The New Piper Aircraft, Inc. Models PA- 46-310P and PA-46-350P Airplanes
Superseded. A later AD replaced this one: AD 99-15-04 R1. Comply with the one in force.
Models PA-46-310P and PA-46-350P airplanes, all serial numbers, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to all The New Piper Aircraft, Inc. (Piper) Models PA-46-310P and PA-46-350P airplanes. This AD requires calibrating the turbine inlet temperature system to assure the accuracy of the existing turbine inlet temperature indicator and wiring for all of the applicable airplanes, and repairing or replacing any turbine inlet temperature system that fails the calibration test. This AD also requires repetitively replacing the turbine inlet temperature probe on the Model PA-46-350P airplanes, and inserting a copy of this AD into the Pilot's Operating Handbook of certain airplanes. This AD is the result of field reports that indicate service accuracy problems with the existing turbine inlet temperature system. The actions specified by this AD are intended to prevent improper engine operation caused by improperly calibrated turbine inlet temperature indicators or defective turbine inlet temperature probes, which could result in engine damage/failure with consequent loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
