What happened
During the final approach phase to El Obeid Airport, the flight crew encountered an unexpected issue that necessitated the shutdown of the left engine. To mitigate the impact on flight performance, the propeller was feathered. Following the landing, the aircraft failed to decelerate sufficiently within the available runway length.
The momentum of the plane caused it to overrun the end of the runway, at which point the undercarriage separated from the airframe. The incident resulted in four injuries among the crew members. The aircraft sustained damage that rendered it a total loss.
Findings
While the specific reason for the initial engine failure remains undetermined, the primary factor in the runway excursion was the inability to stop the aircraft within the remaining runway distance following the mechanical malfunction.
