## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace Model BAe 146 and Avro 146-RJ series airplanes, that requires 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 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 damage to the fuel feed pipe, which could result in fuel leaks and an increased potential for fire on the airplane.
