EASA AD CF-2023-27
Electrical System Installation — Rear Cabin — Low Clearance Condition
Summary
The Airworthiness Directive CF-2023-27 titled 'Electrical System Installation — Rear Cabin — Low Clearance Condition' applies to Airbus Canada Limited Partnership aeroplanes BD-500-1A10 and BD-500-1A11 with specified serial numbers. It addresses a potential chafing issue between a power harness and the left side window shade in the rear cabin area. This directive mandates corrective action to prevent electrical system failures that could affect emergency equipment functionality.
What Changed
This new Airworthiness Directive introduces a requirement to reroute the power harness in the rear cabin to prevent chafing and potential damage. The modification involves altering an insulation blanket and installing a standoff and clamp on the left side stringer between frames 65 and 67. Compliance must be achieved within 9350 flight hours from the effective date.
Why It Matters
This directive is critical for aviation professionals because damage to the power harness can lead to emergency equipment failures, including partial loss of the public address system and failure to deploy passenger oxygen masks. Operators and maintenance teams must ensure compliance to maintain aircraft safety and regulatory conformity. Failure to comply could compromise passenger safety and regulatory approval for flight operations.
What To Do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must reroute the power harness following Airbus Canada Service Bulletin BD500-352004, Issue 001, or later approved revisions. The required modifications include adjusting the insulation blanket and installing hardware to prevent harness damage. All actions must be completed within 9350 flight hours from May 18, 2023.
