Airworthiness Directive · Amendment 39-12786 · Eurocopter France Model SA330F, G, J, and AS332C, L, and L1 Helicopters
Eurocopter France Model SA330F, G, J, and AS332C, L, and L1 Helicopters
Model SA330F and G helicopters with a Multi-Purpose Air Intake (MPAI) installed; Model SA330J helicopters with an MPAI installed and not modified by either MOD 0723672 in accordance with Eurocopter Service Bulletin No. 30.16, Revision 1, dated February 3, 2000, or MOD 0725920 in accordance with Eurocopter Service Bulletin No. 30.17, dated February 3, 2000; and Model AS332C, L, and L1 helicopters with an MPAI installed and not modified by either MOD 0725885 in accordance with Eurocopter Service Bulletin No. 30.00.44, Revision 1, dated July 12, 1999, or MOD 0725974 and MOD 0725998 in accordance with Eurocopter Service Bulletin No. 30.00.46, dated July 12, 1999, certificated in any category.
This amendment supersedes an existing airworthiness directive (AD) for specified Eurocopter France (ECF) model helicopters that currently requires inserting statements into the Limitations section of the Rotorcraft Flight Manual (RFM) prohibiting flight under certain atmospheric conditions. This amendment contains the same requirements but corrects, expands, and updates the applicability. This amendment is prompted by an 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 by 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.
