Airworthiness Directive · Amendment 39-9009 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited BAe 146-100A, BAe 146-200A, BAe 146-300A.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes an existing airworthiness directive (AD), applicable to British Aerospace Model BAe 146-100A, -200A, and -300A series airplanes, that currently requires replacing the quick release coupling halves on each end of the pump case drain line on the hydraulic engine driven pump (EDP) on the number 2 and number 3 engines with improved fire resistant coupling halves. This amendment revises the applicability of the existing AD. This amendment is prompted by the identification of additional airplanes that are subject to the addressed unsafe condition. The actions specified by this AD are intended to prevent hydraulic fluid leakage from the pump case drain line quick release coupling, which could fuel the flames in the event of an engine fire.
