Suosituksen perustelu
In a horizontal stabilizer trim fault situation, prior to autopilot disengagement, it is justified to consider adjusting the airspeed to suit the horizontal stabilizer angle. Likewise, the Fasten Seat Belts sign shall be turned on. Both measures can mitigate the risk of serious injury. A airspeed also reduces the stress to the aircraft following autopilot disengagement.
Recommendation
Safety Investigation Authority, Finland recommends that Transport Canada review the content of Bombardier CL300-type aircraft QRH checklists as regards horizontal stabilizer trim system faults.
