Airworthiness Directives; Fokker Model F28 Mark 0100 Series Airplanes

Riepilogo

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes, that requires 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 amendment also requires installation of two additional clamps to secure the flexible fuel drain line to the fuel supply line of the APU. This amendment is prompted by reports of electrical arcing between the flexible fuel drain line and the APU starter motor. The actions specified by this AD are intended to prevent such electrical arcing, which could result in a fire in the APU.
