Investigation Summary
The flight was a multi-leg international service originating in Brazzaville, Congo, with a final destination of Paris, France. Scheduled intermediate stops included Bangui (Central African Republic), Fort Lamy (now N'Djamena, Chad), and Marseille (France). The aircraft departed Fort Lamy for the trans-Saharan leg of the journey. At 23:10 UTC, the crew reported that the flight was proceeding normally at 20,000 feet. Shortly thereafter, an Air France pilot who flew over the site reported being told by frontier guards that they had seen a ball of fire tumbling from the sky. The aircraft impacted the Great Eastern Sand Sea; reports on the exact location vary between 35 miles from the Edjele oilfield and 100 km north of Edjele, near the Algerian-Libyan border. Investigation of the wreckage revealed that the empennage (tail assembly) had separated from the fuselage in flight. Chemical analysis later indicated the presence of nitrocellulose explosives, confirming that the structural failure was the result of a deliberate bombing rather than a mechanical fault.
Final Conclusions
The investigation concluded that the most probable cause of the crash was sabotage involving a nitrocellulose explosive device. The detonation caused the immediate failure of the aircraft's empennage, leading to an in-flight breakup. Although rumors circulated regarding the assassination of Central African Republic ministers on board, no group claimed responsibility, and no individuals were ever arrested or charged in connection with the bombing.
