Lieff Cabraser; Epps, Holloway; CohenMalad; Wagstaff & Cartmell; and Morgan & Morgan Announce Filing of Class Action Against Textron Aviation Over Alleged Cessna CJ4 Aircraft Corrosion Defect

JCC Transport, LLC and CBP Air Logistics, LLC allege that all Textron Cessna Citation CJ4 Aircraft have a dangerous, uniform defect that can cost as much as $500,000 or more to repair properly.

On September 2, 2025, Lieff Cabraser Heimann & Bernstein, LLP; Epps, Holloway, Deloach & Hoipkemier, LLC; CohenMalad LLP; Wagstaff & Cartmell, LLP; and Morgan & Morgan, P.A. jointly filed a class action complaint in the United States District Court of Kansas against Textron Aviation, Inc. (“Textron”) alleging that a uniform defect leads to corrosion of the structural components of Textron’s Cessna Citation CJ4 aircraft, particularly the frames of the windshield and cockpit windows. If left unchecked, the corrosion caused by the defect can cause the plane to become unairworthy and potentially lead to catastrophic failure.

In April of 2024, Textron issued a service bulletin (SB525C-56-01), recommending that all CJ4 aircraft be inspected and, if necessary, repaired due to a condition in the window frames that causes “moisture incursion.” To date, however, Textron has not acknowledged that this “moisture incursion” is caused by a common defect present in all CJ4 aircraft. Nor has Textron warned owners of the significant potential safety risks the corrosion poses. The Complaint alleges that Textron is charging owners and lessees hundreds of thousands of dollars for repairs rather than covering the full cost to fully address the defect.

“This lawsuit is not just about protecting the owners and lessees of Cessna CJ4 Aircraft; it is about protecting the families, businesses, and crew that depend on these planes daily for safe travel,” notes Epps Holloway, Deloach & Hoipkemier, LLC partner Kevin Epps. “Textron Aviation is understating the actual costs to address the damage caused by this defect, while minimizing the danger every passenger of a CJ4 faces.”

“Preliminary expert analysis by an aerospace engineering expert has determined that this corrosion is the result of either a defective design or manufacturing process,” notes Lieff Cabraser senior partner Jonathan Selbin, another of the lead attorneys representing plaintiffs in the case. “It occurs when the aircraft is maintained in accordance with the aircraft’s maintenance manual and all applicable FAA standards; it is not related to the actions of any Cessna CJ4 owner.” Selbin continued, “We believe Textron needs to do right by all of their customers, warn them of the danger, and fix this problem at no cost to them before someone is hurt.”
