Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 helicopters. This AD was prompted by reports of excessively worn bolts that connect the cardan-pivot joint with the piston rod of the tail rotor actuator (TRA) assembly. This AD requires repetitively inspecting certain TRA assemblies, and depending on the results, replacing or repairing parts, or accomplishing additional inspections. This AD also prohibits installing an affected TRA assembly unless it passes required inspections. Lastly, this AD provides terminating actions for certain inspections, as specified in a 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.

Repetitive inspection. Re-inspect every 330 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Helicopters with an MBB-BK 117 C-2(e) designation are considered Model MBB-BK 117 C-2 helicopters for purposes of this AD.

Whether AD 2022-21884 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2022-21884 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
