EASA AD CF-2018-32R1
SUPERSEDED BY TCCA AD CF-2022-37
Summary
Canadian Airworthiness Directive CF-2018-32R1 is an amendment affecting MHI RJ Aviation ULC model CL-600 series aircraft, including CL-600-2B19, CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25. It addresses issues with the autopilot altitude capture modes during engine failure conditions that may cause airspeed to drop below safe limits. The directive mandates updates to the Airplane Flight Manual (AFM) to include specific limitations and abnormal procedures related to velocity decay during low-level altitude capture in one engine inoperative scenarios.
What Changed
This revision, CF-2018-32R1, updates the previous AD CF-2018-32 by adding references to the (V) ALTV CAP mode in the AFM limitations and abnormal procedures, correcting omissions in the original mandated changes. It ensures that warnings now cover ALTS CAP, (V) ALTS CAP, and (V) ALTV CAP modes where applicable. The CL-600-2B19 model is excluded from the (V) ALTV CAP mode as it does not have this feature.
Why It Matters
This directive is critical for flight safety as it addresses a condition where autopilot altitude capture modes may not properly compensate for engine failure, potentially leading to unsafe airspeed decay. Operators and maintenance teams must ensure AFM updates are incorporated to provide flight crews with the necessary procedures to maintain safe operating speeds. Compliance helps prevent incidents related to autopilot guidance during critical climb phases with one engine inoperative.
What To Do
Affected operators must amend their Transport Canada approved AFMs within 60 days of the effective date by incorporating the specified warnings and abnormal procedures for engine failure during altitude capture modes. Operators with previously amended AFMs meeting certain revision levels are considered compliant. Additionally, all flight crews must be informed of these AFM changes to ensure proper procedural adherence.
