AD/CL-600/14 Engine Pylon Fuel Feed Tube Assembly Modification Cancelled (Cth)

AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/CL-600/14.

Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes

AD/CL-600/14 Engine Pylon Fuel Feed
Tube Assembly - Modification 11/2009

Requirement:

CANCELLED.

This AD is cancelled on 22 October 2009.

Background:

This unique Australian AD raised in 1983 against Canadair Challenger Alert Service Bulletin (SB) No. A600-0352 required a modification to provide the required locking feature for bolts securing the engine fuel feed tube assembly to the fuel shut-off valve in each engine pylon.

Compliance was:  Prior to the issue of an Australian Certificate of Airworthiness.

This AD has been sufficiently promulgated over an extended period for the affected aircraft to have been modified by now; therefore this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
