What to do

Operators of affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft must update their AFMs by incorporating the specified revisions within 30 days of the directive's effective date. After updating, all flight crews must be informed of the changes and operate the aircraft accordingly. Compliance with AFM revision 42 or later approved by Transport Canada is required.

Summary

Information Systems — Incorrect Airplane Flight Manual (AFM) Wet and Contaminated Runway Stopping Distance is a Canadian Airworthiness Directive (CN CF-2022-49) addressing incorrect stopping distance data in the AFM for Bombardier BD-700-1A10 and BD-700-1A11 aircraft. The directive mandates corrections to specific performance tables related to wet and contaminated runway landing distances. It applies to certain serial numbers of these Bombardier Global 6000 and Global 5000 models.

What changed

This directive requires incorporation of a revision to the AFM to correct performance tables, specifically figures 07-35-2 and 07-35-4, which previously contained incorrect thrust reverser correction factors for contaminated runway landing distances. It supersedes earlier AFM revisions that introduced these errors and mandates use of updated AFM revisions 42 or later approved by Transport Canada.

Why it matters

Accurate stopping distance data is critical for safe aircraft operation on wet or contaminated runways. Incorrect data could lead to insufficient landing distance margins and potential runway excursions. Operators, maintenance, and compliance teams must ensure AFMs are updated to maintain regulatory compliance and flight safety.
