IndiGo to replace P&W engines on its fleet Airbus A320neo planes

The airline must replace all Pratt & Whitney engines in its fleet of almost 100 twin-engined Airbus A320neo planes.

The story can be read here but in summation, IndiGo has been ordered to replace the engines by India's air safety watchdog .

Are they the only airline that has those powerplants on their A320neos?

Found a 2017 link to Spirit Airlines (US) that had the same engine problems: https://airwaysmag.com/airlines/repo...gine-troubles/

Er, no, around 40% of the world's A320neo fleet is PW-powered.

There also has no decision yet been made about the engine option of the just ordered 300 A320-family aircraft, probably these issues let IndiGo tend in favour of the LEAP

Not all of the engines just over half.

so are the other airlines having the same number of failures and is there any common cause???

Sorry, I don't have access to that information.

Could be a batch problem, maintenance practices, operational choice or combinations. The manufacturer likely has a handle on this and the problem is getting addressed

Anyone know if any US aircraft have seen this issue?
 

Why has the FAA not taken similar actions on US aircraft?

Reading the article, this seems to be more of a modification. So what is so special about the way Idiego or, for that matter, GoAir operate or maintain their engines?
