New Delhi, India: India’s aviation watchdog has imposed a ₹20 lakh penalty on IndiGo for violating instrument flight procedure norms at Udaipur’s Maharana Pratap Airport, marking another compliance setback for the country’s largest airline.
According to a regulatory filing by InterGlobe Aviation, the parent company of IndiGo, the Directorate General of Civil Aviation (DGCA) found the airline in breach of rules after it implemented a Standard Instrument Departure (SID) and Instrument Flight Procedure (IFP) that had been internally formulated by the company rather than issued by the Airport Authority of India (AAI), the only authorised body to publish such procedures.
The DGCA stated that the airline’s actions violated Rule 133A of the Aircraft Rules, 1937, along with provisions of Civil Aviation Requirement (CAR) Section 9, Series C, Part I, specifically paragraphs 2.2 and 2.34, which mandate strict adherence to officially promulgated instrument procedures.
InterGlobe confirmed that the communication from the DGCA was received on 17 November 2025. In its exchange filing, the company noted that the penalty would have “no material impact” on its operations or financial position.
Industry observers say the latest order reflects DGCA’s tightening oversight on airlines’ compliance with flight procedures, especially at airports that require strict navigational conformity. Instrument departures and arrivals are critical for maintaining flight safety, particularly in regions with terrain challenges or high-density traffic.
The penalty comes weeks after DGCA imposed a ₹40 lakh fine on IndiGo for using non-qualified full-flight simulators to train pilots operating to Category C airports, including Leh, Calicut, and Kathmandu. The investigation revealed that nearly 1,700 pilots underwent training on simulators that did not meet regulatory standards prescribed for operations into these high-difficulty airports.In that case, DGCA penalised IndiGo’s Director of Training and Director of Flight Operations with individual fines of ₹20 lakh each, citing oversight lapses and deviations from CAR guidelines.
