Requires operators of specified AlliedSignal TPE331 engines to check maintenance records for work done or released by Fliteline Maintenance (Houston) or the named mechanics, then inspect those engines — including disassembly where records show extensive work — to verify life‑limited parts, compliance with airworthiness directives and that installations follow approved data. Unverified life‑limited parts must be removed. The directive responds to FAA findings that some maintenance actions and record‑keeping by Fliteline may have been incomplete or inaccurate.

(a) If records or other pertinent information indicates the engine was disassembled beyond shaft nut removal from the rotor tie bolt by Fliteline Maintenance or Eugene Shanks or Carl Ramirez, verify life limited components status by the disassembly of the engine and compare and match each component by part number and serial number against that engine's life- limit records. If life-limited component hours and/or cycles cannot be validated, the component shall be removed from service.

(b) Verify the requirements of any airworthiness directive certified by Fliteline Maintenance or Eugene Shanks or Carl Ramirez have been carried out by visual examination or reinspection in accordance with the applicable airworthiness directive.
