Is AD 97-12517 a recurring Airworthiness Directive?

No — AD 97-12517 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 97-12517 apply to?

AD 97-12517 applies to Fairchild — models SA226, SA227. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes Airworthiness Directive (AD) 96-21- 05, which currently requires the following on certain Fairchild Aircraft, Inc. (Fairchild) SA226 and SA227 series airplanes that do not have a certain elevator torque tube installed: drilling inspection access holes in the elevator torque tube arm, inspecting the elevator torque tube for corrosion, replacing any corroded elevator torque tube, and applying a corrosion preventive compound. AD 96-21-05 resulted from several reports of corrosion found in the elevator torque tube area on the affected airplanes. This AD retains the actions required by AD 96- 21-05, and adds certain Fairchild Model SA227-BC airplanes to the Applicability section of that AD. The actions specified by this AD are intended to prevent failure of the flight control system caused by a corroded elevator torque tube, which could result in loss of control of the airplane.

Whether AD 97-12517 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.
