Is AD 2014-15-01 a recurring Airworthiness Directive?

Yes — AD 2014-15-01 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2014-15-01

Q: Which aircraft does AD 2014-15-01 apply to?

AD 2014-15-01 applies to M7 Aerospace — models SA227-AT, SA227-AC, SA227-BC, SA227-CC, SA227-DC, SA227. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; M7 Aerospace LLC Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for M7 Aerospace LLC Models SA227-AT, SA227-AC, SA227-BC, SA227-CC, and SA227- DC airplanes equipped with a bayonet shear pin main cabin door latching mechanism. This AD was prompted by fatigue cracks found in the internal door surround doubler, the fuselage external skin, and the door corner fittings at the fuselage upper forward corner of the main cabin door cutout. This AD requires repetitively inspecting the four corners of the main cabin door cutout for cracks, making necessary repairs, and reporting inspection results to M7 Aerospace LLC. We are issuing this AD to correct the unsafe condition on these products.

Repetitive inspection. Re-inspect. 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 AT570–AT631, AT695–AT695, AC570–AC788, BC762–BC762, BC764–BC764, BC766–BC766, BC770–BC789, CC827–CC827, CC829–CC829, CC840–CC844, DC784–DC784, DC790–DC826, DC828–DC828, DC830–DC839, DC845–DC904.

Applies only to airplanes equipped with a bayonet shear pin main cabin door latching mechanism; airplanes equipped with a 'click-clack' main cabin door latching mechanism are not affected by this AD. See M7 Aerospace SB CC7-53-005 and SB 227-53-009 (both dated November 15, 2013) for illustrations of both latching mechanism styles.

Whether AD 2014-15-01 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.

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.
