Full official abstract

This amendment adopts a new airworthiness directive (AD), that is applicable to Honeywell International Inc. (formerly AlliedSignal Inc. and Textron Lycoming) Models LTS101-600A-2 and LTS101-600A-3 turboshaft engines; and LTP101-600A-1A and LTP101-700A-1A turboprop engines. This amendment requires replacing certain fuel controls that have beryllium-copper bellows with improved fuel controls that incorporate Inconel 718 stainless steel welded bellows. This amendment is prompted by a report of an uncommanded power loss on a Textron Lycoming LTS101 engine due to a corrosion damaged fuel control bellows. The actions specified by this AD are intended to prevent the engine from reducing the fuel flow to minimum flow resulting in an uncommanded power loss.
