The aircraft was destroyed upon impact and four occupants were rescued while 19 others were killed. A day later, one of the survivor died from his injuries.

Probable cause:
The committee for the investigations of Slav air let410 aircraft registration UR-TWO has finally concluded that the cause of the accident at Yirol Eastern Lake State Republic of South Sudan was caused by a combination of the following factors:
1. Severely bad weather in the morning of the accident.( Not making a decision to return back to Juba or diverting to the nearest airportRumbek).
2. Pilot incompetency and error in setting the altimeter for Yirol airstrip before the crash. (Causing variations in altitude- flying at false altitude actually below the actual flight level).
3. Replacement of a faulty propeller in Pibor and not informing the safety department of the changes and not being given the release document for operations.
