Air India First Officer Suspended After Zurich Alcohol Test
An Air India first officer was scheduled to fly from Zurich to Delhi on September 6.
Staff at Zurich Airport noticed that he smelled of alcohol before the flight.
Authorities gave him an alcohol test, and he failed the first test.
Another test was conducted, but reports differed on whether its result had been received.
Other reports said later tests showed alcohol above the permitted limit.
The pilot was removed from the plane and sent back to India as a passenger.
He is suspended while medical checks and an investigation continue.
The flight could not leave as planned and was reportedly operated the next day.
The incident followed a separate case involving an Air India pilot who tested positive for marijuana.
An Air India first officer was removed from flight AI 151 at Zurich Airport on September 6 after staff detected the smell of alcohol.
The pilot failed a preliminary alcohol test and was sent back to India as a passenger while remaining suspended.
Reports differed on testing: a secondary result was still awaited, while subsequent tests reportedly indicated alcohol above the permitted limit.
Flight AI 151 could not operate as scheduled and was reportedly flown to Delhi the following day.
Swiss aviation authorities informed India’s DGCA, which asked Air India to strengthen safeguards amid scrutiny following a separate marijuana-related pilot case.
