Applicability
| Type | Manufacturer | Model | Details |
|---|---|---|---|
| aircraft | Bombardier | CL-600-2B19 | Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes |
| aircraft | Aviat | Various | Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes |
Unsafe Condition
The Bombardier CL-600-2B19 airplanes have had a history of flap failures at various positions, which may result in a significant increase in required landing distances and higher fuel consumption than planned during a diversion.

Required Actions
Revise the airplane flight manual (AFM) to incorporate a temporary revision (TR) into the AFM, adding operational procedures into the AFM, train flight crewmembers and operational control/dispatch personnel on the operational procedures, and perform corrective maintenance actions including a pressure test of the flexible drive-shaft and corrective actions, and a low temperature torque test of the flap actuators and corrective actions. Additionally, require repetitive low temperature torque tests of the flap actuators and corrective actions, revise the AFM to incorporate a new TR (adding maximum flaps operating speed data and clarifying maximum flaps extended speeds), and modify the Operational Limitations. Also, revise the annual simulator training for 'Flap Zero Landing' events and revise the previously required training for flight crewmembers and operational control/dispatch personnel on the operational procedures.

Compliance Time
Within 10 flight cycles following the initial on-ground circuit breaker reset operation, or before further flight if another flap fail event occurs after the initial circuit breaker reset operation.
