Canada’s transport regulator has asked Air India to investigate a pilot caught drunk at Vancouver International Airport. The pilot failed two breathalyzer tests and was asked to leave the aircraft. Transport Canada called the incident a “serious matter” in a letter to Air India. They may also take strict action against the airline. The pilot was removed from flying duties during the inquiry, Air India said. The flight from Vancouver to Delhi on December 23 was delayed, and a new pilot replaced the one under investigation. Air India said, “The pilot has been taken off flying duties during the process of enquiry. Air India maintains a zero-tolerance policy towards any violation of applicable rules and regulations.” According to a letter by Transport Canada official Ajit Oommen, Air India must share the probe results and steps to prevent reoccurrence by January 26. The news comes amid tough safety scrutiny after a Boeing Dreamliner crash in India killed 260 people on June 12. India’s aviation regulator recently issued warnings to four Air India pilots over “serious safety concerns” related to ignoring aircraft faults. The DGCA said pilots accepted a Boeing 787 aircraft for flight despite knowing about repeated technical issues. Air India is now under the spotlight for safety and pilot conduct both in India and abroad.
