EASA AD CF-2020-49R1
Flight Controls — Inboard-Flap Susceptibility to Corrosion
Canadian Airworthiness Directive CF-2020-49R1 addresses corrosion susceptibility in the inboard flaps of Bombardier Inc. model BD-700-1A10 and BD-700-1A11 aircraft. This directive mandates enhanced inspection procedures to detect internal corrosion that could weaken flap structure and potentially lead to flap detachment. The directive applies to specific serial numbers of these aircraft models and aims to improve safety through revised maintenance schedules.
