AD text lists specific serial numbers per model (e.g. 310R S/N 1865; 335 S/N 0044,0049,0052,0059; 340A multiple discrete S/N) rather than a contiguous range — exact serials must be confirmed from the AD text, not inferred as a range (applicability read from the AD teaser — confirm exact model/serial from the records.)

Whether AD 80-13-14 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 80-13-14 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.
