Airworthiness Directive 2021-20-03
one-timeAirworthiness Directives; Leonardo S.p.a. Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by reports of in-flight pilot collective stick oscillation. This AD requires a one-time measurement of the friction of the pilot collective stick assembly to verify that it is within the allowable range and, depending on findings, making an adjustment to restore the acceptable level of friction, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2021-20-03 applies to
Applies only when the affected part identified in EASA AD 2018-0203, dated September 12, 2018, is installed.
Whether AD 2021-20-03 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.
