Aviation & Complex Litigation

During the last three decades, the members of this practice group have, on a regular basis, represented virtually all aspects of the aviation industry including: aircraft manufacturers, suppliers of steel and forgings used in aircraft components, suppliers of aviation ground support equipment, operators, pilots and airport facilities. As set forth below, the matters have involved questions of liability for the major recall of aircraft components, where more than $100 million was at stake, to operators of business jets, to persons injured in hot air balloon rides.

We have also represented commercial operators and pilots in licensing and administration proceedings before the Federal Aviation Administration and the National Transportation Safety Board.
 
The members of the group are intimately familiar with various aspects of aviation activities and operations. The chair of the group has been a licensed and active instrument-rated pilot for over 30 years. Another member of the group holds his airline transport pilot certificate, along with a gold medallion flight instructor certificate, and was formerly a captain for a regional airline and first officer for Trans World Airlines on the MD-80 aircraft. Two other members have also trained as pilots, with one successfully building and operating his own home-built airplane. Members of the group are active in numerous trade and profession-related associations, including the Aviation Insurance Association and the Lawyer-Pilot's Bar Association.
 
Because of the broad range of activities that occur within the aviation industry, and the often catastrophic results when an aviation activity goes awry, each aviation liability claim often has very unique circumstances and issues. Due to the likelihood of serious damage to or destruction of the product involved, the members of our aviation litigation group are often engaged by the parties or their insurers shortly after an event occurs to assist in structuring the investigation and assembling the team of experts to conduct such testing, accident reconstruction, and failure analysis as may be necessary to determine the cause of the event.
 
The experience gained in years of handling complex aviation and product liability cases has easily translated to the litigation of other commercial disputes where technology and product operation is at issue. The use of techniques such as finite element analysis, scanning electron microscopy, focused ion beam analysis and computerized recreation and depiction of critical events are techniques that easily transfer to and provide a significant advantage in the handling of litigation of numerous disputes that arise, not just in aviation matters but in various commercial settings. It is a combination that brings together the access to and understanding of these technologies and expertise, with the experience of trying to verdict protracted complex legal matters, that enables us to provide effective advocacy to clients who come to us for legal representation.

Representative Cases and Clients

  • We represented a major regional specialty steel company that melted and forged ingots from which aircraft engine components were later made. An engine manufacturer to whom the steel was sold underwent an $80 million recall due to a series of faulty crankshafts and claimed that the crankshafts were defective because of inherent defects in the supplied steel. After a four-week trial in the Philadelphia Court of Common Pleas, the jury concluded that the evidence proffered by our experts, including extensive testing and sophisticated analysis, established that the steel was not defective in its inherent structure.
  • A major manufacturer of seats used in corporate and commercial jets was sued after the crash of a corporate jet resulted in a brain injury disabling a senior executive. It was alleged that this was due to seat failure from the impact sequence. Through reconstruction of seat components and analysis by biomechanical engineers, which established that the seat could not have failed as alleged by the plaintiff, the plaintiff's expert was discredited in a pre-trial hearing and the case settled favorably for the seat manufacturer.
  • A propeller manufacturer was sued when a propeller failed in flight in a single-engine aircraft requiring an attempted emergency landing in which the pilot and his wife died, and their eight-year-old daughter, who was substantially injured, watched her parents expire post-accident. The propeller manufacturer admitted that it had a defective decal that would lead to corrosion of propeller at the point where failure occurred, but through maintenance experts and metallurgists, we were able to show that the manufacturer had provided specific instructions for removal of the defective decal, which were not followed.
  • We represented a leading forger of commercial transportation parts that had forged crankshafts used in aircraft engines. After several fatal crashes, and other reported crankshaft failures, the aircraft manufacturer initiated a $100 million-plus recall and claimed that the crankshaft defects were the result of forging problems. After a two-month trial in Texas, the jury returned a verdict finding that the forging company did not create any defects in the crankshaft and that the crankshaft defects resulted from design problems.
  • A leading manufacturer of specialty polyurethane materials was sued regarding alleged defective equipment provided by the designer and manufacturer of high speed polyurethane mixing equipment used in association with robotic manufacturing process. After a two-month trial, a federal jury in Philadelphia awarded the polyurethane manufacturer in excess of $12 million against the supplier of the defective mixing equipment.
  • On behalf of a leading manufacturer of airblast equipment, we are acting as personal counsel in advising the manufacturer regarding more than 10,000 lawsuits around the country, interfacing with insurance counsel assigned to represent the client as an insured, and participation in the structuring of the national defense strategy for handling the claims while at the same time administering the coverage issues relating to claims among the various insurers.

Reversal Obtained in Pennsylvania Superior Court Regarding Denial of Objections to Venue

We obtained a reversal in the Pennsylvania Superior Court of the trial court’s denial of preliminary objections to venue. We successfully moved in the trial court for certification of the ruling pursuant to Pa.R.A.P. 311(b) so that an immediate appeal from the interlocutory ruling could be taken, and we subsequently prevailed on appeal. The litigation arose from a helicopter accident that occurred in Afghanistan. Both plaintiffs, husband and wife, resided in Arizona. Our client is a Delaware corporation located in Bucks County, Pennsylvania, that refurbished the helicopter. The codefendant corporation leased the helicopter to the plaintiff-husband’s employer, which was organized and principally operates in Montana. The plaintiffs’ primary focus in seeking to establish venue was on our client and, in particular, on the fact that it purchased two fabric interiors from a Philadelphia vendor. The Superior Court determined that the business dealings of our client did not constitute actual business conducted in Philadelphia County. It stressed that “doing business with a Philadelphia County company does not amount to doing business in Philadelphia County if the obtained goods, services, or personnel are utilized elsewhere to further the defendant’s business activities.” As to the codefendant, the Superior Court concluded the limited venue evidence pointed to a separate but related corporate entity, and that the evidence failed to show the co-defendant regularly conducts business in Philadelphia County. Because there was no evidence to support the imputation of a separate entity’s contacts with Philadelphia on the co-defendant, venue as to the co-defendant was also improper.

