What to do
Operators must amend the AFM with specified Temporary Revisions within 30 days of the original and revised effective dates, implement the prescribed operational procedures immediately, and provide crew training on flap failure procedures and zero flap landings within specified timeframes. Maintenance actions per Bombardier Service Bulletin 601R-27-150 must be completed according to the defined schedule, including tasks before November 30, 2007, and within 24 months or 4000 flight hours after July 31, 2007.
Summary
Canadian Airworthiness Directive CF-2007-10R2 addresses flight control flap failures on MHI RJ Aviation ULC model CL-600-2B19 aircraft, serial numbers 7003 through 7990 and 8000 onwards. The directive mandates changes to the Airplane Flight Manual, operational procedures, training, and maintenance actions to mitigate risks associated with flap malfunctions, which can lead to increased landing distances and fuel consumption during diversions.
What changed
This revision CF-2007-10R2 removes previous reporting requirements as mitigating actions have been implemented and future events will be monitored through Service Difficulty Reports. It continues to enforce AFM updates, operational restrictions, crew training on zero flap landings, and maintenance tasks including cleaning, lubrication, pressure testing, and low temperature torque testing of flap actuators and flexible drive shafts.
Why it matters
The directive is critical for operators and maintenance organizations to reduce the risk of flap failures that can compromise flight safety and operational efficiency. Compliance ensures crews are prepared for abnormal flap conditions, helps maintain flap system reliability, and prevents fuel exhaustion scenarios during diversions. It also aligns maintenance practices with regulatory standards to maintain airworthiness.
