AD 95-08-10 60 FR 32581

This document publishes in the Federal Register Airworthiness Directive (AD) 95-08-10 that was sent previously to all known U.S. owners and operators of Teledyne Continental Motors (TCM) Model TSIO- 360 E, EB, F, FB, G, GB, KB, LB, MB, and Model LTSIO-360 E, EB, and KB reciprocating engines by individual letters. This AD requires replacement of the suspect turbocharger check valves prior to further flight, and prohibits special flight permits. This amendment is prompted by three reported engine failures caused by incorrectly assembled turbocharger oil outlet check valves, resulting in an improperly expanded rivet that held the check valve flapper assembly together as one unit. The actions specified by this AD are intended to prevent complete engine failure due to an incorrectly assembled turbocharger oil outlet check valve.
