What to do
Operators must inspect the electrical harnesses in overhead storage compartments within 4400 flight hours or 24 months from August 7, 2023, for applicable aircraft groups. Final corrective modifications must be completed within 8800 flight hours or 48 months from the same date. Aircraft in certain groups require no immediate action. Compliance with the specified service bulletin revisions is mandatory to terminate the directive's requirements.
Summary
The Canadian Airworthiness Directive CF-2023-79 addresses the improvement of overhead bin harnesses above class dividers on Mitsubishi Heavy Industries RJ Aviation ULC aircraft, specifically Bombardier CRJ models CL-600-2C10, CL-600-2D15, and CL-600-2D24 with specified serial numbers. It mandates inspections and modifications to prevent electrical harness damage in overhead storage compartments that could affect critical passenger systems. This directive updates and revises the applicability of the previous directive CF-2023-56.
What changed
CF-2023-79 revises the applicability of the previous directive CF-2023-56 by adding new affected aircraft serial numbers and removing some previously included ones. It maintains the inspection and modification requirements to prevent damage to electrical harnesses in overhead bins above class dividers. The directive also clarifies grouping of aircraft for tailored corrective actions.
Why it matters
This directive is crucial for operators and maintenance organizations to ensure the integrity of electrical harnesses in overhead storage compartments, preventing potential failures in passenger safety and comfort systems such as emergency lighting, oxygen supply, and air conditioning. Compliance reduces the risk of in-flight system malfunctions and enhances overall aircraft safety. It also provides clear guidance for maintenance planning and regulatory compliance.
