Airworthiness Directives; Raytheon (Beech) Model 400A Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A airplanes, that requires replacement of the fuel drain tube assembly in the aft fuselage with a new, modified assembly. This amendment is prompted by a report of chafing of the fuel tube assembly against the elevator control cable due to inadequate clearance between the components. The actions specified by this AD are intended to prevent chafing of the fuel drain tube assembly, which could result in fuel leakage from the fuel drain tube assembly and consequent risk of a fire.
