A series of in-flight engine failures had prompted the aviation regulator DGCA on March 12 to order the immediate grounding of Airbus A320neo aircraft fitted with certain Pratt & Whitney (P&W) engines.
"You may have seen that the Indian authorities took a decision to ground the fleet in India that have engines of this... We're disappointed with that decision, but I can tell you that by the end of April, that fleet will be back up in the air flying in India," Pratt & Whitney president Robert F Leduc said during an interaction with United Technologies Corporation's (UTC) investors. P&W is a subsidiary of UTC.
"So I think the three key points that you should take away is we're back in production, we're going to retrofit and rework the 55 engines that we shipped previously back to Airbus. We will make our full year production commitment to Airbus," Mr Leduc said.
Eight aircraft operated by IndiGo and three by GoAir are affected by the directive from the Directorate General of Civil Aviation (DGCA).
On March 15, IndiGo and GoAir posted a curtailed flight schedule on their websites, saying they won't operate over 600 flights between March 15 and March 31. Of this, IndiGo has cancelled 488 flights.
The affected engine, PW1100, has a seal that causes vibrations and the issue had frequently led to in-service shutdowns, the DGCA has said.
In February, the US aviation regulator said the P&W engines pose a shutdown risk, following similar action by European regulators that month.
