Narrative:
A Cessna 208B Grand Caravan airplane sustained substantial damage in a landing accident at Yambio Airfield (HSYA), South Sudan. The Cessna operated on a UN flight from Juba to Yambio.
The flight was uneventful up to and until after touchdown, twenty metres after the threshold of runway 03, when it was noted that the aircraft steadily veered to the left. The captain, who was Pilot Monitoring, urged the Pilot Flying to counteract but the airplane continued to the left. He then took over control and applied full right rudder but this had no effect. The aircraft's left wheel entered a trench at high speed, causing the aircraft to flip over and crash 200 meters from the threshold of runway 03, coming rest in an inverted position.
All persons exited safely on their own, except two passengers who were assisted by the captain to disembark. The captain used the portable fire extinguisher to put off the fire that flickered in the engine compartment. The flying pilot sustained injuries on his right foot, while the other passengers were reported to have had minor injuries.
