An aircraft attempting takeoff from a dirt runway with puddles struck cones, went off runway, then hit trees and crashed in flames, killing 39 and injuring one.

Runway Conditions and Takeoff Attempt

The accident occurred during a takeoff attempt from a dirt runway that had standing puddles of water. The pilot-in-command initiated rotation after a ground roll of 345 meters, at which point the nose gear lifted off. However, the aircraft continued along the runway for another 150 meters before the right main gear struck two cones positioned on the right side of the runway.

Departure from Runway and Initial Climb

Following the cone strike, the airplane departed the runway surface and eventually became airborne after a total ground roll of 945 meters. During the initial climb, after traveling approximately 200 meters and reaching an altitude of 14 meters, the aircraft impacted trees, stalled, and subsequently crashed in a wooded area. The impact was followed by a fire that destroyed the aircraft.

Casualties and Damage

One passenger sustained injuries, while 39 other occupants were killed. The aircraft was consumed by a post-crash fire.

Probable Cause

The official investigation determined that the crew attempted to take off from an impassable runway with a tailwind component, which contributed to the accident.
