or “re-manufacturing.”

       The public policy considerations underlying strict liability also argue against

holding that Anchor was a “seller” of products. The controlling question in whether

someone qualifies as a seller, as Pennsylvania courts have pointed out, is the relationship

between the defective product and the overall chain of distribution. See Frey v. Harley

Davidson Motor Co., 

, 17 (Pa. Super. Ct. 1999). The Pennsylvania Supreme

Court has followed a four-part test in determining whether public policy requires the

imposition of strict liability on a supplier of an allegedly defective product: (1) whether

defendant is the only member of the marketing chain available to injured plaintiff; (2)

whether the imposition of strict liability would serve as an incentive to safety; (3) whether

defendant is in a better position than the consumer to prevent the circulation of defective

products; and (4) whether defendant can distribute the cost of compensating for injuries

resulting from defective products by charging for it in its business. Francioni v. Gibsonia

Truck Corp., 

, 739-40 (Pa. 1977).



support that § 402A applies in a bailment relationship. However, the Kalumetals analogy
would apply only if an Anchor employee had been injured while working on a defective
longwall shield. We fail to see how Kalumetals applies to Meadows’ accident. Once the
longwall shields were returned to the Mine, the bailer/bailee relationship terminated. See
American Enka Co. v. Wicaco Mach. Corp., 

, 1053 (3d Cir. 1982), holding
that “[a] bailment is a delivery or deposit of personalty under an implied or express
agreement that at the termination of the bailment the personalty will be redelivered to the
bailor, otherwise dealt with according to the bailor's directions, or kept until the bailor
reclaims it.”

                                             12
       First, as Anchor points out, appellants could have sued Meco-Dowty, the

manufacturer of the longwall shield, or Stecko, the manufacturer of the allegedly

defective valve. Second, imposing liability on Anchor would not serve as an incentive to

safety since Anchor is not in the business of building, designing or manufacturing the

shields or valves and therefore does not have control over the safety of the products.

Similarly, Anchor is in no better position than the consumer to influence the

manufacturing of safer mining products or prevent circulation of defective mining

products because it acquired the products from the consumer for repair and was not in the

original or direct chain of distribution. Anchor repaired only 39 of the Mine’s shields; it

was not mass producing the shields and valves. Finally, although Anchor could charge

extra for its services to cover the potential cost of compensation for injuries, it ought not

be required to distribute the cost of defects in products it did not design or manufacture.

       Thus, the District Court properly granted summary judgment on the strict liability

claim, as Meadows’ allegations involved Anchor’s service activities as a repairer rather

than as a “seller” and such a claim sounds in negligence. See La 

-

43; 

.

B.     Exclusion of Expert Witness Testimony

       The District Court did not abuse its discretion in excluding the testimony of

appellants’ expert witness, Sokalski. His testimony was Meadows’ sole evidence of

negligence. The Court found that Sokalski’s testimony was not reliable under Rule 702



                                              13
and so excluded his testimony and granted final judgment in favor of Anchor because the

negligence claim was the only claim remaining after the Court granted Anchor’s motion

for partial summary judgment on strict liability.

       Sokalski’s opinion is based on several conclusions. First, Sokalski testified that

the Stecko valve that struck Meadows in the eye was defective because its male threads

were over-cut, which reduced its ability to fully and tightly grip the female threads,

thereby reducing the burst pressure to approximately one-half of its published design.

Second, Sokalski concluded that the mine’s hydraulic system, which normally operates at

between 1700 pounds per square inch (“psi”) and 3200 psi, experienced a “spike” in

pressure exceeding 100,000 psi on the Stecko valve. Third, Sokalski concluded that the

spike was generated due to the ram bar on the shield being in the “down” position.

Fourth, Sokalski concluded that there was no check valve between the two hoses that

would have connected into the valve assembly and would have prevented the pressure

spike. Lastly, he concluded that because the ball in the allegedly malfunctioning valve

was “ovalled” and dented, extremely high pressure occurred there. Essentially, Sokalski

alleged two defects in the shield after Anchor’s repairs were completed that caused the

accident: the presence of the ram bar in the down position that generated the spike in

pressure and the absence of a check valve that would have prevented the valve from

separating when the alleged spike occurred.

