Passengers have also been offered refunds, IndiGo said. The European Aviation Safety Agency said Friday there were "several occurrences of engine in-flight shutdown" and other in-service events with the engine, and restricted their flight, the Journal said.
A senior official of Indigo confirmed receiving the recommendations by Pratt & Whitney as well as EASA with respect to the A320neo aircrafts powered by PW1100G-JM engines.
IndiGo is the largest operator of twin-engined A320 neo aircraft in the world; all their 32 neos are fitted with PW 1100 engines.
Airbus said it had informed affected A320neo customers and operators, adding there are now 113 Pratt & Whitney-powered A320neo aircraft flying with 18 customers.
Secondly, it has said that if an aircraft with at least one affected engine has operated one flight cycle after the directive was issued, it should not be allowed to conduct ETOPS operations.
"We have identified the potentially affected engines and communicated with our customers. As soon as IndiGo learnt of these developments, IndiGo had proactively withdrawn the three A320neo aircraft from service w.e.f. 9th of February", said the statement. "Safety of aircraft, passenger and crew at IndiGo is of highest priority and at no time it can be compromised with", the statement said. "Airbus and Pratt are working in close cooperation and will be swiftly communicating on the way forward to regain normal operations and resume aircraft deliveries", said the IndiGo statement.
Technical issues with certain engines of IndiGo's A320neo planes had led to the grounding of many flights previous year.
"The efforts of both companies are directed to support customers and operators to minimise any disruption", Airbus says, referring to itself and P&W.
The Pratt & Whitney engines are installed in about 113 Airbus planes across 18 airlines - the majority of which are in India and Europe, a Pratt & Whitney spokesperson told CNNMoney.
It was not immediately clear if the recent aft modification is related to the geared turbofan engine family's other known durability issues.
