What to do
Operators and maintenance personnel must incorporate the Safe Life Limitation Task 30-11-10-701 into their Maintenance Requirements Manual within 60 days from the effective date of 20 April 2020. Initial compliance must follow the phase-in schedule outlined in Temporary Revision ALI-0721. Using superseding Temporary Revisions or later approved MRM revisions also satisfies the directive requirements.
Summary
The Airworthiness Directive CF-2020-08 is issued by Transport Canada and addresses the Wing Anti-Ice (WAI) system on Bombardier Inc. model CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aircraft. It introduces a safe life limit for the pneumatic telescopic duct used in the WAI system to prevent failures that could affect aircraft safety. This directive mandates maintenance updates to ensure continued airworthiness of the affected aircraft.
What changed
This new Airworthiness Directive introduces a life limitation on the pneumatic telescopic duct of the Wing Anti-Ice system. It requires incorporation of a new Safe Life Limitation Task 30-11-10-701 into the Maintenance Requirements Manual, with a phase-in compliance schedule as specified in Temporary Revision ALI-0721 dated 20 December 2019. The directive aims to prevent duct failures that have caused slat jams and structural damage.
Why it matters
The directive is critical for operators and maintenance organizations to prevent potential loss of wing anti-ice functionality, slat skew, and structural damage due to duct failure. Compliance ensures continued safe operation of the affected Bombardier CL-600 series aircraft and avoids in-flight alerts and possible safety hazards. It also aligns maintenance practices with updated airworthiness limitations mandated by Transport Canada.