       Sokalski testified regarding the tests he used to reach his conclusions. He



                                              14
purchased three Stecko ball valves from the lot that was the source of the allegedly

defective valve. He then connected the valves to a metal pipe filed with water and slowly

increased the pressure on the water pipe with an air pump. He tested two of the valves in

both the “open” and the “closed” positions. According to his tests, the valves failed at the

13,000 and 15,000 psi range by “an infinitesimal leak” of water escaping from the valve.

       Meadows argues that the District Court abused its discretion in precluding

Sokalski’s testimony under Fed. R. Evid. 702 and Daubert. Rule 702 has three

requirements: (1) the proffered witness must be an expert, i.e., must be qualified; (2) the

expert must testify about matters requiring scientific, technical or specialized knowledge,

i.e., must be reliable; and (3) the expert’s testimony must assist the trier of fact, i.e., must

be fit. See 

; In re Paoli R.R. Yard PCB Litig., 

, 741-

42 (3d Cir. 1994).

       First, to qualify as an expert under the rule, under our liberal standard, a witness

must possess sufficient qualifications in the form of knowledge, skills and training.

, citing In re 

. The District Court found that

Sokalski has sufficient qualifications as a professional engineer to testify as an

engineering expert under Rule 702 and the parties do not contest this finding.

       The second requirement is that of reliability. According to Rule 702, “an expert’s

testimony is admissible so long as the process or technique the expert used in formulating

the opinion is reliable.

. While a

litigant must make more than a prima facie showing that his expert's methodology is

reliable, we have cautioned that “[t]he evidentiary requirement of reliability is lower than

the merits standard of correctness.” 

The admissibility decision must focus on

the expert’s methods and reasoning, and credibility decisions should not be considered

until after admissibility has been determined.

. The

language of Rule 702 requiring the expert to testify to scientific knowledge means that the

expert's opinion must be based on the “methods and procedures of science” rather than on

“subjective belief or unsupported speculation”; the expert must have “good grounds” for

his or her belief. In re 

, citing

Daubert holds that an inquiry into the reliability of scientific evidence under Rule 702

requires a determination as to its scientific validity.

n.9.

       A trial court may consider several factors in evaluating whether a methodology is

reliable, including but not limited to: (1) whether a method consists of a testable

hypothesis; (2) whether the method has been subject to peer review; (3) the known or

potential rate of error, (4) the existence and maintenance of standards controlling the

technique’s operation; (5) whether the method is generally accepted; (6) the relationship

of the technique to methods which have been established to be reliable; (7) the

qualifications of the expert witness testifying based on the methodology; and (8) the non-

       Appellants assert that the District Court abused its discretion by, in effect, holding

the expert to a higher standard of admissibility than required under our case law.

Specifically, appellants contend that because Sokalski’s testimony concluding that

excessive pressure caused hydraulic system failure was based on generally accepted

principles of basic physics (recognized since the time of Sir Isaac Newton), it should have

been deemed reliable. Appellants note that this Court affirmed the decision of a District

Court not to exclude testimony based in part upon general engineering principles. Stecyk

Stecyk v. Bell Helicopter Textron, Inc., 

, 412 (3d Cir. 2002). In Stecyk,

defendant General Motors argued that plaintiffs’ expert utilized general engineering

principles to address leakage in the allegedly defective seal without any actual proof of a

defect. Stecyk, 

, at *7. In addition to general engineering principles,

however, the expert supported his theory with substantial physical and reliable

documentary evidence. Thus, the Court allowed the testimony because the expert

supplemented his conclusions based on general engineering principles with reliable

methodology. 

