Is AD 2008-20-03 a recurring Airworthiness Directive?

Yes — AD 2008-20-03 requires a repetitive inspection every 3 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2008-20-03 apply to?

AD 2008-20-03 applies to Fokker — models F.28 Mark 0070, F.28 Mark 0100, F.28. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Fokker Model F.28 Mark 0070 and Mark 0100 Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. That AD currently requires a one-time inspection of the main landing gear (MLG) main fitting for cracks, and repair if necessary. The existing AD also currently requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This new AD requires repetitive eddy current inspections of the MLG main fitting and rework before further flight as applicable. This AD results from reports that a final solution eliminating the cause of the crack initiation mechanism is not yet available and that repetitive inspections are necessary. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.

Repetitive inspection. Re-inspect every 3 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies only to airplanes equipped with Messier-Dowty main landing gears (MLGs).

Whether AD 2008-20-03 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 2008-20-03 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.
