Narrative:
Summit Air flight SUT8152, an Avro RJ100, landed on runway 10 at Yellowknife Airport, NT (YZF), touching down approximately 1600 feet beyond the threshold. The runway had puddles of standing water from medium to heavy rains that had fallen recently before the aircraft landed. During rollout, the aircraft experienced decreased braking action due to hydroplaning while going through a large puddle. The pilot flying applied maximum braking for the duration of the landing roll, per the recommended procedure for hydroplaning and the anti-skid system worked normally. While decelerating, the aircraft exited the end of the runway, stopping approximately 20 feet beyond the paved edge of the runway on a gravel surface. The aircraft taxied under its own power to return to the gate. The aircraft received no damage. There were no injuries or property damage.
