## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB 340B and SAAB 2000 series airplanes. This action requires an inspection of the fluorescent lamps in the cabin area to ensure correct installation, and correction, if necessary. This AD also requires an inspection of the lampholders to identify any discrepancies and to ensure the security of the back covers, and replacement of discrepant lampholders with new lampholders; installation of retaining clips on certain Page Aerospace lampholders; and reinspection of the lamps to ensure correct installation after replacement or reinstallation of the lamps or lampholders, and corrections, if necessary. This amendment is prompted by reports indicating that loose back covers on the lampholders and incorrect lamp installations have led to electrical arcing between fluorescent tube pins and lampholders and consequent charring or melting of the affected areas. The actions specified in this AD are intended to prevent such electrical arcing, which could burn the surrounding area and lead to smoke and fumes in the passenger compartment or lavatory area.
