The crew of a Su-30 fighter that crashed earlier on Tuesday in Russia’s Far East reported an engine fire before the crash, a spokesman for the Main Military Investigative Directorate said.

The Su-30MK2 fighter jet crashed 130 km northeast of Komsomolsk-na-Amure during a post-construction test flight. Both pilots ejected safely, although one of them was hurt on landing.

“While executing acceleration to a maximum speed, the first pilot reported a fire in the right engine,” the spokesman said. “The flight controller immediately ordered the crew to eject.”

“The investigators are taking all necessary steps to establish the cause of the crash,” the official said.

The aircraft belonged to the Komsomolsk-na-Amure factory where Su-30s are manufactured.

The Russian military earlier said that the plane had been built for export.

Su-family fighters constitute the bulk of Russia's arms exports.

Variants of Su-30 Flanker fighters are in service with air forces in several foreign countries, including India, Indonesia, China, Algeria, Vietnam and Venezuela.
