Four more IndiGo planes with P&W-engines face glitches

MUMBAI : Glitches with Pratt & Whitney engines began to dog IndiGo again with four more A320s and A321s reporting one issue or other between Sunday and Tuesday, according to a source.

Besides, the airline is reportedly deploying a few planes powered by P&W engines for daily operations despite those planes earlier reporting heavy engine vibration, the source added.

However, a senior DGCA official rebutted the allegations saying “some engines, which reported vibrations were within the limits prescribed by the US and European aviation safety regulators and they have been released for operations after boroscopic inspection.”
