EASA AD CF-2020-23
Ice and Rain Protection — Wing Anti-Ice System — Piccolo Duct Holes Not Conforming to Drawing Requirements
Canadian Airworthiness Directive CF-2020-23 addresses non-conforming piccolo duct holes in the wing anti-ice system of MHI RJ Aviation ULC aircraft models CL-600-2C10, CL-600-2C11, and CL-600-2D24. The directive identifies specific serial numbers affected by manufacturing deviations in piccolo duct bleed holes that could impair wing anti-ice protection. This AD mandates inspection and replacement of affected piccolo duct assemblies to ensure continued airworthiness.
