Business jet operators should take action to preserve their engines if the aircraft is going to sit idle for more than two or three months, according to recommendations from engine makers. Such preventive measures can be as easy as ensuring oil is coating components properly or as complicated as removing and bagging the engines. Neglecting an engine that sits inactive for a protracted period can cause serious problems that are not covered by a maintenance plan.

Moisture in the fuel or engine oil can attack the bare metal surfaces inside the engine, beginning corrosion in bearings and gears, Mike Bevans, Honeywell’s director of technical sales, told AIN. A Pratt & Whitney Canada spokesperson said that corrosion can set in within “as little as 24 to 48 hours.”
