MEMORANDUM AND ORDER
Defendant Amtel, Inc. has moved for summary judgment. 1 The resolution of this motion depends upon whether the manufacturer of a component part which was manufactured to the specifications of a third party and in which there was no manufacturing defect can be held liable for a design defect allegedly stemming from the use to which the third party put the part.
This case arises from the crash of a helicopter in Jeddah, Saudi Arabia, which was unloading a freighter anchored in that port. The helicopter crashed into the hold of the ship, killing the pilot. These suits were brought by the representative of the deceased pilot and by the insurer of the helicopter. The defendants are United Technologies Corporation (UTC) which through its Sikorsky division manufactured the helicopter and Amtel, Inc. (Amtel) which through its Fenn Manufacturing division (Fenn) machined the “stationary star” (star) of the helicopter. A stationary star is a portion of the main rotor head assembly on a helicopter. It is undisputed that following the crash the stationary star of the helicopter in question was in a fractured condition. The plaintiffs allege that the star, weakened by fatigue cracks broke apart while the helicopter was in flight, thus causing the accident. The defendants claim that the star was fractured by the force of the crash.
Plaintiffs’ complaint asserts claims based on negligence and strict liability. The complaint alleges that both defendants were negligent as to the design, manufacture, and inspection of the helicopter and the star. The strict liability claim alleges defective design and manufacture. In addition, the plaintiffs also assert negligence and strict liability based on the failure of both defendants to warn potential users of the defective condition of the helicopter and the star.
The allegations of the complaint are not determinative. On a motion for summary judgment, I may consider affidavits, depositions, answers to interrogatories and like matter. In this case, Amtel directs my attention to interrogatories it served on the *175 plaintiffs which inquired, inter alia, whether or not the plaintiffs alleged that the stationary star was defectively machined. Plaintiffs’ response was as follows: “As of the date of serving this supplemental answer [December 27, 1979], Plaintiffs have no evidence available to them of a machining defect in the stationary star that was installed on the Aircraft at the time of the crash.” Plaintiffs have not supplemented this answer. The stationary star is the property of the plaintiff, Orion Insurance Company, which as the insurer of the helicopter now owns the wreckage. Thus, except for the time when the star was being tested by the defendants, plaintiffs have had since 1976 when the crash occurred to examine the star for a manufacturing defect. Furthermore, before the answer was filed both the plaintiffs and defendant, UTC, had extensively tested the star and neither found a machining defect. Thus, although plaintiffs’ answer above is styled as if further testing would be forthcoming, it is really a concession that there is no evidence to create a factual issue regarding the manufacture of the star. 2
It is clear that Amtel’s only involvement with the events which gave rise to this lawsuit is the fact that it “machined” the stars for Sikorsky’s helicopters. The already forged stars would arrive at Amtel’s Fenn division. Fenn personnel would then machine the star to the specifications provided by Sikorsky. The machining process included “lathing of the interior diameter of the stationary star, and grinding the star to various dimensions.” Fenn inspectors would inspect the star after the process and then pass it along to Sikorsky inspectors located at the Fenn plant, if the star met with their approval then it would be placed in a bonded storage area. Fenn also machined an inner collar for the star which like the star was manufactured to specifications supplied by Sikorsky, and inspected by Sikorsky personnel.
The drafters of the Federal Rules of Civil Procedure anticipated that discovery would serve to narrow the allegations of the complaint.
Hickman v. Taylor,
To answer this question, I must integrate two little explored lines of precedent: the liability of one who manufactures his product according to specifications of his commercial buyer and the liability of component parts manufacturers when the final product into which their component was incorporated causes injury. These two lines are pertinent because Fenn manufactured the star to Sikorsky’s specifications and then sold the product to Sikorsky and because the design defect arose in this case, if at all, from Sikorsky’s incorporation of the star into their final product, the helicopter.

Before applying these rules to the present case, I note that this case may be governed by Pennsylvania law so I must consider whether the Pennsylvania Supreme Court’s opinion in
Azzarello v. Black Bros., Co.,
In
Azzarello,
the Pennsylvania Supreme Court held that negligence concepts have no place in Pennsylvania 402A law so far as the trial, evidence, and jury charge are concerned.
See Azzarello
v.
