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 were killed.[2]

Accident

[edit]

The plane was operating a ferry and test flight from the Lukhovitsy Aviation Plant after some maintenance.[3] Four minutes after take off the plane made its last contact with the air traffic controller, and reached its maximum altitude of about 900 metres (2,953 ft).[4]

The plane crashed seven minutes after take off, about 80 kilometres (50 mi) south-east of its destination airport, near the city of Kolomna, in a wooded area killing all three crew members,[5][6][7] including two pilots and a flight engineer, all of whom were employees of Sukhoi.[3] According to Novaya Gazeta, the plane sent a distress signal and circled to burn fuel preparing to perform an emergency landing, before crashing.[8]

According to sources cited by Izvestia, the probable cause of the crash were malfunctioning angle of attack sensors installed during maintenance.[9] This was the fifth hull loss and third fatal accident of the Superjet since its introduction in 2011.[10]

According to the preliminary report the aircraft was flying at 5000 ft with a nose pitch angle between 5 and 6 degrees, the Air Data Computer 1 indicated an angle of attack between 10 and 11,5 degrees, while the second computer indicated an angle of attack between 11 and 13,5 degrees; the plane was cruising at a speed of 230 knots. The crew received the clearance to climb at 15000 ft, but the aircraft initially seemed to climb, but didn't do that and then seemed to be descending. So the first officer put the nose of the aircraft up to nearly 14 degrees, causing the autopilot to disconnect. After this the captain took control of the plane and accelerated to 270 knots, stopping the descent after the plan fell to 4500 feet. After starting to climb again the crew turned off the auto thrust and the plane reached 308 knots activating the overspeed warning, the crew then reported the unreliable speed to the ATC. Due to the excessive speed the plane initiated a nose up and activated the speed brakes. The climb stopped at around 4800 ft, but then the elevator put the nose down in an automatic maneuver to prevent an excessive angle of attack, so the plane started descending again. At 3000 ft the crew attempted to rise up the plane's nose again, but the elevators did not followed the command. After this descent the plane impacted the ground with a velocity of 365 knots.[11][12][13]

Aircraft

[edit]

The aircraft involved was a Sukhoi Superjet 100-95LR, MSN 95078, and registered as RA-89049. The aircraft was manufactured in 2014 and the flight consisted of three crew members, composed by Captain Evgeniy Bulavko, First officer Vladislav Kharlamov and Flight engineer Maxim Lukmanov.[4][8][14][15]

Investigation

[edit]

The investigation is being carried out by the Interstate Aviation Committee.[16] On the evening of 12 July, both flight recorders were found.[17] On 30 August 2024 the Interstate Aviation Committee released the preliminary report on the incident.[18]
