Airworthiness Directive · Amendment 39-17184 · Engine controls
Eurocopter France Helicopters
This AD applies to Model SA330F, SA330G, SA330J, AS332C, AS332L, AS332L1, and AS332L2 helicopters, certificated in any category.
We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model SA330F, SA330G, SA330J, AS332C, AS332L, AS332L1, and AS332L2 helicopters to require cleaning, inspecting, and lubricating each tangential gearbox (gearbox) and adjusting, as necessary, the fuel shut-off control lever. This AD was prompted by the jamming of one of two fuel shut-off control levers because of solidified grease in the gearbox. A companion gearbox had extensive corrosion. In case of an emergency, pilots may need to use the control levers to shut off fuel going into the engine and to shut off the helicopter's electrical power system. The jamming of the levers prevents the shut off of the engine fuel and prevents the parallel- mounted micro switches from switching off the electrical power system. These actions are intended to prevent the jamming of the control levers, which could prevent shut-off of the engine fuel and electrical power system during an emergency shutdown.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Within 50 hours time-in-service, clean, inspect, and lubricate each gearbox and adjust, as necessary, the fuel shut-off control lever by following the Accomplishment Instructions, Paragraph 2.B.2 (reference Figures 3 through 7), of Eurocopter Alert Service Bulletin (ASB) No. 76.03, Revision 1, dated March 22, 2007, for the Model SA330F, SA330G, and SA330J helicopters, or ASB No. 76.00.04, Revision 1, dated March 22, 2007, for the Model AS332C, AS332L, AS332L1, and AS332L2 helicopters.
