A DHC-8-402 aircraft operated by Jazz Aviation, was conducting operating for Air Canada Express as flight 7977 from Montreal-Pierre Elliott Trudeau Airport to Toronto City Airport, Canada. While landing at Toronto City in gusty wind conditions, the aircraft bounced and touched back down firmly on runway 26. Subsequently, the FDR caution light illuminated. The aircraft then taxied to the gate as normal.
Following consultation with the operator’s maintenance via telephone, the flight crew conducted a visual inspection of the aircraft; no abnormalities were detected. It was then decided that a hard landing maintenance inspection was not required, and the aircraft was dispatched under MEL authority for the FDR caution light that remained illuminated. After the departure on the return flight to Montreal, the flight crew requested that the aircraft be inspected on arrival due to a potential hard landing. When maintenance personnel in Montreal brought the aircraft into the hangar, airframe damage to the aft right fuselage and the right main landing gear was discovered.

Weather reports about the time of the accident showed a wind from 300 degrees at 21 knots with gusts to 29-32 knots
