Investigation Summary
The aircraft, a 28 year old Boeing 737-200 named White Nile, departed Port Sudan at 04:00 local time. Approximately 10 to 15 minutes after departure, the crew notified air traffic control of a power loss in one of the Pratt and Whitney JT8D-7 engines and initiated an emergency return. Weather conditions at the time included visibility restricted to 4 kilometers by blowing sand. Although the crew was cleared for an ILS approach to runway 35, reports indicate the pilot opted to attempt a visual approach to expedite the landing. Due to the dust storm, the crew failed to acquire the runway visually and lost situational awareness. During the transition to a missed approach or while attempting to realign at low altitude, the aircraft descended into the terrain and struck the ground in a desert area approximately 5 kilometers east of the airport. The impact and subsequent fire destroyed the aircraft.
Final Conclusions
The accident was triggered by a mechanical failure in one engine, followed by the crew's inability to successfully execute an emergency landing in poor visibility. The aircraft's disintegration upon impact resulted in the deaths of all but one passenger. Sudanese officials later attributed maintenance difficulties and a lack of spare parts to U.S. trade sanctions, though the immediate cause was the engine failure and subsequent controlled flight into terrain or loss of altitude during the emergency return.
