What to do
Operators must update the approved flight manuals within 30 days of the directive's effective date, incorporating specified revisions. Maintenance schedules must also be revised within 30 days to include new tasks related to the anti-ice system. Additionally, the low temperature ground wing anti-ice system must be installed on affected aircraft within 60 months from February 19, 2019.
Summary
The Canadian Airworthiness Directive CF-2019-04 titled 'Cold Weather Operations — Introduction of Low Temperature Ground Wing Anti-Ice System' applies to Bombardier Inc. CL-600-2A12 (Challenger 601) and CL-600-2B16 (Challenger 601-3A/3R) aircraft with serial numbers 3001 to 3066 and 5001 to 5194. This directive mandates modifications to improve safety during cold weather ground operations by introducing a low temperature ground wing anti-ice system. It includes updates to flight manuals, maintenance schedules, and installation of the new anti-ice system.
What changed
CF-2019-04 introduces a mandatory modification that enables activation of the wing anti-ice system at low temperatures during ground operations when the engine air intake anti-ice system is activated. It requires updates to the approved flight manuals and maintenance task schedules, and mandates installation of the low temperature ground wing anti-ice system within 60 months of the directive's effective date.
Why it matters
This directive addresses the critical safety risk of wing contamination by snow, slush, or ice during extended ground operations in cold weather, which can severely degrade aircraft controllability at takeoff. Compliance ensures operators reduce the risk of premature stall and loss of control, enhancing flight safety for the Bombardier Challenger 601 fleet. Maintenance and compliance teams must integrate these changes to meet regulatory requirements and maintain airworthiness.
