Circumstances:
The aircraft was carrying three passengers, a crew of four and 209 kilos of mail. Two takeoff attempts were rejected because the aircraft was too heavy. In such conditions, the captain decided to start the takeoff roll from a further point at the airport. On the third attempt, after a course of 1,500 metres, the aircraft impacted a dirt bank. The undercarriage were torn off and the airplane crashed. The radio operator was seriously injured and all six other occupants were killed.

Probable cause:
The total weight of the aircraft was too high at the time of the accident, this explain why the airplane was unable to leave the ground. Additionally, it appears that a cockpit panel was improperly secured during the takeoff roll that was completed in heavy rain falls, which was considered as a contributory factor.
