Airworthiness Directive · Amendment 39-13180 · Eurocopter France Model AS332 C, L, and L1 Helicopters
Eurocopter France Model AS332 C, L, and L1 Helicopters
AS332 C, L, and L1 helicopters, certificated in any category, with Turbomecca Makila 1A or Makila 1A1 engines installed with fuel control unit (FCU), part number (P/N) 0 164 16 820 0 or P/N 0 164 16 835 0, having serial numbers (S/N) 100 through 525, with a suffix of "M", except: (1) FCUs with S/N 168M, 323M, 369M, 371M, 378M, 382M, 396M, 407M, 422M, 445M, 449M, 460M, 469M, 472M, 479M, 488M, 499M, 513M, 518M, 523M; or (2) FCUs that have been tested and found to provide the correct fuel flow rate in accordance with Turbomeca Service Bulletin No. 298 73 0802, dated September 17, 2002.
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332 C, L, and L1 helicopters. This action requires revising the Rotorcraft Flight Manual (RFM) Limitations section if certain fuel control units are installed. This AD is prompted by the discovery of an anomaly in certain fuel control units that may lead to inadequate fuel flow in single-engine flight. This condition, if not corrected, could result in failure of the engine to develop the maximum 2\1/2\ minute one engine inoperative (OEI) power, reduced helicopter performance, and subsequent loss of control of the helicopter during OEI operation.
