Airworthiness Directives; AlliedSignal, Inc. LTS101-600 Series Turboshaft Engines

概要

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to AlliedSignal, Inc. LTS101-600 series turboshaft engines. This proposal would require installation of an improved design fuel control. This proposal is prompted by reports of fuel control bearings failing prior to the recommended overhaul period. The actions specified by the proposed AD are intended to prevent a fuel control failure, which could result in an uncommanded increase or decrease in engine power.
