Jazz operated damaged aircraft after 2017 hard landing

The hard landing of a Jazz Aviation Bombardier Q400 in 2017 substantially damaged the aircraft and generated enough load to trigger a switch designed to activate only after a crash, according to a report from the Transportation Safety Board of Canada. The report notes that the company was unaware of the damage and operated the aircraft prior to making repairs. The incident involved Jazz flight 7977, a Q400 from Montreal to Billy Bishop Toronto City airport on the evening of 9 November last year. Immediately prior to touchdown on Billy Bishop's Runway 26, wind shear caused the aircraft's speed to decline, leading the pilot flying to increase power to the Q400's Pratt & Whitney Canada PW150A turboprops, says the TSB's report released on 9 July. The aircraft then touched down on the runway and a pilot reduced the throttle, but the aircraft lifted again when more wind shear caused the airspeed to increase, the TSB says.
