Is AD 2014-12-01 a recurring Airworthiness Directive?

Yes — AD 2014-12-01 requires a repetitive inspection every 10 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2014-12-01 apply to?

AD 2014-12-01 applies to Bell — models 214B, 214B-1, 214ST, 214. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are superseding Airworthiness Directive (AD) 2013-11-05 for Bell Model 214B, 214B-1, and 214ST helicopters with certain tail rotor hanger bearings (bearing) installed. AD 2013-11-05 required inspecting the bearing to determine whether an incorrectly manufactured seal material is installed on the bearing. This new AD retains the repetitive inspection of the bearings and also requires replacing the defective bearings. This AD was prompted by a report that certain bearings were manufactured with an incorrect seal material that does not meet Bell specifications. We are issuing this AD to prevent failure of the bearing and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 10 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Models214B, 214B-1, 214ST, 214

Serial-conditional — narrows to serials 28001–28070, 28101–28200.

Part-conditional — 214-040-606-005, 214-040-606-101.

214B and 214B-1 serial numbers 28001 through 28070; 214ST serial numbers 28101 through 28200. Applies only to helicopters with a tail rotor hanger bearing P/N 214-040-606-005 or 214-040-606-101 installed.

Whether AD 2014-12-01 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 2014-12-01 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.
