Summary
Canadian Airworthiness Directive CF-2019-29 addresses a flight control issue involving the multi-function spoiler (MFS) jam on Bombardier Inc. model BD-100-1A10 aircraft, serial numbers 20003 through 20788. The directive mandates updates to the Airplane Flight Manual procedures to manage uncommanded spoiler deployment that can cause high crew workload during roll control. This AD aims to enhance flight safety by providing revised non-normal procedures for affected aircraft.
What changed
CF-2019-29 introduces a requirement to amend the approved Airplane Flight Manual by incorporating updated non-normal procedures related to flight controls and the multi-function spoiler jam scenario. It also requires operators to inform all flight crews of these procedural changes. This is a new regulation addressing a specific in-flight spoiler failure event.
Why it matters
This directive is critical for operators and maintenance teams because it directly impacts flight safety by reducing the risk of loss of roll control due to uncommanded spoiler deployment. Compliance ensures crews have updated procedures to manage this failure mode effectively, lowering pilot workload and enhancing operational safety. It also affects compliance teams who must ensure adherence to Canadian Aviation Regulations regarding airworthiness directives.
