Airlines in India cancelled dozens of flights on Tuesday after the domestic aviation regulator grounded 12 Airbus A320Neo planes with faulty Pratt & Whitney engines, officials said.
IndiGo, the country's largest airline, cancelled 47 flights on its domestic network, the online edition of the Business Today magazine reported.
An IndiGo official said nine Airbus A320Neos were grounded leading to "dozens of flight cancellations."
A spokesman for budget airline GoAir also said it grounded three such aircraft following the regulator's order.
Hundreds of passengers have been stranded across India since Monday after flights were cancelled by the carriers following grounding of the 12 planes.
Citing safety of aircraft operations, the Directorate General of Civil Aviation in its order Monday said A320Neos fitted with P&W1100 engines were "grounded with immediate effect".
The regulator took action after the third in-flight shutdown was reported in recent weeks.
US-based Pratt & Whitney in a statement said it was working toward "minimising disruption."
"The corrective action has been approved and we have already begun to deliver production engines with the upgraded configuration," the company said, adding it was working to mitigate the situation by the end of the second quarter.
According to European aircraft manufacturer Airbus, a total of 113 P&W-powered A320Neo family aircraft were in operation in 18 countries worldwide. Airlines in India have ordered hundreds of the A320Neo family aircraft in recent years.
IndiGo has cancelled 47 flights on its domestic network.
