Three seconds after lift-off from Runway 14 at Irkutsk, the No.3 engine surged at approximately 5 m ft out altitude. The aircraft continued to climb, but at a high angle of attack, disrupting airflow to No.1 and No.2 engines which also surged. Unable to continue climbing the aircraft descended until it struck houses in Mira Street, 1600 m ft yd out beyond the runway end, killing all 23 on board and 49 persons on the ground.Velovich Alexander Multiple engine failure blamed for An-124 Irkutsk accident https://www.flightglobal.com/news/articles/multiple-engine-failure-blamed-for-an-124-irkutsk-accident-30764/ FlightGlobal Flight International 15 November 2017 https://web.archive.org/web/20170612205346/https://www.flightglobal.com/news/articles/multiple-engine-failure-blamed-for-an-124-irkutsk-accident-30764/ 2017-06-12 1997-12-176 December 2007 Катастрофа самолета Ан-124 в Иркутске (1997 г.)

At 14:42 IKT aircraft took off from Irkutsk. However, just three seconds after lift-off from the runway at a height of 5 m ft, there was a surge in engine number 3 which caused an increase of the angular velocity of the Antonov. This resulted in a shutdown of engine number 2. Eight seconds after takeoff at the altitude of 66 m ft, following a surge in engine number 1, the aircraft began losing altitude. Although the pilots had tried to maintain control over the aircraft with a single remaining functioning engine, the aircraft crashed into apartment block number 45 on Grazhdanskaya Street. The tail section of the Antonov significantly damaged block number 120 and a neighboring orphanage.http://war.airdisaster.ru/database.php?id=5 An-124-100 Crash on 6 December 1997 Air Disaster Russia 17 January 2017 Russian Aftermath The crash resulted in the deaths of all of the crew on board the aircraft as well as 49 people on the ground (including 12 children from the orphanage). More than 70 families were left homeless due to the damage dealt on the two blocks by the crashed aircraft. The damage was aggravated by the ignition of tons of aviation fuel leaked during the crash.thumb|Workers amongst the wreckage Investigation A special commission was established to investigate the causes of the disaster. The two flight recorders, including the cockpit voice recorder, were in the center of the fire and were too badly damaged to provide meaningful data. The cause of failure of the three engines was never fully confirmed and the final conclusion of the commission has not been made public.Катастрофа Ан-124 ВВС РФ в пос.Иркутск-2 (борт RA-82005), 06 декабря 1997 года The crash of the Russian Air Force An-124 in Irkutsk-2 (aircraft RA-82005), December 6, 1997 http://war.airdisaster.ru/database.php?id=5 2021-09-22 war.airdisaster.ru ruJanuary 2025 However, temperatures in Irkutsk were below -20 °C °F and it was theorized that the disaster was caused by mixing cold-weather fuel with regular fuel, which was present in the tanks of An-124 after previous flight from Vietnam. That mix would have produced ice crystals which would clog the fuel filters, which would cut the fuel flow to the engines. In an interview with the Moskovsky Komsomolets newspaper, the test pilot Alexander Akimenkov said that the accident could have been caused by the call of a passenger with the Chinese radiotelephone, which affected how the electronics work.Як-42 погубил телефонный звонок?

Based on the results of this enterprise research and experiments and his own theoretical calculations, he concluded that the disaster situation was caused by high (in excess of standard) water content in the aviation fuel (kerosene) that resulted in the ice formation and clogging the fuel filters, causing the engines to surge.I cannot be silent anymore about the Irkutsk disaster.
