Airworthiness Directive 2026-05-06
one-timeAirworthiness Directives; Airbus Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and SA330J helicopters. This AD was prompted by reports of fatigue cracks found on arms of the tail rotor (TR) pitch change spider due to a load increase originating from degraded bearing stacks. This AD requires reduced life limit intervals for the affected bearing stack and requires replacing the affected bearing stack before exceeding these intervals. This AD also prohibits the installation of the affected bearing stack on a helicopter, unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-05-06 applies to
Whether AD 2026-05-06 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.
