Mumbai: The Gurugram-based budget carrier IndiGo on Sunday grounded one more A320 Neo fitted with Pratt&Whitney engine due to "oil chip issue" taking the total number of such planes on the ground to seven.
IndiGo confirmed the grounding of the plane bearing registration no VT-ITK after completing its flight to New Delhi from Kochi on Sunday.
"VT-ITK (Neo) operating COK-DEL (Cochi-New Delhi) was alerted with an 'oil chip' message on engine no 1 post landing at Delhi. As a part of troubleshooting, aircraft was withdrawn at Delhi," IndiGo said in a statement.
