Canadian authorities have asked Air India to investigate an incident where a pilot allegedly reported for duty under the influence of alcohol and failed two breathalyzer tests at Vancouver International Airport on December 23. The pilot was removed from the flight, causing a delay, and has been taken off flying duties pending an inquiry. Transport Canada has deemed the incident a violation of Canadian Aviation Regulations and indicated potential enforcement action. Air India confirmed the delay, stated it is cooperating with authorities, and maintains a zero-tolerance policy for rule violations, promising strict disciplinary action if confirmed.
