MakesSaab-Fairchild
ModelsSF340

To prevent engine control cable freezing, modify the engine control cable system per Saab-Fairchild Service Bulletin SF340-76-007, Revision 3, dated August 14, 1985; compliance within 60 days after the effective date unless previously accomplished. Applies to aircraft certificated in any category.

Whether AD 86-18-07 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 86-18-07 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.
