Following an uneventful flight from Juba, the crew started the approach to Wau but encountered poor weather conditions and low visibility. During the last segment, while trying to land, it appears the aircraft was misaligned and hit a truck from the fire brigade. Out of control, it crashed near the runway threshold and came to rest in flames. All 45 occupants were able to evacuate the aircraft that was destroyed by a post crash fire. 18 passengers were injured and transferred to hospital.
