Is AD 01-22086 a recurring Airworthiness Directive?

No — AD 01-22086 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 01-22086 apply to?

AD 01-22086 applies to Fokker — models 200, 300, 400, 500, 600, 700. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 series airplanes, that requires a one-time inspection for correct installation of the left- and right-hand fuel differential pressure (FDP) switches and for correct connection of the pressure sensing lines to the switches, and corrective action, if necessary. The actions specified by this AD are intended to ensure that a warning light goes on when the fuel filter is partially blocked by ice, so that the blockage of the fuel filter does not increase, leading to reduced fuel flow to the engine and possibly to an engine flame-out. This action is intended to address the identified unsafe condition.

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

Whether AD 01-22086 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 01-22086 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.
