## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-100, -200, and -300 series airplanes, that requires a one-time inspection to detect discrepancies in the electrical wiring and wiring harness behind the lavatory, and corrective actions. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent chafing of electrical wiring, which could result in severe overheating of the wiring, consequent smoke in the flight deck and cabin, and possible injury to flightcrew or passengers.
