FAA Proposes $60,000 Fine Against Lycoming Engines Over Alleged Maintenance Violations on Four TEO-540-C1A Engines
Why It MattersThe case highlights continued FAA scrutiny of repair-station compliance with manufacturer maintenance manuals for piston-engine servicing before return to service.
The Federal Aviation Administration has proposed a $60,000 civil penalty against Lycoming Engines over alleged violations of federal maintenance regulations tied to work performed in September 2024 on four Lycoming TEO-540-C1A engines at the company's aircraft repair station. The FAA alleges that Lycoming's repair station failed to follow the manufacturer's maintenance manual during servicing, specifically by not replacing the Exhaust Bypass Valve Assemblies on the four engines as required before returning them to service.
Lycoming Engines has 30 days to respond to the FAA's enforcement letter and has not issued any public statement regarding the proposed fine or the specific allegations.
