Russian Sukhoi SU-57 plane, which was not monitored by radars, crashed during a test flight in Russia’s far east in remote Siberian woodland after the pilot flew it away from a city and bailed out to safety with his ejector seat, on Tuesday. It was the first accident of its kind for the most advanced Russian warplanes, according to the United Russian Aircraft Corporation (UAC), a subsidiary of Russian aerospace and defense corporation.
The company said that the accident occurred in the Khabarovsk Krai region and that the pilot jumped parachute safely.
TASS news agency quoted two military sources as saying that the Russian Defense Ministry will form a committee to investigate the accident, which appears to be caused by a malfunction of the plane’s guidance system or pilot’s error.
UAC said that no one was injured on the ground in Su-57 crash.
Interfax news agency, citing a source, said the plane was one of the first of this type to be mass-produced and was scheduled to be delivered to the Russian Air Force by the end of this year.
Russia had previously tested the SU-57 in Syria.
A first prototype of this aircraft appeared in the air in January 2010 and was considered a competitor to the American F-22 Raptor, and the SU-57 appeared for the first time during the annual military parade in the Red Square in Moscow in May last year when two planes of this type broke the sky above the Russian capital.
Ten of the jets have already been built at Sukhoi’s plant in Komsomolsk-on-Amur for Pre-production tests and combat evaluation.

Some of them have been flown in combat during Russia’s military campaign in Syria, and the remainder are due to be delivered by 2028.
The unnamed pilot radioed he was in trouble and took the plane away from Komsomolsk-on-Amur and surrounding suburbs and villages, say reports.