       In this case, as the District Court points out, Sokalski’s methodology was not

reliable. Sokalski did not attempt to replicate the conditions in the longwall shield at the

time of the accident; instead, he tested the valves without the hoses or connectors and

slowly increased pressure. Sokalski did not examine the specific shield that Meadows

was working on at the time of the accident because it was returned to service in the Mine

so he could not say definitively whether the shield contained a check valve. Further, there

was no reference to material, publication or literature describing the failure scenario he

presented, no evidence that his methodology was subjected to peer review or that it is

generally accepted, no outside documentary evidence, aside from his own report,

supporting his conclusions, no evidence concerning any known or potential error rates in

his testing, and no control standards. Finally, Sokalski conceded that his pressure tests

did not replicate the accident as he hypothesized that it had occurred because he tested the



                                             18
valve by increasing the pressure slowly using a pump instead of generating the dynamic

spike he conceded occurred at the time of the accident; also his tests did not replicate the

assembly of the hoses, connectors and Stecko block valve that existed in the mine because

he did not use any hoses or connectors in his tests. Moreover, he did not research the

maximum burst pressure of the hoses or connectors or otherwise test them with or without

a check valve. The District Court noted that he speculated that had he used hoses and

created a dynamic spike in pressure like the one he opines occurred in the accident the

valve would have separated before the hoses would have blown. As the District Court

noted, the expert’s own testing did not support his hypothesis.3 Thus it was not the

“general physics principles” with which the District Court took issue, but rather the

method by which Sokalski applied the principles to the facts of Meadows’ accident.

Here, the analytical gap between the data and the opinion proffered is too great and is

connected only by the ipse dixit of the expert, not by any evidence. General Elec. 

. Thus, the District Court properly excluded Sokalski’s testimony because

it failed to meet the reliability standard.

          As appellant correctly noted, testing need only be reasonably similar to the actual
events. Substantial similarity does not require perfect identity between actual and
experimental conditions.

admitted even if conditions do not perfectly correspond to the conditions at issue in
litigation; dissimilarities may affect the weight of the evidence, but not its admissibility.

on the record, it

substantially similar to the incident.

assist the trier of fact, “goes primarily to relevance.” Lauria v. Amtrak,

for the factor is not high; it is met when there is a clear “fit” connecting the

issue in the case with the expert’s opinion that will aid the jury in determining an issue in

the case. 

, quoting 

. “Rule 702's

‘helpfulness' standard requires a valid scientific connection to the pertinent inquiry as a

precondition to admissibility.” 

. In other words,

expert testimony based on assumptions lacking factual foundation in the record is

properly excluded. See 

.

       Appellants assert that the District Court wrongly rejected Sokalski’s opinion that

the accident was caused by Anchor’s failure to install a check valve on Shield # 45.

Sokalski testified that the original manufacturer’s specifications and Anchor’s schematics

indicated that a check valve was to be installed in order to allow the hydraulic fluid to

flow back into the system to a relief valve if the pressure on the base lift jack exceeded

acceptable limits. Sokalski testified that he examined the drawings done by Anchor and

observed that no check valves were indicated on Anchor’s schematics, but Groff’s

uncontroverted testimony established that the diagram Sokalski relied upon represented a

layout of the location of the hoses in the hydraulic system and that the original schematic



                                              20
by Meco-Dowty contains all of the component parts, including the check valves.

Moreover, the District Court found that, as Anchor ordered 50 check valves for the 39

machines they refurbished for the Mine and as Sokalski admitted that he did not know

first-hand whether a check valve was installed in the shield at issue because he did not

inspect it, Sokalski’s testimony regarding the absence of the check valve did not fit with

the otherwise uncontroverted evidence before the Court.

       Additionally, there was no “fit” between Sokalski’s testing of the Stecko valve and

the facts. As previously noted, the testing did not replicate the hose assembly and he did

not subject the valves to the dynamic pressure spike he alleges occurred. Neither did the

tests he conducted on the Stecko valve duplicate the results that occurred in the mine, as

no valve separated in these tests - a small amount of water leaked instead - and there was

no evidence of any ovalling or indentation on the ball portion of the valve. The District

Court correctly noted that “[g]iven the lack of resemblance Sokalski’s tests have to the

events in the mine, it is difficult to say how, if at all, these tests could assist the jury in

determining what caused the accident.”

