India's civil aviation watchdog has pulled up the country's most profitable airline, Gurgaon based budget carrier IndiGo, for flouting safety norms on a number of occasions. 

Some of these breaches are of a serious nature, according to a financial audit report by the Directorate General of Civil Aviation, or DGCA, and may lead to a regulatory review of the airline's expansion plans. 

"Fast growth induction plan of the fleet in the organisation also needs to be reviewed in view of the serious findings recorded in audit reports," the DGCA report says, referring to IndiGo's plans to expand its fleet to 55 aircraft by the end of this financial year. 

Insisting that its fleet expansion plans will continue, IndiGo president Aditya Ghosh said, “It would be a joke to tell the world that a country of more than one billion has 400 planes and there is overcapacity. We need to double the capacity. We have less than one-fourth of planes compared to Philippines.”

“Even airlines that have larger fleets compared to us are adding capacity.”

Ghosh said these were initial observations and that they had made a detailed presentation to the DGCA and believed that the regulator is satisfied with it. “There is no question of us not reporting a snag,” Ghosh added.