Black Bros., Co.,
With respect to the negligence count, it cannot be said that in relying on the Sikorsky specifications the defendant, Amtel, acted unreasonably. They had a past course of dealings with Sikorsky. Sikorsky had an established reputation for producing aircraft. It was not unreasonable as a matter of law for Amtel to rely on the plans.
On the issue of whether Amtel can be held strictly liable it appears that similar considerations apply. Amtel was dealing not with specifications submitted by a consumer but by a business entity with superi- or knowledge in the field of aviation.
In
Taylor v. Abbe, Inc.,
In a similar case,
Verge v. Ford Motor Co.,
I think that the present case is squarely within the precedent of
Taylor
and
Verge.
As the
Taylor
court noted, “[tjhere is no dispute ... with respect to the critical facts, and thus the only issue before [me] is the legal significance of those facts.”
Plaintiffs also state a claim based upon Amtel’s failure to warn. This allegation is based on what the defendant reasonably knew or should have known. In strict liability, the duty to warn arises when a product is defective (“unavoidably unsafe”) and the defect cannot be remedied by any currently known means. In this situation the product is not defective within the meaning of § 402A if it is accompanied by a warning. See Restatement (Second) of Torts § 402A, Comment k. With respect to these claims, the following facts bear repeating: (1) there was no manufacturing defect in the star (2) Sikorsky set the specifications for the star (3) the star in question went through two inspections, one by Fenn personnel and one by Sikorsky personnel, before it was accepted to ensure that it met those specifications (4) Sikorsky is in the business of manufacturing aircraft; Fenn is not and (5) I have held that as a matter of law it was reasonable for Fenn to rely upon Sikorsky’s specifications.
On the negligence count, assuming for the purposes of this motion, only, that the star as constructed per the Sikorsky specification was inadequate for the purpose to which Sikorsky put it, there is no reason why defendant Amtel (through Fenn) should have known this. To establish a duty to warn, the plaintiffs rely upon the fact that after the production of the star involved in this crash, the alloy from which the star was made was changed. Plaintiffs contend that when Amtel received the star forged from a different alloy they had a duty to investigate the reason for the change. Such an investigation, the plaintiffs maintain, would have revealed that the reason for the change was Sikorsky had determined that the stars made of the old alloy were defective. Having discovered this, according to the plaintiffs Amtel would then had had a duty to contact the purchasers of Sikorsky helicopters and inform them of the risk. I.believe that this extraordinary series of “duties” defies common sense. There is nothing in the record to show that Amtel in fact knew the reason for the substitution of a new alloy. The law does not impose a duty upon a manufacturer in Amtel’s position to undertake an independent investigation as suggested.
*178
On the strict liability count, I have already observed that the Third Circuit has said that § 402A has implicitly within it the notion that a manufacturer should not be held liable unless his product is responsible for the injury.
See Verge v. Ford Motor Co.,
Finally, no public policy can be served by imposing a civil penalty on a manufacturer of specialized parts for a highly technical machine according to the specifications supplied by one who is expert at assembling these technical machines, who does so without questioning the plans or warning of ultimate user. The effect of such a decision on component parts manufacturers would be enormous. They would be forced to retain private experts to review an assembler’s plans and to evaluate the soundness of the proposed use of the manufacturer’s parts. The added cost of such a procedure both financially and in terms of stifled innovation outweighs the public benefit of giving plaintiffs an additional pocket to look to for recovery. I believe the better view is to leave the liability for design defects where it belongs and where it now is-with the originator and implementer of the design-the assembler of the finished product.
ORDER
NOW, October 28, 1980, upon consideration of the defendant Amtel, Inc.’s motion for summary judgment which I consider under Rule 78 without oral hearing, memoranda submitted by the parties and for the reasons stated in the accompanying memorandum, IT IS ORDERED that the motion is GRANTED.
Notes
. In reaching a decision on this motion, I rely on memoranda submitted by Amtel, the reasoning of which I generally adopt and approve.
. Plaintiffs have agreed that further discovery of Amtel would not lead to the discovery of a manufacturing defect. They declined the benefit of a special discovery period in which to develop additional facts to support their theoríes against Amtel, conceding that they will not be prejudiced by a decision of this motion on the current record.
