Airworthiness Directive · Amendment 39-9067 · Honeywell International Inc. Engines
Honeywell International Inc. Engines
This AD applies to Honeywell International Inc. TFE731-3A, TFE731-3AR.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to AlliedSignal Inc., (formerly Garrett Engine Division) TFE731-3A-200G and -3AR-200G model turbofan engines. This action requires removing from service certain low pressure turbine (LPT) disks, imposing an hourly life limit on the first stage and second stage LPT disks, performing a dimensional inspection of second stage LPT disks at repetitive intervals, and incorporating honeycomb material in the second stage LPT nozzle air seal. This amendment is prompted by reports of LPT disk web separations. The actions specified in this AD are intended to prevent LPT disk web separations, which can result in an uncontained engine failure and damage to the aircraft.
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.
