Investigation Summary
The flight was operating a scheduled service from Beirut to Muscat with a stopover in Dubai. During the departure from Beirut International Airport, the flight experienced significant delays. The bomb, reportedly planted by militants, was likely equipped with a timer set for a specific duration after departure or a specific time of day. Because of the departure delay, the timer expired while the aircraft was still at its cruising altitude of 37,100 feet (11,300 meters) during the leg toward the United Arab Emirates. The resulting blast compromised the forward fuselage structure, leading to an immediate and catastrophic structural failure. The investigation was complicated by the ongoing Lebanese Civil War and the remote nature of the crash site in the Saudi desert.
Final Conclusions
The disaster was caused by the detonation of an explosive device in the forward cargo compartment. The perpetrators were never officially identified or brought to justice, though Omani militants were the primary suspects. The high death toll was an unintended consequence of the flight's delay, which shifted the explosion from a ground-based event to a mid-air catastrophe.

Systems & Failure Modes
Forward Cargo Hold
The location where the explosive device was planted, leading to the breach of the pressurized fuselage.
Fuselage Structure
The airframe failed catastrophically due to the internal pressure differential and the force of the blast at high altitude.
