Is AD 01-25397 a recurring Airworthiness Directive?

No — AD 01-25397 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 01-25397 apply to?

AD 01-25397 applies to Fairchild — models SA226, SA227. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Fairchild Aircraft, Inc., Models SA226 and SA227 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain Fairchild Aircraft SA226 and SA227 series airplanes. This AD requires you to replace the brake shuttle valves with parts of improved design and install a shield over the hydraulic lines. This AD also requires replacing the rubber fuel hose with a metal device for certain SA226 series airplanes. This AD is the result of a report of a wheel brake system malfunction caused by a faulty brake shuttle valve. The actions specified by this AD are intended to correct potential brake shuttle valve problems, which could cause the brake assembly to drag and overheat. Hydraulic or fuel line damage could then occur if the overheated brake assembly is retracted into the main wheel well, with a consequent fire if the hydraulic or fuel lines ruptured.

Whether AD 01-25397 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 01-25397 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.
