## Abstract

We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This AD was prompted by a report of a cracked pick-up bracket of the forward outboard pylon of the number 1 engine due to stress corrosion. This AD requires repetitive inspections and, depending on findings, repair of the pylon pick-up brackets. We are issuing this AD to detect and correct cracking of the pick-up bracket, which could result in the engine pylon separating from the wing, with consequent damage to the airplane and reduced controllability.
