Is AD 01-22085 a recurring Airworthiness Directive?

No — AD 01-22085 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 01-22085 apply to?

AD 01-22085 applies to Fokker — models 2000, 3000, 4000. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes, that requires a one-time eddy current inspection for cracks of the fuselage butt joint which is forward of the emergency exits on the left- and right-hand sides of the airplane at the level of stringers 27/48. This proposal would also require repair of any cracks detected. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign airworthiness authority. The actions specified by this AD are intended to detect and correct cracks in the area of the emergency escape hatches, which, if undetected, could result in depressurization during flight, possibly leading to structural failure of the airplane.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 01-22085 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 01-22085 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.
