Model 209 Digital Flight Data Recorders installed in, but not limited to, Boeing 727, 737 and 747, Douglas DC-8, DC-9, and DC-10, Lockheed L-1011, Dassault/Sud Fan Jet Falcon, Hawker-Siddeley DH-125 and 748, and Fokker F-28 airplanes, and Boeing-Vertol 114A (U.S. Army CH-47A) helicopters, certificated in all categories.

Whether AD 75-08-17 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 75-08-17 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.
