## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace Model BAe 146-100A, -200A, and -300A, and Model Avro 146-RJ series airplanes, that requires repetitive inspections of the attachment brackets between the horizontal and vertical stabilizers to detect intergranular corrosion, and follow-on actions. 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 detect and correct reduced structural integrity of the stabilizer brackets due to corrosion, which could result in reduced controllability of the airplane.
