EASA AD CF-2023-02
Landing Gear — Nose Landing Gear — Steering Shutoff Valve Slow to Deactivate
Canadian Airworthiness Directive CF-2023-02 addresses an issue with the nose landing gear steering shutoff valve on Bombardier Inc. model BD-700-1A10 and BD-700-1A11 aeroplanes, serial numbers 9002 through 9998 and 60001 through 60068. The directive mandates replacing the existing steering selector valve part number 23600-101 with a redesigned valve part number 23600-103 to improve response time. This AD aims to prevent runway excursions caused by slow deactivation of the steering valve under low temperature conditions.
