FAA Proposes Airworthiness Directive for Honeywell TFE731-2C Engines

Summary

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for Honeywell International Inc.'s TFE731-2C series turbofan engines, requiring removal from service of certain high-pressure turbine rotor assemblies and returning them to Honeywell for inspection due to improperly machined radii in the root of the forward and aft curvic teeth during manufacture.
