The listed crash cause is human factor. On July 8, 2006 an <U+0410>310 airplane with state registration number F-OGYP (France), leased by <U+041E><U+0410><U+041E> Aviakompania Sibir, and with a flight crew consisting of the Captain and the co-pilot, was flying scheduled passenger flight <U+0421>7 778 from Domodedovo to Irkutsk. Apart from the two cockpit personnel, there were 6 flight attendants and 195 passengers on board (of these, 2 worked for the company), which included 181 nationals of Russia, 3 of Germany, 3 of the PRC, 2 of Poland, 3 of Belarus, 2 of Moldova and 1 of Azerbaijan. The airplane's payload according to the flight manifest was 19,800 kg (which included about 80 kg of hazardous freight - perfume), its take-off weight 140414 kg (maximum permissible – 150,000 kg), and center-of-gravity position 25.5% (the range of permissible center-of-gravity positions for take-off is 18% - 32%). Upon completion of the pre-flight preparation, the crew took off from Domodedovo airport at 17:17 (17:15 – as per schedule) and after climbing set a course for its destination airport of Irkutsk (alternate airport Bratsk). The flight proceeded without incident and at 22:17 the crew initiated descent for an approach and landing at Irkutsk airport. At 22:43:40 the airplane landed without misalignment on runway 30 at Irkutsk airport. Before the flight, in accordance with Sibir’s MEL, the maintenance personnel deactivated the thrust reverser on the airplane's left engine after hearing the crew's observation about this thrust reverser's malfunction during a previous flight. After touchdown all spoiler sections prepared ("armed") by the crew for utilization were deployed and the autobrake in Low mode, previously selected by the crew, was activated. The pilot moved the right engine (no. 2) thrust reverser forward. However, simultaneously with the subsequent reduction of the reverse mode of engine no. 2, engine no. 1 started to speed up (forward thrust), which led to an increase in airplane speed and the onset of torque that pulled the airplane to the right. The crew failed to perceive the cause of what was happening. In spite of intense wheel-braking efforts, the airplane used up the entire length of the runway and overshot its end at a speed of about 180 kph. The airplane then continued to travel on wet soil. At a distance of about 300 m from the departure threshold of the runway, the airplane collided with a concrete barrier of the aerodrome and then with some garages located directly behind the barrier, after which the airplane, now seriously damaged, stopped. As a result of the destruction of the fuel tanks the fuel ignited and fire penetrated the airplane's interior. As a result of the accident, 125 individuals died, including the two pilots and three of the flight attendants. The airplane was practically completely destroyed by the fire.

Aircraft reference details include registration F-OGYP, MSN 442, year of manufacture 1987.
