What to do
Operators of affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft must amend their AFMs within 30 days of the effective date by incorporating the specified chapters and supplements approved by Transport Canada. Flight crews must be informed of these changes and operate the aircraft accordingly. Compliance with this directive is mandatory to meet Canadian Aviation Regulations.
Summary
Airworthiness Directive CF-2024-27 is issued by Transport Canada and addresses incorrect approach speed adders and landing distance factors in the Airplane Flight Manual (AFM) for Bombardier Inc. BD-700-1A10 and BD-700-1A11 aircraft models. This directive applies to specific serial numbers of these models and corrects errors related to the SLAT-FLAP FAIL caution Crew Alerting System message and jammed or inoperative Slat/Flap Control Lever procedures. The directive mandates updates to the AFM to ensure accurate performance data is used during approach and landing.
What changed
CF-2024-27 revises the applicability of the previous AD CF-2024-06 to include additional aircraft serial numbers and maintains the requirement to amend the AFM with corrected approach speed adders and landing distance factors. It requires incorporation of updated non-normal procedures related to slat and flap control system failures. The directive ensures that all affected aircraft operate with the correct performance data as approved by Transport Canada.
Why it matters
This directive is critical for aviation professionals because incorrect AFM data can lead to unsafe flight operations, particularly during approach and landing phases when slat or flap control issues occur. Operators and maintenance teams must ensure compliance to avoid performance shortfalls that could compromise safety. Accurate AFM data supports proper flight crew decision-making and regulatory compliance.
