Which aircraft AD 51-09-03 applies to

MakesTaylorcraft
Applies to all models of the make above.
Serial-conditional — narrows to serials ?–13001.
Part-conditional — B12-947-3.

Applies to all series aircraft below serial number 13001 incorporating a push-pull type fuel shutoff control. Compliance required not later than June 1, 1951. Requires modifying the shutoff valve to require a definite and positive movement by the pilot before it can be operated; Taylorcraft P/N B12-947-3 or equivalent is considered satisfactory.

Whether AD 51-09-03 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 51-09-03 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.
