On 29 June 2009, an Airbus A310-300 making a dark-night visual circling approach to Moroni crashed into the sea and was destroyed. The Investigation found that the final impact had occurred with the aircraft stalled and in the absence of appropriate prior recovery actions and that this had been immediately preceded by two separate GWPS 'PULL UP' events. It was concluded that the attempted circling procedure had been highly unstable with the crew's inappropriate actions and inactions probably attributable to their becoming progressively overwhelmed by successive warnings and alerts caused by their poor management of the aircraft's flight path.
