New Delhi, Mar 12: The Directorate General of Civil Aviation (DGCA) on Monday directed public carriers IndiGo and GoAir to ground 11 Airbus A-320 New engine option (Neo) aircraft with immediate effect that are fitted with a faulty type of Pratt & Whitney (PW) engines. The directive came after an IndiGo A320neo VT-ITA flight, which took off from Ahmadabad for Lucknow, had to make an emergency landing owing to engine failure.

The DGCA in a statement said,”Out of the 11, eight are operated by IndiGo while GoAir operates three.” The regulator has also asked the two airlines not to refit these engines (PW1100 engines beyond serial number 450) which are spare with them in their inventory.

Earlier, the European Aviation Safety Agency (EASA) had issued an emergency airworthiness directive for A-320 Neos fitted with PW1100 engines (from serial number 450 and beyond). After this, three A-320s of IndiGo were grounded in India as these planes had both engines of the flagged type.

Earlier in the day, an aircraft of the US-Bangla Airlines crashed close to the Tribhuvan International Airport (TIA) in Kathmandu afternoon killing at least 50 passengers. The 78-seater aircraft was carrying 67 passengers when it veered off the runway while landing at 2.20 PM and crashed onto a ground near the airport, catching fire.
