India’s aviation regulator on Friday imposed a fine of 3 million rupees (36,496 million dollars) on Air India.

The airline was fined after a pilot of the private airline was found violating safety norms by allowing a friend inside the cockpit during a flight.

The investigation into the incident was carried out after a complaint was filed by a cabin crew member of the Dubai-Delhi flight in February, the Directorate-General of Civil Aviation (DGCA) said.

The DGCA also suspended the licence of the pilot for three months.

Based on the complaint, the DGCA issued a show-cause notice to the private airline in April .

During the investigation, the DGCA found the pilot guilty of violating safety norms, and also warned the co-pilot for not being assertive in preventing the violation. (Agency Report: Text, Excluding Headline)
