EASA AD G-2021-0006
Engine Controls — Power Control — Engine Power Control Cables - Replacement
Summary
The Civil Aviation Authority Airworthiness Directive G-2021-0006 addresses the replacement of engine power control cables on BAe ATP aeroplanes. This directive applies to all manufacturer serial numbers of the BAe ATP model and focuses on engine power control-cable assemblies with specific part numbers. It mandates the installation of improved cables designed to prevent freezing caused by moisture ingress.
What Changed
This new Airworthiness Directive introduces the mandatory replacement of affected engine power control cables with a redesigned part featuring outer sleeving and rubber end gaiters to prevent moisture ingress and freezing. The improved cable has a new part number JD760J0020-030 and a life limit of 6000 flight hours. The replacement can be done one engine at a time, with separate instructions for left and right engine cables.
Why It Matters
This directive is critical for maintaining safe engine power control on BAe ATP aircraft, especially in cold conditions where cable freezing can cause stiffness or jamming of the power control lever. Failure to comply could result in partial or total loss of aircraft control, posing a significant safety risk. Operators, maintenance organizations, and compliance teams must ensure timely replacement to uphold airworthiness and regulatory compliance.
What To Do
Operators must replace the affected engine power control cables on both left and right engines with the improved part JD760J0020-030 by 30 September 2021. The replacement is considered a critical maintenance task and should be performed following the instructions in Service Bulletin ATP-76-023 Revision 02. Compliance with this directive is mandatory unless previously accomplished or alternative methods of compliance are approved by the CAA.
