Many aircrafts of Indigo and GoAir were lying parked at the Indira Gandhi Airport.Passengers suffered a great deal in several places across the country.

Reason?Aviation Regulator Directorate General of Civil Aviation (DGCA) has cancelled their eight A320 Neo planes, each having faulty Prat & Whitney engines along with three such aircrafts of GoAir.

As a result,IndiGo was compelled to ground 47 of its 1,000-odd flights per day.This was admitted by the Wadia Group-promoted GoAir saying it had cancelled 18 flights.Even GoAir has cancelled 18 flights originating from over eight cities, said a PTI report.

As it is, GoAir operates 230 flights per day.

The flights that have been cancelled are from Delhi, Mumbai, Chennai, Kolkata, Hyderabad, Bangalore, Patna, Srinagar, Bhubaneswar, Amritsar, Srinagar and Guwahati, among others including Jharkhand capital.

Reports say that the DGCA has "cracked the whip after an IndiGo flight bound for Lucknow returned to Ahmedabad within 40 minutes of its getting airborne due to a mid-air engine failure on Monday."

The DGCA Director in its order dated  March 12 said that A320 Neos fitted with PW1100 engines beyond ESN 450 have been grounded with immediate effect .
