During takeoff, engine 2 failed at 650 meters. The captain continued, then abandoned, but the aircraft overran and struck an earth mound. All 34 occupants evacuated; some were injured.

Incident Overview

During the takeoff roll, after a distance of 650 meters, engine number 2 failed. The captain decided to continue the takeoff procedure. However, with one engine significantly diminished, power and speed were insufficient to achieve rotation. The captain subsequently abandoned the takeoff maneuver, but the aircraft was unable to stop within the remaining runway distance.

Sequence of Events

The aircraft overran the runway end and eventually collided with an earth mound. The collision destroyed the cockpit. All 34 occupants were evacuated from the aircraft, with some of them sustaining injuries.

Investigative Findings

Investigations determined that engine number 2 had lost 90% of its power during the takeoff roll. The reason for the power loss remains unknown. The official probable cause identified was wrong decisions on the part of the captain, who continued the takeoff procedure with one engine almost inoperative.
