Overview

• The class-action complaint, filed September 26 in the Southern District of Florida, names General Electric, GE Aerospace, Bombardier, Learjet, Duncan Aviation, and Turbine Engine Specialists.
• Plaintiffs allege hidden corrosion in the CF34 variable guide vane system caused a non-recoverable dual compressor stall and that GE knew of the risk but failed to warn operators or fully cover corrosion in service contracts.
• The suit cites earlier CF34 events and service bulletins dating back to 2018 and 2021 that plaintiffs say did not adequately reach business-jet operators.
• Court orders allow Duncan Aviation to respond by October 8, GE Aerospace by October 14, and General Electric by November 24, with other responses also staggered.
• The NTSB’s probe continues after preliminary findings of corrosion in multiple engine components, and GE Aerospace and Bombardier have offered condolences and said they are cooperating with investigators.
