All Lycoming opposed series aircraft engines.


During periodic inspection of the engine.

It has been determined that careful inspection and maintenance at precise, specified intervals will contribute immeasurably to the life of the engine and the avoidance of eventual damage or failure of the engine. It is the purpose of this instruction to point out items for inspection that are areas of extreme importance in detecting symptoms of abnormal engine condition; that is, conditions that if left uncorrected will eventually result in shortened engine life or actual engine failure.
