Airworthiness Directives; Eurocopter France Model SA330F, G, J, and AS332C, L, and L1 Helicopters

요약

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Eurocopter France Model SA330F, G, J, and AS332C, L, and L1 helicopters. This action requires inserting statements into the Limitations section of the Rotorcraft Flight Manual (RFM) prohibiting flight under certain atmospheric conditions. This amendment is prompted by one incident in which a Multi-Purpose Air Intake (MPAI) inlet seal deflated after the P2 air system line, which feeds the seal, clogged due to the formation of ice. The actions specified in this AD are intended to prevent clogging of the MPAI seal P2 air system line due to ice formation, which could result in deflation of the MPAI seal, loss of engine power, and subsequent loss of control of the helicopter.
