Circumstances:
On approach to Moroni by night, while the crew as starting a go around procedure, he lost control of the aircraft which stalled and crashed into the sea. Only one young girl survived the crash and was rescued 12 hours later while all 152 other occupants were killed.
Probable cause:
Accident was caused by inappropriate actions on part of the crew on flight controls which brought the aircraft into a stall that could not be recovered. These actions were successive to an unstabilised visual approach during which several alarms related to the proximity of the ground, the aircraft configuration and approach to stall sounded. Crew's attention was focused on the management of the path of the aircraft and the location of the runway, and they probably did not have enough mental resources available in this stressful situation, to respond adequately to these different alarms.
Contributing to the accident were the following factors:
- Weather conditions at the airport with winds gusting to 30 knots,
- Lack of training or pre-flight briefing of the crew in accordance with the Yemenia company operations manual, given the reluctance of the pilot to execute the MVI [Visual Manoeuvring with Prescribed track] (none of the documents submitted in the investigation shows this training),
- The non-execution of the MVI maneuver by the crew (the plane left the LOC axis after the published point which is 5.2 NM), implying that the crew delayed the turn to reach the right hand downwind leg.
- The non-application by the crew of the procedure following the PULL UP-alarm.
