ZHUKOVSKY, Russia (AP) — Russia's first stealth fighter jet had to abort a takeoff at Moscow's International Aviation and Space Show on Sunday because of what officials said was a malfunction in the right engine.
The T-50 did not leave the runway and was slowed by a brake parachute.
The twin-engined jet was traveling at 60 miles per hour (100 kph) when the pilot decided to abort takeoff because of a right engine malfunction, the RIA Novosti news agency reported, citing a representative of United Aircraft Building Corp., a state-controlled holding that incorporates top Russian aircraft-makers,
The T-50, which made its maiden flight in January 2010, had been kept out of the public eye before its debut at the air show on Wednesday during a visit by Prime Minister Vladimir Putin.
The fighter is intended to match the U.S. F-22 Raptor, which entered service in 2005.
The T-50 still lacks new engines and state-of-the art equipment, and its serial production is only expected to begin in 2015 at the most optimistic forecast. Two T-50s are currently undergoing tests, and another pair is expected to join them later this year.
Russia has signed deals with India to cooperate on the aircraft's development, and hopes that the Indian air force will become a major customer for the plane.
The six-day air show at the Zhukovsky air base outside of Moscow wrapped up on Sunday.
