## Summary

We propose to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This proposed 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 proposed AD would require repetitive inspections and, depending on findings, repair of the pylon pick-up brackets. We are proposing 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.
