Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters

We propose to adopt a new airworthiness directive (AD) for the Eurocopter Model SA330F, G, J and AS332C, L, L1, and L2 helicopters. This proposed AD is prompted by two reports of jamming of one of the fuel shut-off control levers, which originated from solidified grease in the tangential gearbox (gearbox). Corrosion was also found in a gearbox. The proposed actions are intended to prevent jamming of a fuel shut-off control lever preventing the shut off of engine fuel and preventing the parallel-mounted electrical micro switches, normally activated by shutting off both of the fuel shut-off control levers, from switching off the electrical power system during an emergency shut down.
