Is AD 02-29003 a recurring Airworthiness Directive?

No — AD 02-29003 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 02-29003 apply to?

AD 02-29003 applies to Textron Lycoming — models AEIO-540, IO-540, LTIO-540, O-540, TIO-540. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes an emergency airworthiness directive (AD) that was sent previously to all known U.S. owners and operators of Textron Lycoming (T/L) AEIO-540, IO-540, LTIO-540, O-540, and TIO-540 series reciprocating engines. That action requires replacing certain zinc-plated crankshaft gear retaining bolts. This action still requires replacing certain zinc-plated crankshaft gear retaining bolts, but expands the population of affected engines. This amendment is prompted by two recent failures of zinc-plated crankshaft gear retaining bolts, and a reassessment of the extent to which the suspect bolts may still be present in the field. The actions specified by this AD are intended to prevent loss of all engine power and possible forced landing.

Part-conditional — STD-2209, 05K19987.

Applies to AEIO-540, IO-540, LTIO-540, O-540, and TIO-540 series engines with crankshaft gear retaining bolt P/N STD-2209 installed. Excludes O-540-F series engines subject to AD 99-03-05 whose bolt has not been replaced with one other than from gear bolt replacement kit 05K19987, and excludes engines with single-drive dual magnetos.

Whether AD 02-29003 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 02-29003 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.
