What to do
Operators of Bombardier BD-100-1A10 aircraft must revise the applicable AFM non-normal procedures as specified in CF-2021-14 within 60 days of the effective date. Flight crews must be informed of these changes and trained to follow the updated spoiler fault procedures each time the EICAS messages appear. Additionally, operators may consider implementing Bombardier's software upgrades to reduce the occurrence of these messages.
Summary
Canadian Airworthiness Directive CF-2021-14 addresses intermittent and repetitive Engine Indication and Crew Alerting System (EICAS) messages related to the Spoiler Electronic Control Unit (SECU) on Bombardier BD-100-1A10 aircraft. The directive applies to all serial numbers of this model and requires updates to the Airplane Flight Manual (AFM) to include specific cautions and notes for spoiler fault procedures. This AD aims to ensure flight crews properly respond to these messages to maintain safe flight operations.
What changed
CF-2021-14 introduces a mandatory revision to the AFM for Bombardier BD-100-1A10 aircraft to add a caution and note in the spoiler fault non-normal procedures. It highlights that the intermittent and repetitive EICAS messages are valid and must be acted upon each time they appear. The directive also references available software upgrades from Bombardier that can eliminate these messages for certain SECU configurations.
Why it matters
This directive is important because the repetitive nature of the spoiler fault messages can increase pilot workload and risk desensitization, potentially leading to incomplete or missed checklist actions. Ensuring crews follow the updated procedures reduces the risk of improper responses to genuine system alerts, thereby enhancing flight safety. Operators and maintenance teams must be aware of these changes to maintain regulatory compliance and operational readiness.
