## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires replacement of the lighting plates of the fuel control panel and the electrical power control panel with new, improved lighting plates. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent internal short circuits in the fuel control and electrical power control panels, which could result in burning of the panels and consequent smoke in the flight deck area.
