What to do
Operators must inspect and adjust wiring harnesses for damage and clearance before further flight according to ACLP Service Bulletin BD500-240012 Issue 004. Compliance deadlines depend on aircraft total air time as of April 5, 2023: aircraft with 8000 hours or less must comply before 9350 total hours, and those with more than 8000 hours must comply within 1500 hours from that date. If damage is found, contact ACLP for approved repair instructions and implement them before further flight.
Summary
The Canadian Airworthiness Directive CF-2023-20R1 addresses electrical power feeder cables fouling in the wing trailing edge on Airbus Canada Limited Partnership (ACLP) Model BD-500-1A10 and BD-500-1A11 aircraft. This directive mandates inspections and adjustments of wiring harnesses to prevent damage and potential electrical arcing that could lead to fire hazards. It applies to specific serial numbers of these aircraft models.
What changed
CF-2023-20R1 revises the original AD CF-2023-20 by clarifying inspection requirements and correcting typographical errors in the associated service bulletin. It introduces a requirement to adjust wiring harnesses before further flight to prevent reintroduction of damage after repairs. The updated service bulletin BD500-240012 Issue 004 replaces the previous version for compliance.
Why it matters
This directive is critical for aviation professionals to prevent electrical arcing caused by wiring harness wear due to fouling against wing structures, which could result in fire if hydraulic leaks are present. Operators and maintenance teams must ensure compliance to maintain aircraft safety and airworthiness. Clear instructions and updated procedures reduce ambiguity and improve maintenance effectiveness.
