The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
