On 23 February 2020, a Bombardier Challenger 605 making a flapless landing after a system failure during descent briefly lost control when reverse thrust selection after a normal touchdown was followed by the aircraft becoming airborne before stick push activation was followed by a hard second touchdown. Structural and abrasion fuselage damage was caused. The Investigation attributed the flap failure to corrosion within the specified maintenance inspection interval and the brief loss of control during landing to a combination of inadequate crew preparation for the landing and the fact that simulator replication of aircraft handling did not correspond to reality.
