## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to MD Helicopters Inc. (MDHI) Model MD600N helicopters, that requires inspecting each internal fuel hose connection to verify proper installation. This amendment is prompted by the discovery that certain fuel hose connections between the fuel cells and the engine can be incorrectly installed. The actions specified by this AD are intended to prevent fuel starvation of the engine while the fuel gage indicates fuel remaining in the tank, engine flameout, and a subsequent forced landing.
