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.

Vendor Cyber Attack Compromises PII of More Than 3 Million Hunting and Fishing License Holders in Texas

The Texas Parks & Wildlife Department (TPWD) announced earlier this month that one of its vendors which handles the sale of state hunting and fishing licenses was the victim of a cybersecurity attack. The threat actor appears to have exfiltrated personal driver’s license information, passport numbers, email addresses, phone numbers and addresses of over 3 million hunting and fishing license holders.  The State Parks Department advised that the attack did not compromise social security numbers, dates of birth or financial information. Texas Cyber Command, the state’s new cybersecurity authority formed to protect critical infrastructure and coordinate threat responses across state and local government, reportedly assisted in detecting and containing the attack. TPWD has already set up free credit monitoring for those impacted through Kroll.  According to press reports, no specific group has yet been identified as the perpetrator of the theft. TPWD also advised that business has not been interrupted and license sales were continuing. This incident once again demonstrates that cybersecurity is only as strong as the weakest link in the supply chain. Businesses must prioritize security across their own environments and those of their vendors and contractors as well.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

The Enforceability of Online Arbitration Agreements Remains Unresolved in Pennsylvania, But the Pennsylvania Superior Court has Provided Substantive Guidance on the Issue

Key Points: The Pennsylvania Supreme Court confirms that an order compelling arbitration is not immediately appealable as collateral orders. The outcome of Chilutti II has generally left the substantive enforceability issues with browsewrap agreements unresolved in Pennsylvania. Until this issue is resolved by the Pennsylvania courts, companies operating in the Commonwealth should strive to ensure that their registration websites and/or application screens conspicuously present arbitration agreements in manners which ensure their users and consumers assent to the terms of the agreements by following the standards set forth in Chilutti I. Browsewrap agreements have been defined as agreements “‘in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website,’ and typically do not require an electronic signature.” See, Cobb v. Tesla, Inc., 2026 WL 458470, at *1 n. 2 (Pa. Super. Feb. 18, 2026) (citation omitted). They are largely regarded as the “if you keep using this, you agree to everything buried in this link” terms embedded into almost every online agreement consumers and users sign before proceeding with purchases of goods and/or services. While consumers are generally aware of them, many almost never click on the link, nor read them in their entirety. This leaves many consumers and users ignorant of the terms and impact of such agreements. However, one’s ignorance of the otherwise neatly-tucked-away terms rarely renders them unenforceable. The issue of the enforceability of browsewrap agreements has been up for debate for some time in many jurisdictions, including Pennsylvania. Indeed, Pennsylvania had a brief grip on this issue for a period in time. Specifically, in 2023, an en banc Superior Court set forth heightened standards for companies to meet in order to secure assent and enforce browsewrap arbitration agreements. See Chilutti v. Uber Techs., Inc., 300 A.3d 430 (Pa.Super. 2023) (en banc) (“Chilutti I”) Chilutti I involved a husband and wife who sued Uber and its subsidiaries after the wife, a wheelchair bound passenger using Uber’s rideshare service, fell, struck her head, and lost consciousness due to her uber driver failing to provide a seatbelt and making an aggressive turn during the trip. The Chilutti’s filed a negligence lawsuit against Uber and its subsidiaries. In response, the defendants moved to compel arbitration, arguing that “the couple’s conduct on the company’s website and application — when they registered for the ridesharing service — signified that they agreed to be bound by the mandatory arbitration provision found in the hyperlinked terms and conditions.” The trial court granted the defendants’ petition and stayed the proceedings pending the results of arbitration, and the Chilutti’s appealed. On appeal, the Superior Court addressed two issues. First, it addressed the issue of whether it had jurisdiction to hear the appeal. A divided Superior Court determined that it did, with its basis for the holding being that the order from which the Chilutti’s appealed was a collateral order. Next, the Superior Court set out to address the merits of the Chilutti’s substantive claim. The Superior Court concluded that the parties lacked a valid agreement to arbitrate. Its rationale was that Uber’s website and application did not provide reasonably conspicuous notice of the terms to the Chiluttis. In reaching this decision, the en banc Superior Court held that browsewrap arbitration agreements are enforceable in Pennsylvania only if the registration website and application screens explicitly inform consumers that they are waiving the right to a jury trial, the registration process cannot be completed until the consumer is fully informed of this waiver, and, when the agreement is available via hyperlink, the waiver appears at the top of the first page of the terms in bold, capitalized text. Since the ruling, Pennsylvania courts have applied Chilutti I to determine if browsewrap agreements are enforceable.  For instance, the Allegheny County Court of Common Pleas invoked Chilutti I to reject an agreement that lacked an express jury-trial waiver on the assent screen.  See Miller v. Festival Fun Parks, LLC, 92 WDA 2025 (C.P. Alleg. Cnty. Mar. 24, 2025). Similarly, the Superior Court has held that notice which failed to explicitly state the consumer was waiving a jury-trial right did not “me[e]t the strict burden set forth by our en banc Court in Chilutti I.” Pierce v. FloatMe Corp., 348 A.3d 1077, 1088 (Pa. Super. 2025). While the issue of enforceability of browsewrap agreements appeared to have been resolved by Chilutti I, Pennsylvania courts’ grip on this issue has been slackened by the Pennsylvania Supreme Court’s January 21, 2026, opinion in Chilutti II. See Chilutti v. Uber Techs., Inc., 349 A.3d 826 (Pa. 2026) (“Chilutti II”). Therein, the Supreme Court did not address the merits of the Chiluttis’ substantive claim, but rather the issue of whether the Superior Court had appellate jurisdiction to immediately review the orders staying litigation pending arbitration. The Court ultimately vacated the en banc opinion on jurisdictional grounds, holding that the Superior Court did not have appellate jurisdiction because the trial court’s order from which the Chiluttis appealed did not qualify as a collateral order and, thus, the Superior Court erred in holding to the contrary and lacked jurisdiction to entertain the merits” of the Chiluttis’ substantive claim. As such, Chilutti II has rendered Chilutti I nonbinding, and the issue of enforceability of online arbitration agreements remains unresolved. However, in light of the fact the Supreme Court did not address or comment on the merits of the Chiluttis’ appeal, Chilutti I is still meaningful. Specifically, it provides guidance as to the standards a company should strive to meet to ensure they have obtained users’ assent so that they are able to enforce online arbitration agreements. Additionally, it may serve as persuasive authority in judges’ evaluations of petitions and/or motions to compel browsewrap arbitration agreements until this particular issue is properly put before our appellate courts.

Summary Judgment Secured, Preserving $750,000 in Coverage for Insured in Major Trucking Liability Dispute

Ray Freudiger and Michael A. Roberts (both of Cincinnati) successfully obtained summary judgment on behalf of their client in a coverage dispute arising from a May 19, 2022, motor vehicle accident. A permissive driver operated a box truck for an interstate trucking company and caused severe injuries to two tort victims. Prior to the accident, the insured had procured a commercial auto policy for the trucking company with stated limits of $1,000,000. Following the accident, the insurer initiated a declaratory judgment action asserting that only reduced bodily injury limits of $25,000/$50,000 applied and later counterclaimed, alleging it would not have insured the driver had he been properly submitted for approval under the policy. After extensive discovery, briefing, and oral argument, the court rejected the insurer’s attempt to shift responsibility for the $750,000 in coverage it was legally required to provide for permissive drivers under Ohio law, granting summary judgment in favor of the insured and preserving $750,000 in liability exposure.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.
