## Summary

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 a visual inspection to detect damage to the flexible fuel drain line of the auxiliary power unit (APU), and replacement of the drain line, if necessary. This proposal also would require installation of two additional clamps to secure the flexible fuel drain line to the fuel supply line of the APU. This proposal is prompted by reports of electrical arcing between the flexible fuel drain line and the APU starter motor. The actions specified by the proposed AD are intended to prevent such electrical arcing, which could result in a fire in the APU.
