Investigation Summary
The crisis began during boarding in Algiers when four men in police uniforms entered the cabin under the guise of an identity check. Suspicion arose when Algerian 'Ninja' special forces surrounded the aircraft, prompting the hijackers to reveal their weapons and explosives. The hijackers, led by Abdul Abdullah Yahia, demanded the release of imprisoned Islamic Salvation Front leaders. When the Algerian government refused to let the plane depart, the hijackers executed an Algerian police officer, a Vietnamese diplomat, and finally a French embassy cook, throwing their bodies onto the tarmac. French authorities, receiving intelligence that the hijackers intended to use the aircraft as a flying bomb over Paris, pressured Algeria to allow the flight to leave. The aircraft landed in Marseille with insufficient fuel to reach Paris. During negotiations in Marseille, the hijackers demanded a large quantity of fuel, far exceeding what was needed for the short hop to Paris, confirming fears of a suicide mission. The GIGN launched a tactical assault at dusk, using mobile stairs to board the aircraft simultaneously through multiple doors. However, the assault faced an immediate complication: the front starboard stairs were elevated too high for the door frame. The GIGN had trained on an empty aircraft, but the weight of the passengers and fuel had compressed the A300's suspension, lowering the door height. After a brief delay to reposition the stairs, the commandos entered the cockpit, which became the primary battleground where the hijackers were eventually neutralized after a 20-minute firefight.
Final Conclusions
The investigation concluded that the hijacking was a terrorist act by the GIA intended to cause a mass casualty event in Paris. Security at Houari Boumediene Airport was found to be insufficient, allowing the hijackers to bypass checks using stolen or forged uniforms and credentials. The successful resolution of the crisis was attributed to the tactical precision of the GIGN and the resilience of the flight crew, particularly Captain Bernard Dhellemme, who remained in the cockpit throughout the ordeal and the ensuing firefight.

Systems & Failure Modes
Cockpit Door
At the time of the hijacking, cockpit doors were not reinforced, allowing the hijackers easy access to the flight deck to control the crew.
VHF Radio
Used by the hijackers to communicate their demands to the Algiers tower and later by the crew to signal GIGN during the standoff.
Interesting Facts

Safety Actions & Advisories
Reinforced Cockpit Doors
The incident contributed to the eventual global movement to install bulletproof, locking cockpit doors to prevent unauthorized access.
Enhanced Ground Security
Air France suspended all flights to Algeria for ten years and implemented stricter identity verification for ground personnel.
