Kingdom, stated that pausing during evacuations "is just what we don't want people to do." Nevertheless, Muir acknowledged that photographs are "very valuable to accident investigators". Irregularities The final TSB report states: "During the flare, the aircraft entered a heavy shower area, and the crew's forward visibility was significantly reduced as they entered the downpour." This suggests the possibility that the plane was hit in heavy weather by a wet downburst, causing the Airbus to land long. Based on the Air France A340-313 Quick Reference Handbook (QRH), page 34G, "Landing Distance Without Autobrake", the minimum distance of would be used in dry conditions to bring the aircraft to a complete stop. In wet conditions the braking distance increases with a 5-knot tailwind, reversers operative, and a of downpour on the runway to . There was not enough remaining runway available at the touchdown point of AF 358. Other possible irregularities mentioned in a government report on the accident: Passenger oxygen tanks supposedly exploded in the heat of the fire. (Emergency passenger oxygen is provided via a chemical oxygen generator but the aircraft would have been carrying therapeutic oxygen for passengers requiring a constant supply throughout the flight and first aid situations.) The copy of the "E.R.S. Aircraft Crash Chart" at Pearson International Airport did not include blueprints for the Airbus A340 model of planes at the time of the accident. The blueprints would have contained vital information with regard to search and rescue efforts, and provide the location of fuel and pressurised gas tanks so that rescue crews could avoid them. Other irregularities that were not confirmed nor denied by officials: 12 seconds elapsed between the moment the plane touched down and when pilots applied the thrust reversers, which are used to assist braking One of the aircraft doors opened on its own during the landing, according to witnesses. Black boxes are unable to reveal this data. Conclusions The TSB concluded in its final report that the pilots had missed cues that would have prompted them to review their decision to land, and also that: Air France had no procedures related to distance required from thunderstorms during approaches and landings. After the autopilot had been disengaged, the pilot flying increased engine thrust in reaction to a decrease in airspeed and a perception that the aircraft was sinking. The power increase contributed to an increase in aircraft energy and the aircraft
