Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain British Aerospace Model BAe 146 and BAe Avro 146-RJ series airplanes. This proposal would require repetitive inspections to detect signs of chafing to the fuel feed pipe, and repair or replacement of the fuel feed pipe with a serviceable part, if necessary; and ensuring that responder units, electrical connector backshells, and associated wiring are undamaged and are positioned correctly to provide maximum clearance with the fuel pipe. 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 damage to the fuel feed pipe, which could result in fuel leaks and an increased potential for fire on the airplane.
