Airworthiness Directives; de Havilland Model DHC-8-102, -103, - 106, -201, -202, -301, -311, and -315 Series Airplanes

概要

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain de Havilland Model DHC-8- 102, -103, -106, -201, -202, -301, -311, and -315 series airplanes. This proposal would require a one-time inspection to detect chafing of electrical wires in the cable trough below the cabin floor; repair, if necessary; installation of additional tie-mounts and tie-wraps; and application of sealant to rivet heads. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent chafing of electrical wires, which could result in an uncommanded shutdown of an engine during flight.
