What to do
Operators must clean and grease all slat tracks before accumulating 2550 total hours air time or within 850 hours air time from the effective date if below that threshold, or inspect, clean, grease, and repair if above 2550 hours, following the specified service bulletins. Repeat inspections and maintenance must occur every 2550 hours air time thereafter. Additionally, within 30 days of inspection, operators must submit required data forms to Airbus Canada Limited Partnership as instructed.
Summary
Canadian Airworthiness Directive CF-2021-43 addresses corrosion and wear issues on the slat tracks of Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. The directive mandates inspections, cleaning, greasing, and repairs of slat tracks to prevent potential structural damage caused by slat panel detachment. This AD applies to aircraft with serial numbers 50001 and subsequent for the BD-500-1A10, and 55001 and subsequent for the BD-500-1A11.
What changed
This new Airworthiness Directive introduces mandatory repeat inspections and maintenance actions on the slat tracks of affected Airbus Canada Limited Partnership aircraft due to reported corrosion and wear. It requires operators to follow specific service bulletins for cleaning, greasing, inspecting, and repairing slat tracks, including data collection to support further investigation and corrective measures.
Why it matters
This directive is critical for aviation professionals to ensure the structural integrity of aircraft wings by preventing slat panel loss caused by corrosion and wear. Compliance helps avoid catastrophic damage and enhances flight safety. Maintenance and compliance teams must integrate these inspections and repairs into their scheduled maintenance to meet regulatory requirements and maintain airworthiness.
