FAA Proposes Revision to Airworthiness Directive for Piper Aircraft Models PA-46-310P and PA-46-350P

Summary

The Federal Aviation Administration (FAA) proposes to revise an existing airworthiness directive (AD) for The New Piper Aircraft, Inc. Models PA-46-310P and PA-46-350P airplanes, which requires calibration and repair/replacement of the turbine inlet temperature system to ensure accurate engine operation. The proposed AD restricts applicability to airplanes where the factory-installed gauge and probe have been replaced through a supplemental type certificate (STC).
