What to do
Operators must replace the ELT antenna and inspect the fuselage skin within specified compliance times based on ELT antenna usage hours, with repeat replacements and inspections every 2500 hours air time. Within 2000 hours air time from the directive's effective date, the aluminum ELT antenna must be installed as a terminating action. Any damage found during inspections must be repaired before further flight to comply with the directive.
Summary
Canadian Airworthiness Directive CF-2022-67 addresses vibration issues on the fuselage and Emergency Locator Transmitter (ELT) antenna for Airbus Canada Limited Partnership aeroplanes Model BD-500-1A10 and BD-500-1A11 equipped with Gogo 2Ku antenna radomes P/N P23743-605 or P/N P23743-606. This directive mandates replacement and inspection of the ELT antenna to prevent failures caused by vibration loads from air vortices. It applies to specific serial numbers of these aircraft models and aims to maintain aircraft safety and structural integrity.
What changed
CF-2022-67 supersedes AD CF-2021-10 by mandating the installation of a new aluminum ELT antenna designed to prevent vibration-induced failures. It maintains previous inspection and replacement requirements until the aluminum antenna is installed and limits applicability to aircraft without the aluminum antenna installed in production. The directive also updates compliance times and inspection intervals based on accumulated air time on the ELT antenna.
Why it matters
This directive is critical for operators and maintenance teams to prevent ELT antenna failures that could lead to antenna loss and fuselage cracks, potentially compromising cabin pressure. Compliance ensures continued airworthiness and safety of affected aircraft, reducing risk of in-flight structural damage and emergency locator transmitter malfunction. It also provides a terminating action to repetitive inspections, improving maintenance efficiency once the aluminum antenna is installed.
