Airworthiness Directive · Amendment 39-13172 · Eurocopter France Model AS332C, L, and L1 Helicopters
Eurocopter France Model AS332C, L, and L1 Helicopters
Model AS332C, L, and L1 helicopters with an elbow adapter (adapter), part number (P/N) DHS613-636-43, with a manufacturing code on the hydraulic reservoir end indicating manufacture before January 1, 2002, and not identified by a yellow paint mark, installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This action requires replacing a certain elbow adapter (adapter) with an airworthy adapter. This amendment is prompted by reports of a cracked adapter on the hydraulic reservoir resulting in leakage of hydraulic fluid and loss of hydraulic power. This condition, if not corrected, could result in failure of an adapter on the hydraulic reservoir, loss of hydraulic fluid, loss of hydraulic power, and subsequent loss of control of the helicopter.
