What to do
Operators of Bombardier BD-100-1A10 aircraft must update their Airplane Flight Manuals within 30 days of the directive's effective date by incorporating the specified emergency and normal procedures. After updating the manuals, all flight crews must be briefed on the new procedures for handling unreliable airspeed. Compliance must be completed by 2019-08-18.
Summary
Canadian Airworthiness Directive CF-2019-24 addresses unreliable air data in the cockpit for Bombardier Inc. BD-100-1A10 aeroplanes, serial numbers 20001 through 20688. This directive mandates updates to the Airplane Flight Manual to include procedures for handling unreliable airspeed and go-around scenarios. The directive aims to enhance flight safety by providing crews with guidance to manage air data system failures caused by high altitude icing.
What changed
CF-2019-24 introduces a requirement to amend the Transport Canada approved Airplane Flight Manual by incorporating specific emergency and normal procedures related to unreliable airspeed and go-around after takeoff. It also requires operators to inform flight crews about these procedural changes. This is a new regulation targeting the BD-100-1A10 aircraft to mitigate risks associated with air data system failures.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk linked to loss of air data system information due to high altitude icing. Operators and maintenance teams must ensure compliance to prevent incidents that could compromise safe flight and landing. Compliance ensures crews are prepared to stabilize aircraft attitude and airspeed during unreliable air data events, improving overall flight safety.
