Abstract
This amendment adopts a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes, that requires replacement of the existing "Low Temp" terminal blocks "G" with new, fireproof ceramic terminal blocks "G" in engine zones 412, 422, 432, and 442. This action is necessary to prevent failure of the engine fire detection and suppression systems to operate properly in the event of a fire due to failure of non-fireproof terminal blocks, which could result in an undetected and uncontrollable fire in an engine. This action is intended to address the identified unsafe condition.
