What happened
Upon landing on runway 7, the aircraft failed to stop within the available runway length and overran the pavement. During the descent, the crew had to descend rapidly due to high minimum en route altitudes in the surrounding airspace. This resulted in an approach that was not stabilized, characterized by high energy levels. The aircraft crossed the runway threshold and touched down at a speed approximately 17 knots above the prescribed target speed.
While the aircraft reached the designated touchdown area, the combination of the high approach speed and an 8-knot tailwind component contributed to the overrun. Evidence from the scene and witness accounts indicated that the aircraft was traveling significantly faster than Vref during the final stages of the landing.
Findings
Investigation into the mechanical systems revealed that the lift dump panels failed to extend following the touchdown. However, investigators could not identify a specific mechanical reason for this failure, as no malfunctions were detected in the braking or lift dump systems.
Ultimately, the primary factor in the accident was the pilot's execution of an unstabilized approach at excessive speeds. The high airspeed, compounded by the tailwind, exceeded the safe parameters for the landing. The investigation concluded that the flight conditions and the high speed of the aircraft should have prompted the pilot to execute a missed approach rather than attempting to land.
