A critical safety breach has led to the immediate grounding and disciplinary action against a commercial flight officer on an international route. An Air India co-pilot assigned to operate a scheduled passenger service from Zurich, Switzerland, to the Indian capital of Delhi was placed under immediate suspension after failing a mandatory pre-departure alcohol screening test. The disciplinary measure was initiated right at the boarding gate before the aircraft could push back, averting any in-flight emergency that could have jeopardized passenger safety.
The Pre-Boarding Incident at Zurich Airport
The incident occurred on September 6 at Zurich Airport, where Air India flight AI-151 was preparing for its scheduled departure to Delhi. Shortly before boarding and departure procedures were finalized, officials noticed signs indicating that the designated co-pilot might be under the influence of alcohol. Responding promptly to the suspicion, authorities administered an initial alcohol breathalyzer test. The preliminary screening returned a positive result, confirming that the flight officer had breached strict aviation safety codes prohibiting alcohol intake prior to operating an aircraft.
Following the positive outcome of the initial test, the co-pilot was instantly grounded and barred from entering the cockpit. Local officials in Zurich subsequently administered a secondary medical test to determine the exact alcohol content, the laboratory report of which is currently awaited. In the meantime, the airline stripped the crew member of all active operational duties and arranged for him to be flown back to India as an ordinary passenger. Administrative and aviation officials have affirmed that his suspension will remain in force until the final medical report is received and evaluated.
Flight Grounded and Rescheduled for the Following Day
Because the co-pilot was removed from duty at the eleventh hour, flight AI-151 could not take off according to its published timetable. Stringent international aviation regulations strictly forbid long-haul passenger operations without a fully certified and legally compliant complement of flight deck crew. With the carrier needing time to arrange replacement personnel, the aircraft had to remain on the tarmac overnight. The stranded flight finally departed Zurich for Delhi the following day, causing substantial schedule disruption for travelers.
Air India Reasserts Zero Tolerance for Safety Violations
Addressing the disciplinary measure, Air India stated that it maintains an uncompromising zero-tolerance policy toward any breach of safety regulations, flight procedures, or internal airline protocols. The management emphasized that whenever an infraction is confirmed, stringent punitive action is enforced in accordance with both statutory regulatory requirements and organizational policies.
The carrier also stated that it has reinforced accountability, strict regulatory compliance, and a safety-first operational culture across its ranks. Flight crew members have been reminded of their core obligation to uphold the highest benchmarks of professionalism, personal integrity, and flight safety. In addition to regular compliance training and awareness drives, the airline conducts mandatory screening programs designed to identify and eliminate the consumption of psychoactive substances among operating personnel.
Context of the Previous Marijuana Incident Involving AI-2379
This suspension follows closely on the heels of another alarming safety breach recorded just weeks earlier involving a different international flight operated by the carrier. On August 4, during the operation of flight AI-2379 from Phuket to Delhi, the passenger jet experienced a sudden altitude drop of approximately 300 feet while flying through Indian airspace over Odisha. The aircraft was carrying 137 passengers and eight crew members at the time of the sudden descent. The unexpected plunge resulted in injuries to more than 20 passengers and four crew members before the airliner stabilized and completed a safe landing in Delhi.
Subsequent medical evaluations carried out after that incident revealed that the pilot, identified as Sudeep Vashisth, tested positive for marijuana on two separate drug tests. Following the duplicate positive results, Vashisth was terminated from the airline. In his defense, Vashisth stated that personal circumstances had caused him severe sleep deprivation and insomnia, for which a family physician had prescribed him medication.
Strengthened Substance Screening Across the Airline
The severe incident over Odisha prompted Air India to mandate comprehensive new dope testing requirements covering all active commercial pilots. Furthermore, the carrier rolled out heightened operational safeguards, including mandatory testing for psychoactive substances, enhanced safety awareness programs, reinforced mandatory reporting protocols, and stricter day-to-day oversight of regulatory standards across the entire operational network.
