Airworthiness Directives; Textron Lycoming LTS101 Series Turboshaft and LTP101 Series Turboprop Engines

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that is applicable to Textron Lycoming LTS101 series turboshaft and LTP101 series turboprop engines. This action requires a one-time removal of 321 No. 2 bearings with serial numbers from suspect manufacturing lots, and replacement with serviceable parts. This amendment is prompted by reports of three in-service bearing failures. The actions specified in this AD are intended to prevent engine power loss and inflight engine shutdown due to No. 2 bearing failure, which could result in possible loss of the aircraft.
