From the Wikipedia article
On 12 July 2024, a Sukhoi Superjet 100 operated by Gazpromavia as Gazpromavia Flight 9608 crashed during a ferry flight from Tretyakovo Airport to Vnukovo International Airport. All three crew members, who were the only occupants on board, were killed.
Accident
The aircraft was operating a ferry and test flight from the Lukhovitsy Aviation Plant after some maintenance. Four minutes after takeoff the aircraft made its last contact with the air traffic controller, and reached its maximum altitude of about 900 m.
The aircraft crashed seven minutes after takeoff, about 80 km south-east of its destination airport, near the city of Kolomna, in a wooded area killing all three crew members, the two pilots and a flight engineer, all employees of Sukhoi. According to Novaya Gazeta, the aircraft sent a distress signal and circled to burn fuel preparing to perform an emergency landing, before crashing.
According to sources cited by Izvestia, the probable cause of the crash were malfunctioning angle of attack sensors installed during maintenance. This was the fifth hull loss and third fatal accident of the Superjet since its introduction in 2011.
Investigation and cause
Investigation
The investigation is being carried out by the Interstate Aviation Committee. On the evening of 12 July, both flight recorders were found. On 30 August 2024, the Interstate Aviation Committee released the preliminary report on the accident. The Ministry of Transport said that the aircraft did not have permission to fly.
Final report
On 25 July 2025 the IAC released its final report. The accident had been caused by incorrect element installation of the speed and AOA protection systems. This caused the aircraft to dive into an uncontrolled dive with the pilots unable to regain control. The IAC also made some recommendations.
A source familiar with the situation told Izvestia that one of the engineers at the Lukhovitsy Aviation Plant installed two of the four angle-of-attack sensors with a deviation of approximately five degrees. This would have led to an (incorrect) activation of the stall warning system.
