DGCA, the aviation watchdog, had called an urgent meeting with with IndiGo and GoAir to review performance of Airbus Neo aircraft in the respective fleets.

DGCA's statement has been quoted by Times Now, "About 40 per cent of the domestic seat capacity of India is powered by Neo Engines and therefore, any knee-jerk reaction to completely shut their operations will have serious consequences. As there has not been any reported case of any accident in any part of the world, where these engines are in operation, will it be prudent?"

The aviation regulator has also admitted that there have been cases of Air Turn Back, in-flight shutdown or engine vibrations.

"DGCA is continuously monitoring the performance of these engines and taking appropriate proactive measures as and when required including grounding of aircraft in the interest of safety and further remedial measure if necessitated, will be taken. The operation of these aircraft/ engines are considered safe globally. Manufacturer has been directed to ensure more availability of spare engines for Indian operators to prevent grounding of aircraft due to removal of engines," the regulator added as quoted by the media.
