Occurrence Details
On February 23, 2020, a Bombardier CL-600-2B16 (Challenger 605), registration C-GKCP, operated by the Canadian Pacific Railway Company, departed from Palm Beach International Airport, Florida, en route to Calgary International Airport, Alberta. The aircraft carried 3 crew members and 10 passengers.
Flight Sequence
During the descent into the Calgary area, the flight crew selected flaps 20. Immediately, a "FLAPS FAIL" caution message appeared on the engine indication and crew alerting system (EICAS). The crew requested delaying vectors to the east and performed the flaps fail procedure from the Quick Reference Handbook (QRH). Subsequently, the aircraft was sequenced for a zero-flap landing on Runway 17R.
Landing and Damage
The aircraft touched down at 1434 Mountain Standard Time. During the landing roll, maximum reverse thrust was selected. The aircraft's pitch attitude increased to the point where it became partially airborne for a brief moment, and the rear fuselage struck the runway. As the crew recovered from the nose-high attitude, the nose landing gear struck the runway hard. The aircraft then completed the landing roll and taxied to the intended parking area.
No injuries were reported among the occupants. However, significant damage was noted to the forward fuselage.
Safety Communication
On July 29, 2020, the Transportation Safety Board of Canada issued Air Safety Information Letter A20W0016-D1-L1, addressing the Challenger 605 series flap system inspection interval and a cross-fleet product improvement for the Challenger CL60 series.
