Summary
We propose to adopt a new airworthiness directive (AD) for Eurocopter (Eurocopter) France Model EC225LP helicopters. This proposed AD would require measuring the operating load of the cockpit fuel shut- off controls and replacing the tangential gearbox if the operating load threshold is exceeded. This proposed AD is prompted by the jamming of the left-hand (LH) side of the fuel shut-off and general cut-off controls (controls). The proposed actions are intended to prevent the jamming of the controls so that a pilot can shut down an engine during an engine fire or during an emergency landing.
