Air India has been fined over a crore over safety-related violations on flights operated on certain long-range terrain critical routes, the country's aviation regulator said today. The case pertains to leased aircraft not following performance limits laid down by the manufacturer. The Directorate General of Civil Aviation (DGCA) said it opened a probe after an airline employee voluntarily flagged the violations. The probe revealed "non-compliance by the airline", prompting a show cause notice to the airline, and ultimately the penalty.
