Airworthiness Directives; Fokker Services B.V. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F.27 Mark 050 airplanes. This proposed AD would require performing a low frequency eddy current inspection for cracks of the lap joint of the rear fuselage, and repair if necessary. This AD was prompted by reports of cracking in the fuselage lap joint. We are issuing this AD to detect and correct exponential crack growth, which could lead to failure of the lap joint over a certain length and consequent in-flight decompression of the airplane.

Whether AD 2012-07-05 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 2012-07-05 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.
