## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited Model BAe 146 series airplanes, that requires repetitive inspections to detect cracking of the horizontal butt joint of the rear pressure bulkhead and repair, as necessary. This amendment also requires installation of new joint plates on the aft face of the rear pressure bulkhead, which terminates the requirements of this AD. This action is necessary to prevent cracking of the horizontal butt joint of the rear pressure bulkhead, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
