Airworthiness Directives; Raytheon Model Hawker 800XP Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Hawker 800XP series airplanes, that requires replacement of the fuel feed hose assemblies of the auxiliary power unit (APU) with new hose assemblies. This amendment is prompted by a report of the collapse of the inner casing of the fuel feed hose that supplies fuel to the APU. The actions specified by this AD are intended to prevent failure of the fuel feed hose assemblies, which could result in fuel leakage and consequent risk of fire in the aft equipment bay.
