IndiGo has grounded an A320 neo aircraft at Lucknow due to problem in the Pratt & Whitney engine, according to a source. The aircraft has been grounded for maintenance since January 31.
P&W engine-powered A320 neos have been grappling with problems and aviation regulator DGCA has issued various directives to address these issues.
An IndiGo spokesperson Sunday said flight 6E-447 which was scheduled to operate on the Lucknow-Delhi route on January 31 was grounded as a precautionary measure.
A source said the flight was to be operated with an A320 neo plane.
"After taxi out the pilot noticed an error in the engine parameter. As a caution, he returned the aircraft to the bay," news agency PTI reported quoting a airline spokesperson.
The spokesperson said that after the inspection of the aircraft engine by the airline's technical team, the aircraft was grounded for further maintenance and engine would be changed.