The Ohio Supreme Court Extends Sham-Affidavit Rule to Contradictory Expert Reports

Legal Roundup: Ohio In its June 23, 2026, decision in Moore v. Mercy Medical Center, the Ohio Supreme Court upheld a trial court’s decision to strike an expert witness’s affidavit that contradicted the opinions expressed in the expert’s prior report. This case pertains to allegations of medical malpractice after plaintiff Cheri Moore gave birth to an infant in respiratory distress who required intubation. Moore alleged that a delay in ordering an emergency cesarean section resulted in the need for intubation, causing her child’s injuries. Specifically, Moore sued Dr. Meniru, who completed his first shift at 7:00 a.m. on May 28, 2015, and did not resume treating Moore until 7:00 a.m. on May 29, 2015. One of Moore’s expert witnesses authored a report stating that the doctors, including Dr. Meniru, deviated from the standard of care by not advocating for a cesarean section in the evening of May 28, 2015. Based on this report, Dr. Meniru moved for summary judgment, arguing that the alleged breach occurred during a period when he was not on duty. In response to the summary judgment motion, the plaintiff filed an affidavit from the same expert. Although the expert expressly incorporated his previous report into his affidavit, he also offered an additional opinion: that Dr. Meniru breached the standard of care by failing to begin a cesarean section within 30 minutes of receiving reports of fetal distress. Dr. Meniru filed a motion to strike the expert’s affidavit, arguing that it contradicted the opinions set forth in his prior report in violation of the sham-affidavit rule. The sham-affidavit rule applies to “a contradictory affidavit that indicates only that the affiant cannot maintain a consistent story, or is willing to offer a statement solely for the purpose of defeating summary judgment”. Moore, supra, at ¶ 19, citing Pettiford v. Aggarwal, 126 Ohio St.3d 413, 2010-Ohio-3237. The trial court granted both the motion to strike and the motion for summary judgment, and the Fifth District affirmed. The Ohio Supreme Court accepted two questions of law: (1) whether the sham-affidavit rule applies when the sworn testimony contradicts prior unsworn statements; and (2) whether an inconsistency within the affidavit goes to credibility or admissibility, justifying an order striking the affidavit. Previous rulings by the Ohio Supreme Court regarding the sham-affidavit rule have pertained to contradictions between an affidavit and sworn deposition testimony. See, e.g., Byrd v. Smith, 2006- Ohio-3455, 110 Ohio St.3d 24, 850 N.E.2d 47. However, here, the Court was asked to apply the same rule to contradictions between a sworn affidavit and an unsworn expert report. The Court held that, because Moore’s expert incorporated his prior report into his affidavit, he effectively adopted the report as part of his sworn testimony.

Pennsylvania Superior Court Reaffirms Liberal Pleading Standard in Medical Malpractice Actions

Legal Roundup: Pennsylvania The Pennsylvania Superior Court has reinforced a broader fact-pleading approach that may make it more difficult for health care defendants to obtain dismissal at the preliminary objection stage. In DaSilva v. Abington Memorial Hospital, the court held that the plaintiffs’ second amended complaint satisfied Pennsylvania’s fact‑pleading requirements despite the absence of individually named negligent actors. In DaSilva, the plaintiffs filed a second amended complaint alleging that Abington Memorial Hospital was directly and vicariously negligent after the patient, who was experiencing a mental health crisis, was left unattended by hospital staff, exited the emergency department, and was struck by a vehicle, suffering serious injuries. The trial court sustained the hospital’s preliminary objections and dismissed the complaint with prejudice, stating plaintiffs “failed to plead any material factual allegations in support of their claims of negligence [and] set forth vague allegations of negligence and unidentified agency.” Id. at *5. The plaintiffs appealed. On appeal, the Superior Court reversed, holding that the complaint sufficiently pled negligence and vicarious liability claims under Pa.R.C.P. 1019(a). The court concluded that allegations describing the patient’s condition, the hospital’s awareness of that condition, and the alleged failure to monitor or prevent elopement were adequate to satisfy Pennsylvania’s pleading requirements. Significantly, the court rejected the hospital’s argument that the complaint failed because it did not identify the specific employees responsible for the alleged negligence. Instead, the court found that generalized references to “emergency room staff” were sufficient to place the hospital on notice of the claims because “the names of those who performed services for the plaintiff are known to the defendant or can be ascertained during discovery.” Id. at *12 (citing Est. of Denmark ex rel. Hurst v. Williams, 117 A.3d 300, 307 (Pa. Super. 2015)). The effect of DaSilva is that plaintiffs may proceed past the pleading stage with relatively generalized allegations, particularly in cases involving institutional defendants where relevant details are uniquely within the defendant’s control. As a result, health care defendants should anticipate that challenges to claim sufficiency may be resolved in the later stages of litigation, including discovery and summary judgment.
