What to do
Operators of affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft must amend their Transport Canada approved AFMs by incorporating the specified chapters and supplements within 30 days of the directive's effective date. After updating the AFM, flight crews must be informed of the changes and operate the aircraft accordingly to ensure compliance and safety.
Summary
Canadian Airworthiness Directive CF-2021-35 addresses incorrect Airplane Flight Manual (AFM) data related to wet and contaminated runway stopping distances for Bombardier Inc. model BD-700-1A10 and BD-700-1A11 aircraft, including Global Express, Global Express XRS, Global 6000, and Global 5000 variants. The directive mandates revisions to specific AFM performance charts to ensure accurate stopping distance calculations under contaminated runway conditions.
What changed
This directive requires incorporation of updated AFM chapters and supplements that correct thrust reverser correction factors and performance data for wet and contaminated runway operations. The changes affect take-off and landing performance charts, including those for operation in icing conditions and high-altitude airports. These revisions replace previously published performance data that underestimated stopping distances.
Why it matters
Accurate AFM performance data is critical for safe aircraft operation, particularly during take-off and landing on contaminated runways. Incorrect stopping distance information could lead to runway excursions, posing safety risks. Operators, maintenance, and compliance teams must ensure the AFM updates are incorporated promptly to maintain regulatory compliance and operational safety.
