Airworthiness Directives; AlliedSignal, Inc. TPE331 Series Turboprop and TSE331 Series Turboshaft Engines

This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal, Inc. (formerly Allied-Signal, Inc., Garrett Engine Division, Garrett Turbine Engine Company, and AiResearch Manufacturing Co. of Arizona) TPE331 series turboprop and TSE331 series turboshaft engines, that requires a record check of engine records to determine if any repair, assembly, modification, or installation work was performed by Fliteline Maintenance, formerly located in Wharton, Texas, or Mr. Eugene E. Shanks, or Mr. Carl Ramirez (collectively referred to as ``Fliteline''). In addition, for engines determined to have repair, assembly, modification, or installation work performed by Fliteline, this action requires verification of all life limited components, inspection of affected components, and verification of compliance with all applicable AD's. This amendment is prompted by the results of a Federal Aviation Administration (FAA) investigation involving engines repaired, assembled, modified, or installed by Fliteline. The actions specified by this AD are intended to prevent uncontained failure of turbine rotors, fire, or loss of aircraft control.
