Description
On 8 July 2006, an A310 departed the runway at Irkutsk, Russia, at high speed following a mishandled landing while operating with one thrust reverser locked out. The aircraft impacted a barrier and buildings and was destroyed by a post-crash fire.
Synopsis
This is an extract of the "History of Flight" from the Interstate Aviation Committee Final Accident Report:
“On July 8, 2006 an А-310 airplane with state registration number FOGYP (France), leased by ОАО Aviakompania Sibir, and with a flight crew consisting of the Captain and the co-pilot, was flying scheduled passenger flight С7 778 from Domodedovo [Moscow] to Irkutsk…Note: 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.”
The Report makes the following conclusion:
"The cause of Sibir A-310 F-OGYP accident was the erroneous and uncontrolled actions by the crew during rollout after landing in a configuration with one engine reverser deactivated. After touchdown, the Captain, while acting on the reverse thrust lever of the right engine, inadvertently and uncontrollably moved the throttle lever for the left engine, whose thrust reverser was deactivated, from the "idle" to the significant forward thrust position. Inadequate monitoring and call-outs of airplane speed and engine parameters by the Co-pilot made it impossible for the crew to perform the necessary actions, either by moving the left throttle back to idle or shutting down the engines. The crew had enough time to recognize the situation…"
