Is AD 2012-22-11 a recurring Airworthiness Directive?

Yes — AD 2012-22-11 requires a repetitive inspection every 100 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2012-22-11 apply to?

AD 2012-22-11 applies to Bell — models 412, 412EP, 412CF. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Bell Helicopter Textron Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron (BHT) Model 412, 412EP, and 412CF helicopters. This AD requires a repetitive inspection of the collective lever for a crack, and if there is a crack, before further flight, replacing the collective lever with an airworthy collective lever. This AD was prompted by a reported failure of a collective lever. The actions are intended to detect a crack in the collective lever, which could lead to failure of the collective lever and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 100 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Serial-conditional — narrows to serials 33001–33213, 34001–34036, 36001–?, 46400–?.

Part-conditional — 412-010-408-101.

Serial ranges: Model 412 and 412EP - S/N 33001 through 33213, 34001 through 34036, and 36001 and higher. Model 412CF - S/N 46400 and higher. Applies only when collective lever P/N 412-010-408-101 is installed.

Whether AD 2012-22-11 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 2012-22-11 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.
