Following engine woes, IndiGo grounds A320 neo aircrafts on DGCA instructions

Following engine woes, IndiGo grounds A320 neo aircrafts on DGCA instructions

Following engine problem warning, IndiGo has already grounded three A320 neo planes that are powered by P&W engines.

The Directorate General of Civil Aviationofficial said IndiGo has three such aircraft, which have been grounded. The agency ordered flight restrictions on planes powered by those engines: jets using two affected engines were ordered to stop flying them within three flight cycles; aircraft with one affected engine are restricted from certain extended-range flights.

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.

According to Pratt & Whitney, the latest issues do not involve engines for the Embraer E2 family and the Bombardier CSeries, but are limited to the Airbus application.

While investigation is ongoing to determine the root cause, preliminary findings indicate that the affected engines, which have high pressure compressor aft hub modification embodied from engine serial number (ESN) P770450, are more susceptible to IFSD.




Hawaiian Airlines said in a statement that it's identified one plane in its fleet - an Airbus A321neo -- that may be impacted.

Indian budget carrier IndiGo, said it had carried out 69 Pratt engines replacements in 18 months, after multiple inflight shut downs and turn backs, adding replacements were the best possible precautionary measure.

The performance problem with the engine performance is apparently new, but Pratt & Whitney has had ongoing issues with supply of new engines, leading to delivery delays and reduced revenue forecasts in recent years.

The A320neo specific PW1100G has been hounded with technical problems and reliability issues, while its variants were less affected.

"We are honoured by the continuing confidence that SWISS has placed in Pratt & Whitney and in the GTF engine", said Chris Calio, President, Commercial Engines, Pratt & Whitney.
