What happened
During a visual approach to a runway measuring 3,975 feet in length, a turbojet aircraft experienced an extended landing roll. The pilot in command reported that the approach and descent rates appeared standard while flying over the trees. However, during the descent to the runway at idle power, the pilot observed the airspeed increasing by 16 knots above the reference speed. The pilot decided to proceed with the landing due to the aircraft's proximity to the runway and the perceived availability of extra landing distance.
As a result of the increased speed, the aircraft floated significantly past the intended touchdown point, eventually contacting the runway approximately 2,100 feet beyond the threshold. While the crew was attempting to decelerate the aircraft, it veered to the right without pilot input. The aircraft subsequently overran the departure end of the runway and struck trees. Following the impact, the pilot attempted to shut down the engines, successfully deactivating one engine despite the intense vibrations. The crew assisted all occupants in evacuating the aircraft before a post-impact fire destroyed the wreckage. There were no fatalities reported.
Findings
Investigations into the incident revealed that no mechanical or maintenance issues were present on the aircraft. Calculations based on the flight manual and environmental conditions—including a temperature of 30 degrees Celsius and zero wind—indicated that the estimated total stopping distance at reference speed was approximately 2,955 feet. The primary factor in the overrun was the unintended increase in airspeed during the final descent, which caused the aircraft to float and land much further down the runway than planned.
