On August 4, Air India flight AI2379 was cruising over Odisha at more than 36,000 feet when it suddenly lost around 300 feet of altitude. Passengers were thrown against seatbelts and overhead bins; by most accounts, somewhere between 17 and 20 passengers and four cabin crew were injured. The co-pilot took control, steadied the aircraft, and landed it safely in Delhi. A week later, the reason for the scare came into focus: the pilot-in-command has failed a confirmatory laboratory test for marijuana, following an initial screening that flagged concern and a cabin crew complaint alleging he was “high” in the cockpit.
If that sequence of events holds up once the Aircraft Accident Investigation Bureau completes its inquiry, it will be one of the more alarming aviation safety stories India has produced in years — not because of the injuries, which were relatively contained, but because of what it implies about how close the system came to missing it entirely.
The safeguard that almost didn’t work
What should trouble readers most is not simply that a pilot may have flown impaired. Individual failures of judgment happen in every profession, including ones where lives are on the line. What matters more is how the system responded, and how narrowly it worked. It was not routine ground-based drug screening that caught this — pilots typically undergo those checks before flights, and this one apparently passed muster to be at the controls. It was the co-pilot’s alertness during an actual emergency, and the cabin crew’s willingness to file a complaint afterward, that triggered the psychoactive-substance testing which ultimately caught the problem. In other words, the safeguard that worked was a human being noticing something was wrong mid-crisis, not the institutional check that was supposed to prevent the crisis from developing in the first place.
That is not a reassuring finding. A screening regime that depends on a co-pilot’s real-time judgment and a crew’s willingness to report a colleague, rather than catching impairment before departure, is a regime with a serious gap in it — one that, on a different day, with a less attentive co-pilot, could have ended very differently.
This is not an isolated data point
Context matters here, and it is not favourable to Air India. This incident follows a string of altitude and technical scares across the airline’s fleet in recent months, including a nearly 900-foot mid-air plunge on a Delhi-Vienna route, alongside the catastrophic Ahmedabad crash that has kept the airline under sustained regulatory and public scrutiny. DGCA safety audits earlier this year had already flagged maintenance deficiencies and delayed defect rectification across the fleet. None of those prior incidents are directly related to this one, but taken together they describe an airline whose operational and safety culture has been repeatedly questioned by its own regulator, not just by outside critics — and a pilot flying impaired now sits inside that same pattern.
What accountability should look like here
Under the Directorate General of Civil Aviation’s own rules, a confirmed positive drug test carries serious consequences: grounding, mandatory rehabilitation, and potential criminal liability if investigators establish actual impairment during active duty. Those rules exist precisely for a case like this one. The test now is whether they are applied with the seriousness the incident deserves, or whether the pilot quietly cycles through a rehabilitation process and returns to the roster once the news cycle moves on — a pattern not unfamiliar in how aviation lapses in India have sometimes been handled in the past.
The Civil Aviation Ministry has, to its credit, been careful in its public statements, insisting that no conclusion should be drawn before the AAIB’s investigation is complete and treating the medical evidence as protected pending that process. That caution is appropriate for determining exactly what went wrong. It should not become a reason to slow-walk the more basic accountability question: how a pilot who has now failed two drug tests was in the cockpit of a commercial aircraft carrying 137 passengers in the first place, and what specifically in Air India’s pre-flight screening allowed that to happen.
The real fix isn’t one pilot’s punishment
Grounding this particular pilot, whatever the investigation ultimately concludes about the cause of the altitude drop itself, addresses only the immediate case. The harder, more consequential question is whether India’s pre-flight psychoactive substance screening is rigorous and consistently enforced enough to catch impairment before an aircraft leaves the ground, rather than relying on a co-pilot’s alertness during turbulence at 36,000 feet to catch what should never have made it past the tarmac. Until that gap is closed, this incident will be remembered less as one pilot’s failure than as a warning about how much the system currently depends on luck.
