Airworthiness Directive · Amendment 39-10052 · Saab Model SAAB 340B and SAAB 2000 Series Airplanes
Saab Model SAAB 340B and SAAB 2000 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-16-09. Comply with the one in force.
Model SAAB 340B series airplanes, having serial numbers -342 and -359 through -439 inclusive; and SAAB 2000 series airplanes, having serial numbers -004 through -059 inclusive; certificated in any category.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
