Airworthiness Directives; Fokker Model F28 Mark 0100 Series Airplanes

الملخص

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Fokker Model F28 Mark 0100 series airplanes. This proposal would require modification of a certain galley; repetitive inspections to detect damage and determine the clearance of generator wires in the auxiliary power unit (APU); and repair or replacement of the damaged wires. This proposal would also require an additional modification of a certain galley, which would terminate the repetitive inspection requirements. This proposal is prompted by reports that, during an unscheduled removal of a certain galley from the production line, the insulation of one of the generator wires of the APU was found damaged due to inadequate clearance with the adjacent structure. The actions specified by the proposed AD are intended to prevent such damage, which could result in a short in the electrical wiring of the APU and, thus, pose a potential fire hazard.
