Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2016-11-21 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135T1, EC135T2, and EC135T2+ helicopters. AD 2016-11-21 required revising the life limit of certain parts and removing each part that has reached its life limit. This AD continues to require revising the life limits for certain parts and removing each part that has reached or exceeded its life limit and expands the applicability to include Model EC135P3 and EC135T3 helicopters. This AD was prompted by the certification of new helicopter models since AD 2016-11-21 was issued. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2021-11-22 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 2021-11-22 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.
