On Wednesday, the head of aircraftmaker Airbus said U.S. engine maker Pratt Whitney has been struggling to support its fleet of passenger jets with enough spare parts and engines.
Go First's CEO Guillaume Faury declined comment on a decision by the third-largest airline, Go First, to file for bankruptcy, which it blamed on problems with Pratt Whitney's GTF engines on its Airbus 320 neo jets.
There are issues with in-service support of the GTF that are leading to airlines having planes with temporary issues, and planes 'AOG' grounded and this is something that we are very closely monitor, he said.
Pratt Whitney, Raytheon Technologies' chief executive, did not immediately respond to a request for comment.
The world's largest aerospace contractor said last week that time on the wing - the period between maintenance visits - had improved but was not yet at the level we and our customers expect.
