Is AD 2009-19-06 a recurring Airworthiness Directive?

Yes — AD 2009-19-06 requires a repetitive inspection every 50 hours. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2009-19-06

Q: Which aircraft does AD 2009-19-06 apply to?

AD 2009-19-06 applies to Teledyne Continental Motors — models O-470-G, O-470-K, O-470-L, O-470-R, O-470-S, O-470-M, O-470-U, IO-470-C. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Teledyne Continental Motors O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 Series Reciprocating Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Teledyne Continental Motors (TCM) O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 series reciprocating engines with TCM EQ3 cylinders installed. This AD requires initial and repetitive visual inspections of TCM EQ3 cylinders for cracks. This AD also requires removal of all EQ3 cylinders as terminating action to the repetitive visual inspections. This AD results from reports of 35 EQ3 cylinders found cracked. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder head, possible engine failure, and fire in the engine compartment.

Repetitive inspection. Re-inspect every 50 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies only to engines with one or more affected TCM EQ3 cylinders installed, identified by cross-referencing the engine models with the engine serial numbers found in Tables 1, 1A, 2, and 2A of TCM Mandatory Service Bulletin (MSB) No. MSB09-1B, dated July 14, 2009; also applies to spare EQ3 cylinders identified by cylinder part number and serial number per the same MSB.

Whether AD 2009-19-06 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 2009-19-06 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.
