Airworthiness Directive 2020-05-23
one-timeAirworthiness Directives; Airbus Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD requires inspecting the attachment screws of each main gearbox (MGB) suspension bar rear attachment fitting, and depending on the outcome, applying a sealing compound, performing further inspections, and replacing affected parts. This AD was prompted by reports of an elongated attachment screw and loss of tightening torque of the nut. The actions of this AD are intended to address an unsafe condition on these products.
Which aircraft AD 2020-05-23 applies to
Applies only to helicopters delivered to the first owner or customer before September 1, 2018, with attachment screws P/N 330A22013520 installed with MGB right-hand side rear attachment fitting P/N 330A22270207 and left-hand side rear attachment fitting P/N 330A22270206 of the MGB suspension bars.
Whether AD 2020-05-23 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
