MODELS AFFECTED

I. All Textron Lycoming TIO-540-AJ1A and IO-540-AC1A5 aircraft engines shipped from the factory before October 30, 2000, unless Kit P/N 05K23081 has been installed.

TIME OF COMPLIANCE

I. Inspect within the next 10 hours of operation and replace within the next 50 hours of operation.

It has been determined that the existing oil filler tube installation could allow the clamp holding the tube to exert downward stress. This could result in damage to the filler tube.
