An Air India international service was delayed in Canada after authorities declared one of the pilots unfit for duty, raising serious aviation safety concerns. The incident occurred at Vancouver airport and led to an Air India flight delayed situation just before departure, following intervention by the Royal Canadian Mounted Police (RCMP).
What caused the Air India flight delay
The issue involved Air India Flight AI186, which was scheduled to operate from Vancouver to Delhi via Vienna on December 23, 2025. According to an official statement from the airline, one of the cockpit crew members was offloaded shortly before departure after Canadian authorities questioned the pilot’s fitness for duty. The RCMP conducted checks at the airport, which ultimately resulted in the Air India flight delayed due to safety protocols.

To ensure compliance with aviation norms, Air India arranged for an alternate pilot to operate the flight. While passengers faced a last-minute delay, the airline said the decision was taken strictly in the interest of operational safety.
Transport Canada flags safety violations
Transport Canada, in a letter dated December 24, 2025, addressed to senior Air India officials, confirmed that two breathalyser tests conducted by the RCMP found the pilot under the influence of alcohol and unfit for duty. The aviation authority stated that the incident leading to the Air India flight delayed amounts to violations of Canadian Aviation Regulations, including CARs 602.02 and CARs 602.03.

The letter further noted that the case also breaches conditions outlined in Air India’s Foreign Air Operator Certificate.
