Accident
During takeoff from runway 26 at Espinal Airfield, the aircraft deviated left and failed to become airborne. It overran the 1,010-meter gravel strip, crossed a road, and came to rest 275 meters beyond the runway, where it burst into flames. All four crew members evacuated without injury, but the aircraft was destroyed by fire.
Aircraft Background
The aircraft had been stolen in December 1992 and was later found abandoned at Espinal Airfield. SEC Colombia subsequently purchased it and completed an in-site C1 check before transferring it to Bogotá-El Dorado Airport.
Investigation
Investigation determined that gravel runway 26 at Espinal Airfield was certified only for agricultural aircraft with a maximum takeoff weight of 4,400 pounds. The Convair involved in the accident had a takeoff weight of 38,888 pounds, far exceeding the runway's certification limits.
Probable Cause
The official probable cause was the crew's decision to take off from a runway unfit for the flight, resulting in a lack of performance on the soft surface that prevented the aircraft from reaching VMCA, V1, VR, and V2 speeds. A contributing factor was the authorization by SEC Colombia to conduct the takeoff from that runway.
