What to do
Operators of the specified Airbus Canada BD-500-1A11 aircraft must inspect the radome diverter strips within eight months of the effective date. If painted strips are detected, the radome must be removed and replaced following the prescribed Aircraft Maintenance Publication procedures. No further action is required if the diverter strips are unpainted.
Summary
Canadian Airworthiness Directive CF-2022-04 addresses the issue of painted radome lightning diverter strips on Airbus Canada Limited Partnership model BD-500-1A11 aircraft, specifically serial numbers 55070, 55075, 55080, 55084, 55085, 55096, and 55099. The directive mandates inspection and potential replacement of the radome to ensure lightning protection effectiveness. This directive aims to maintain the safety and airworthiness of affected aircraft by preventing lightning damage to critical avionics.
What changed
CF-2022-04 introduces a new requirement to inspect the radome diverter strips for paint and replace the radome if painted strips are found. It establishes compliance procedures referencing specific Aircraft Maintenance Publication data modules for removal and installation of the radome. This directive is a new regulation addressing a production issue with painted diverter strips compromising lightning protection.
Why it matters
This directive is crucial for aviation professionals as painted diverter strips can reduce lightning protection, risking damage to the nose radome and associated antennas such as the localizer and glideslope. Operators and maintenance teams must ensure compliance to prevent potential loss of instrument landing system signals and maintain aircraft safety. Timely adherence helps avoid costly repairs and operational disruptions caused by lightning damage.
