Mumbai, Jan. 10 -- A Pratt & Whitney-engine powered A320neo plane of GoAir returned to the city due to "high engine vibrations" after an hour of its take-off for Delhi Thursday, a source said.

The plane, which had 168 passengers on board, made a safe emergency landing at the Chhatrapati Shivaji Maharaj International Airport here at 12.15 pm, he said.

The aircraft is out of operations, he added.

When contacted, a GoAir spokesperson said its flight G8319 made a turn back to Mumbai due to a "technical glitch".

"GoAir flight G8319 departed for Delhi from the Mumbai airport at 10.17 am. However, mid-air, one of the aircraft engines experienced high vibrations, forcing the pilot to seek ATC's permission to return to Mumbai," the source said...
