What to do
Operators must replace the ELT antenna and inspect the fuselage skin within specified compliance times based on the ELT antenna's accumulated air time, ranging from 200 to 850 hours after the effective date or before certain total hours are reached. After the initial replacement, these actions must be repeated every 2500 hours of air time. Repairs must be made if any damage is found during inspections.
Summary
Canadian Airworthiness Directive CF-2021-10 addresses vibration-induced failures on Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft equipped with Gogo 2Ku antenna radomes part numbers P23743-605 or P23743-606. The directive mandates replacement of the Emergency Locator Transmitter (ELT) antenna and inspection of the fuselage skin around the antenna attachment area to prevent antenna loss and fuselage damage. This AD applies to aircraft from serial number 50001 and 55001 onward respectively.
What changed
This new Airworthiness Directive introduces mandatory replacement of the ELT antenna and repetitive inspections of the fuselage skin around the antenna attachment area to mitigate vibration damage caused by the Gogo 2Ku antenna radome. It establishes specific compliance times based on accumulated air time on the ELT antenna and requires ongoing repetitive maintenance every 2500 hours of air time.
Why it matters
This directive is critical for aviation professionals to prevent potential loss of the ELT antenna and fuselage cracks that could compromise cabin pressure integrity. Operators and maintenance teams must ensure timely compliance to maintain aircraft airworthiness and safety. Failure to comply could lead to structural damage and regulatory violations affecting operational approval.
