EASA AD CF-2023-67
Electrical Cabin Systems — Lug — Improper Terminal Lug Selection
Summary
Canadian Airworthiness Directive CF-2023-67 addresses improper terminal lug selection in electrical cabin systems on Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. The directive applies to specific serial numbers of these models and focuses on correcting terminal lug installations at lavatory and galley locations. This action aims to prevent electrical issues that could lead to false alarms and system malfunctions.
What Changed
CF-2023-67 introduces a new requirement to inspect and replace incorrect terminal lugs installed in the lavatory and galley areas of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft. The directive mandates compliance within 9350 flight hours from the effective date and references a specific service bulletin for the corrective procedure.
Why It Matters
This directive is critical for maintaining the reliability of cabin electrical systems, preventing false alarms from smoke detectors and oxygen pressure sensors, and ensuring proper operation of cabin temperature control and lavatory flush systems. Compliance reduces crew workload and enhances flight safety by avoiding unnecessary diversions or altitude changes caused by system malfunctions.
What To Do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must modify the terminal lugs in the lavatory and galley areas according to Airbus Canada Service Bulletin BD500-254014, Issue 001, or later approved revisions. This must be completed within 9350 flight hours from the effective date of 2023-10-18 unless already done.
