InterGlobe Aviation Ltd, operator of IndiGo, said on Wednesday it grounded five Airbus A320neo aircraft at New Delhi airport after issues with their engines manufactured by United Technologies' Pratt & Whitney.
The aircraft are expected to be back in service in the second half of August, InterGlobe Aviation said in a statement.
India's aviation regulator in March had ordered immediate grounding of Airbus A320neo aircraft fitted with certain Pratt & Whitney engines.
InterGlobe shares fell 3.2 percent to their lowest in 14 months in afternoon trade in Mumbai.