       Appellants also argue that the District Court made a “de facto Summary Judgment”

decision on whether the longwall shield on which Meadows was working was equipped

with a base lift cylinder. Sokalski’s theory was that the “spike” in pressure was generated

by the base lift jack/cylinder portion of the shield because the ram bar was in the “down”

position. However, the evidence shows that when Shield # 45 was delivered to Anchor it



                                                21
did not contain a base lift ram bar or a base lift jack housing. According to Anchor’s

records, Anchor did not put in a new base lift ram bar or a new base lift housing during its

repairs and refurbishment of Shield # 45. Testimony by an inspector present at the Mine

on the date of the incident indicates that the shield Meadows was working on at the time

of the accident did not contain a base lift jack. No evidence was presented that the Mine

supplied or paid for a new base lift jack. Additionally, no evidence was presented to

contradict that the shield did not require a base lift jack to function.

       The only evidence that appellants point to in order to prove the existence of a base

lift cylinder in Shield # 45 was the equivocal deposition testimony of Groff that he

thought that the base lift ram bar would have been replaced before the longwall shield

was sent back to the Mine, not that he knew that it was replaced on Shield # 45. Thus,

Sokalski’s opinion, which depended on the existence of a base lift jack on Shield # 45 to

cause the pressure increase, lacked a factual foundation in the record to satisfy the fit

requirement and was properly excluded by the District Court. See 

.

       Appellants argue that a factual dispute existed as to whether a base lift jack was

attached to Shield # 45 because Anchor’s paperwork was not correct or that a shield other

than Shield # 45 was involved in the accident. However, as the District Court properly

noted, appellants produced no evidence at the Daubert hearing that the paperwork was

incorrect or that the incorrect shield had been identified in discovery. The photograph



                                              22
that appellants allege supports that a base lift jack was on Shield # 45 at best suggests that

the incorrect shield had been identified. However, as Anchor only refurbished 39 of the

189 shields in the Mine repair project, Meadows would have had to also identify that the

malfunctioned shield was refurbished by Anchor because it would have been possible that

Anchor did not repair the relevant shield if it was not Shield # 45. Thus, if Shield # 45

was correctly identified, it did not have a base lift jack so it could not have malfunctioned

in the way that Sokalski opined caused the accident. If Shield # 45 was not correctly

identified as the mine shield at issue, no evidence existed that this unidentified shield was

one that Anchor repaired.

         For the foregoing reasons, we find that the District Court did not abuse its

discretion in excluding the testimony of appellants’ expert witness. Sokalski’s testimony

failed to meet the reliability and fit requirements for admitting expert testimony and was

therefore properly excluded under both, although either would have been sufficient.

C.       Dismissal of System Stecko

         Appellants’ challenge of the District Court’s sua sponte grant of summary

judgment in favor of third-party defendant Stecko is moot. On January 5, 2007, the

District Court sua sponte granted summary judgment for Stecko on Anchor’s contribution

claims against Stecko. Anchor did not oppose the summary judgment, as its expert had

found no manufacturing defects in the Stecko valve components.4 Anchor does not now

     4
     Stecko has filed an unopposed motion to file a surreply brief. That motion is
granted.

                                               23
appeal the grant of summary judgment in favor of Stecko.

       Appellants argue, as they did before the District Court, that because their expert

found a defect in the Stecko valve there was a genuine issue of material fact precluding

the dismissal of Stecko because the jury could find that the Stecko valve was defective

and caused the failure resulting in Meadows’ injury. Appellants are here seeking to admit

evidence against a party they did not sue in support of a claim abandoned by the party

who raised it. Pursuant to Federal Rule of Civil Procedure 14, a plaintiff cannot recover

against a third-party defendant unless the plaintiff amends his complaint and files a direct

action against the third-party defendant. See Fed. R. Civ. P. 14(b); see also George v.

Brehm, 

, 246 (W.D. Pa. 1965). Here, despite being given an opportunity

to do so, appellants failed to amend their complaint or to seek to amend their complaint

out of time to bring an action against Stecko under Rule 14. We therefore need not

consider whether the District Court should have taken Sokalski’s testimony into account

in granting summary judgment for Stecko against Anchor. Because we affirmed the

Court’s exclusion of Sokalski’s testimony and appellants have not filed a claim against

Stecko or amended their complaint to bring an action against Stecko, the issue is moot.

       For the foregoing reasons, we affirm the judgment of the District Court in its

entirety.
