Lycoming Engines Engines
Superseded. A later AD replaced this one: AD 71-13-01 R1. Comply with the one in force.

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 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.
