The DGCA in a statement said,"Out of the 11, eight are operated by IndiGo while GoAir operates three".
Pratt & Whitney said it's working closely with customers to minimize disruption and has begun to deliver engines with an "upgraded configuration", Bloomberg said. To be sure, only a handful of A-320 Neos in IndiGo and GoAir fleets have this specific series of PW engine.
"Both IndiGo and GoAir have been told not to refit these engines, which are spare with them in their inventory", the Directorate General of Civil Aviation (DGCA) said in a release. "We are working to mitigate the AOG (aircraft on ground) situation by the end of the second quarter". Following the EASA directive in February, Airbus had suspended the delivery of A320neo aircraft equipped with the affected engine model. "We have complied immediately", a GoAir spokesperson said.
Indigo said it was in receipt of the DGCA communication and would promptly comply with the same.
With this, all the A320neo aircraft with PW1100 engines beyond serial number 450 have been taken off operation in India. Officials went into a huddle soon after and emerged with the directive to ground these A320neo planes. According to the report, the move came hours after when an IndiGo aircraft took off from Ahmedabad for Lucknow on Monday and then had to make an emergency landing in Ahmadabad.
Besides today's incident, there were two - one with GoAir plane after take-off from Leh on February 24 and another was with IndiGo following take-off from Mumbai on March 5.
Earlier this year, the European Aviation Safety Agency (EASA) had called for the global grounding of Airbus 320 neo aircraft due to a few occurrences of aborted take-offs and in-flight shutdowns on aircraft fitted with the PW 1100 from Serial Number 450 and beyond.
It was forced to return to Ahmedabad airport, in western India, the airline, which is owned by InterGlobe Aviation, said in a separate statement.
There are around 45 A320 neos, powered by P&W engines, in the country.
IndiGo and GoAir have a total of 32 and 13 A320neos in their fleet, respectively.
