Mumbai: A Pune-Nagpur flight of IndiGo an Airbus A320 Neo was grounded soon after takeoff on Tuesday due to "excessive engine vibrations"--sixth such incident in the past two weeks alone, an airline industry source said.
The plane is powered by the already troubled Pratt & Whitney engine.
This is the sixth incident of midair glitches in the P&W engine-powered planes of IndiGo in the past two weeks alone, as the carrier continues to grapple with P&W engine issues even after three years of A320 Neo induction when the problem was first reported which led to grounding of several planes at frequent intervals.
Queries seeking a detailed response to these half-a-dozen incidents sent to the airline's chief spokesperson C Leekha, and Pratt & Whitney India head Palash Roy Chowdhury remained unanswered, while one of the airline spokespersons said the aircraft could not complete its journey and made a comeback after the pilot observed "engine caution" message.
