## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model BAe 125-800A series airplanes and Hawker 800 series airplanes, that requires a detailed visual inspection of the fuel feed hose assemblies of the auxiliary power unit (APU) to detect overheating, degradation, proper routing, and adequate clearance; and the correction of any discrepancies found. This amendment also requires modification of the fuel feed hose of the APU. This amendment is prompted by reports of heat damage to the fuel feed hose assembly of the APU due to contact between the hose assembly and hot surfaces. The actions specified by this AD are intended to prevent heat damage of the fuel feed hose, which could lead to a possible fire/ smoke hazard when failure of the hose assembly occurs and consequent fuel mist or spray is emitted into the rear equipment bay.
