Airbus halts deliveries of A320neo

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.

This is the second time that IndiGo has been forced to ground planes because of P&W engine problems.

In a major question mark on Pratt & Whitney (PW) engines being used on the Airbus A-320 new engine option (Neo) planes, the European Aviation Safety Agency () has issued an emergency airworthiness directive warning of a potential "dual engine" inflight shutdown on A320neo-family aircraft powered by PW PW1100G geared turbofan (GTF) engines. Last year, the carrier had to ground a few aircraft and they began flying again after the issues were fixed. But Airbus has still parked around 30 otherwise completed aircraft at its manufacturing sites in Toulouse and Hamburg awaiting engines.

Airbus says around one-third of the in-service fleet of A320neos and A321neos has those engines installed so far, 11 of which are understood to have all two engines of the problematic standard and 21 just one of them.

The issue is the latest in a string of problems that have bedeviled the GTF program.

The DGCA official said IndiGo has three such aircraft, which have been grounded.

India's IndiGo has grounded three jets, but regulators said its competitor GoAir is not affected.

A statement from IndiGo on Saturday said the precautionary measure of grounding the three aircraft "resulted in cancellations of some of our flights".

Low-priced carrier IndiGo, the country's biggest airline, has grounded three of its Airbus A320 new engine option (neo) aircraft, following a safety alert from the European aviation regulator EASA over some variants of the Pratt and Whitney engines used globally.

Noting that the issue is isolated to a limited sub population of engines, P&W said it has identified the potentially affected engines. However, if one engine fails, a twin engine aircraft like an A320 can safely land with the other operative engine. If an aircraft has only one engine with the aft hub modification, it must stop flying extended routes over water within one flight cycle, EASA says.

Pratt & Whitney, the engine manufacturer, is investigating the root cause of this new finding with the full support of Airbus.
