EASA AD CF-2021-06
Ice and Rain Protection — Wing Anti-Ice System — Wing Stall Prior to Touchdown due to Wing Leading Edge Icing
Canadian Airworthiness Directive CF-2021-06 addresses the risk of wing stall prior to touchdown caused by wing leading edge icing on Bombardier Challenger 600 series aircraft, including models CL-600-1A11, CL-600-2A12, and CL-600-2B16. This directive mandates revisions to the Aircraft Flight Manual (AFM) to include new limitations and procedures for the Wing Anti-Ice (WAI) system to prevent ice accumulation on wing leading edges. The directive applies to specific serial numbers within these models.
