Airworthiness Directive · Amendment 39-11168 · Eurocopter France Model AS332L2
Eurocopter France Model AS332L2
AS332L2 helicopters, with main rotor head drag damper, part number (P/N) 332A311980-02, having elastomeric bearings P/N J19084-4, installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to AS332L2 helicopters. This action requires inspecting each main rotor head drag damper (damper) for a tear, crack, or bonding separation in the elastomer and, if necessary, replacing the damper with an airworthy damper. This amendment is prompted by a report of increased helicopter vibration in flight that was traced to the delamination of the elastomer on a damper. This condition, if not corrected, could result in failure of a damper and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
