de Havilland Model DHC-8-102, -103, and -301 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-23-27. Comply with the one in force.
Model DHC-8-102, -103, and -301 series airplanes; serial numbers 002 though 010 inclusive, 012 through 201 inclusive, 203 through 209 inclusive, 211 through 215 inclusive, 217 through 220 inclusive, 222, and 223; on which de Havilland Modification 8/ 1114 or 8/1110 (reference de Havilland Service Bulletin S.B. 8-33- 35) has not been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-102, -103, and -301 series airplanes, that requires a one-time inspection for wear and breakage of wire segments of the individual lighting units of the ceiling and sidewall lights, and replacement of any damaged wiring. This amendment also requires installation of teflon spiral wrap on the wiring of the ceiling and sidewall lights. This amendment is prompted by reports of chafing found on the electrical wiring of the cabin ceiling lighting system. The actions specified by this AD are intended to prevent the possibility of a fire on an airplane due to such chafing and consequent short circuiting, overheating, and smoking of the wires on the aircraft structure.
