What happened
On a flight traveling from Williams Lake, British Columbia, to Hinton, Alberta, a Mitsubishi MU-300 Diamond was operating under instrument flight rules. The flight crew, consisting of two pilots, was informed by the Edmonton Area Control Centre regarding weather conditions at the Jasper townsite prior to being cleared to descend from flight level 270. Following this information, the crew transitioned to visual flight rules for an approach and landing on runway 02 at Jasper-Hinton Airport.
During the final stages of the approach, the aircraft encountered moderate turbulence. To manage airspeed fluctuations caused by the unstable air, the captain increased the reference airspeed from 105 to 115 knots. The crew observed that the wind sock for runway 02 was fully extended and experiencing frequent direction changes.
As the aircraft approached the runway, power was reduced to idle at an altitude of 50 feet. The Mitsubishi MU-300 Diamond made contact with the runway approximately 1,000 feet from the threshold. During the subsequent landing roll, the captain applied maximum braking. Realizing the aircraft would not stop within the remaining runway length, the pilot attempted a commanded swerve to assist in deceleration. This maneuver caused the aircraft to skid, eventually coming to rest 255 feet beyond the end of the runway. While the aircraft suffered substantial damage, there were zero fatalities and zero injuries among the four occupants.
Findings
During the landing roll, the pilot's attempt to stop the aircraft involved applying maximum braking followed by a swerving maneuver to mitigate the overrun.
