Budget carrier IndiGo on Sunday said that one of its A320neo aircraft that had operated on the Kochi - New Delhi route on Saturday was withdrawn here for a maintenance check to attend to a reported defect.
"VT ITK (NEO) operating COK - DEL (Kochi - New Delhi) was alerted with an 'oil chip' message on engine #1 post landing at Delhi, " the airline said in a statement.
"As a part of troubleshooting, aircraft was withdrawn at Delhi.
This is a known issue with a prescribed solution.
This is not engine failure.
Including this aircraft, IndiGo now has seven 'NEOs' grounded. "
