On August 4, 2026, Air India Flight AI-2379—an Airbus A320 carrying 137 people from Phuket to New Delhi—suffered a sudden 300-foot altitude plunge during its cruise phase, injuring 24 people. According to internal safety reports and subsequent investigations covered by outlets like NDTV and Kompas.com, the pilot-in-command later tested positive for marijuana, triggering intense scrutiny over cockpit safety protocols.
Inside the Cockpit During the Phuket-to-Delhi Plunge
The chaos onboard Flight AI-2379 unfolded in a matter of seconds while the aircraft was cruising at altitude. According to an internal Air India Flight Safety report accessed by NDTV, the captain was standing behind the first officer’s seat at the time, discussing the jet’s air conditioning system. Suddenly, aural and Electronic Centralised Aircraft Monitor (ECAM) alerts erupted in unison, warning that the Airbus A320 was approaching a stall condition.
The autopilot disengaged automatically, and the aircraft’s nose pitched upward. Responding to standard stall-recovery protocols, the first officer at the controls pushed the nose down sharply to build airspeed. Here is why that matters: that aggressive maneuver produced a severe negative-g excursion. The plane accelerated downward faster than gravity, rendering anything unstrapped—including the crew and the standing captain—temporarily weightless and floating inside the cockpit.
Engineering logs reviewed by investigators revealed a deeper mechanical strain during the rapid recovery. Within the exact same minute, the aircraft registered low pressure warnings cascading from the Green hydraulic system to the Blue and Yellow systems, alongside a left/right elevator fault. While the crew managed to stabilize the aircraft and ultimately land safely in New Delhi, the incident left 20 passengers and four crew members injured.
The Drug Testing Controversy and Cabin Crew Testimony
Following the harrowing flight, both pilots were subjected to mandatory psychoactive substance testing. Initial screening results for the pilot-in-command required secondary confirmation, and subsequent laboratory analysis confirmed that the pilot was positive for marijuana. Consequently, both crew members were immediately grounded pending ongoing investigations by civil aviation authorities.

Reports from the Times of India, cited by Kompas.com, added troubling context regarding the pilot’s behavior during the journey. Cabin crew members alleged that the pilot-in-command spent time sitting on the cockpit floor and displaying uncharacteristic behavior that left him unable to walk normally upon disembarking.

Broader Implications for Aviation Oversight
This incident represents a significant stress test for regional carrier safety frameworks and pilot health monitoring across South Asia. DW.com noted that this event arrived amid a particularly turbulent week for Indian aviation, amplifying public anxiety over routine commercial travel.

Ensuring stringent enforcement of drug and alcohol policies is vital for maintaining passenger trust globally.
As investigations continue into the cascading hydraulic warnings and the pilot’s positive drug screen, the international aviation community will be watching New Delhi closely. Let us know your thoughts in the comments below.
