Investigation Summary
Eight minutes after departing Mogadishu for Hargeisa, the Fokker F-27 entered a localized area of intense thunderstorm activity. The aircraft was subjected to violent vertical gusts that led to a loss of control and a subsequent spiral dive. During the attempted recovery or the dive itself, the airframe was subjected to loads measured at approximately 5.76 g. The Fokker F-27's design stress limit was significantly lower than this value, leading to the catastrophic separation of the right wing. The wreckage fell near the town of Balad, and the post-impact fire was so intense that rescuers reported little hope of identifying individual victims.
Final Conclusions
The investigation concluded that the primary cause was an encounter with severe turbulence and vertical gusts that led to a loss of control. The resulting spiral dive induced G-loads (5.76 g) that exceeded the aircraft's structural design limits, causing the right wing to detach. Contributing to the accident was the flight crew's decision to take off into known thunderstorm conditions.

Operational Restrictions
Following the crash and reports of poor maintenance on the remaining fleet, the U.S. Ambassador to Somalia issued orders prohibiting American personnel from flying on Somali Airlines' remaining Fokker F-27.
Known Controversies & Unanswered Questions
Allegations of Coerced Flight
Reference ↗Former U.S. Ambassador Peter S. Bridges claimed the pilot initially refused to fly due to the aircraft's poor mechanical condition but was threatened with imprisonment by authorities if he did not take off.
Disputed Weather Conditions
Reference ↗Some local accounts and aviation experts disputed the official finding of a thunderstorm, noting that Mogadishu rarely experiences such weather in July, suggesting spatial disorientation as an alternative cause.
