Airworthiness Directive · Amendment 39-17363 · Landing gear retract/extend system
Eurocopter France Helicopters
This AD applies to Eurocopter Model AS332C, AS332L, and AS332L1 helicopters not modified per modification (MOD) 0723817, MOD 0725670, MOD 332P083218 or MOD 332A088381, with a main landing gear control panel (control panel) 33G, part number (P/N) 332A67-1623-00, -06, -0610, or -0651; certificated in any category.
We are adopting a new airworthiness directive (AD) for the Eurocopter France (Eurocopter) Model AS332C, AS332L, and AS332L1 helicopters. This AD requires modifying the main landing gear control panel (control panel) 33G, connector 100G, and wiring. It also requires tests to ensure that these modifications function correctly. This AD was prompted by reports of electro-valve power supply disruptions while a helicopter is on the ground, causing the landing gear to retract and the helicopter nose to drop. This results in damage to the forward section of the helicopter's bottom structure. The actions of this AD are intended to prevent an uncommanded landing gear retraction that would cause the helicopter nose to drop and hit the ground while the rotor blades are spinning.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Within 90 days, modify the control panel 33G and connector 100G, route the 1GA5103E wiring, and perform the tests in accordance with the Accomplishment Instructions, Paragraphs 2.B 2.a. through 2.B.3.d., and as depicted in figures 1 and 2, of Eurocopter Alert Service Bulletin No 32.00.18, Revision 2, dated July 12, 2010.
