What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2020-11- 05, which applied to all Airbus Helicopters Model EC120B helicopters. AD 2020-11-05 required repetitive inspections of the tail rotor (TR) hub body for cracks and applicable corrective actions if necessary, and repetitive replacement of the attachment bolts, washers, and nuts of the TR hub body. This AD was prompted by a report of recurrent loss of tightening torque on several attachment bolts on the TR hub body. This AD retains certain requirements of AD 2020-11-05, adds repetitive inspections, requires additional corrective actions, and updates applicable service information. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 1000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to all serial numbers.

Whether AD 2021-26-07 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 2021-26-07 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.
