An Air India Airbus A320-200N, registration VT-EXO performing flight AI-2379 from Phuket (Thailand) to Delhi (India) with 137 passengers and 8 crew, was enroute at FL360 near position N21.33 E84.90 when the aircraft encountered severe turbulence causing altitude deviations of +175 feet followed by -250 feet before returning onto FL360 at about 09:33L (04:03Z). The aircraft continued to Delhi, where the aircraft landed without further incident about 90 minutes later. 13 passengers and 4 crew needed medical assistance.
The airline reported 13 passengers and 4 cabin crew received injuries.
India's Civil Aviation Ministry reported 8 passengers and 4 cabin crew were admitted to hospitals, all of them in stable condition. Flight data and cockpit voice recorder have been secured.
On Aug 10th 2026 India's DGCA reported that a transient technical fault caused the upset. The DGCA also stated that drug test on the captain has "not been negative" and needs confirmation. The occurrence is being investigated by India's AAIB.
On Aug 10th 2026 India's Pilots' Association reported that all three hydraulic systems failed. When the captain realized the triple hydraulic failure he instructed the first officer to take the nose of the aircraft down causing the loss of about 300 feet of altitude and a negative G-Load that caused the passengers to be thrown around the cabin. The crew had only a split second for the decision and could not have first switched on the fasten seat belt signs. The quick reaction by the crew saved countless lives on board.
On Aug 10th 2026 the airline changed their narrative of the accident now stating a "sudden loss of altitude during cruise" instead of inflight turbulence.
On Aug 13th 2026 a photo of the printed Post Flight Report (PFR) has surfaced (see below).
On Aug 13th 2026 India's media report that a second test of the captain was positive for Cannabis, too. The captain had been prescribed Cannabis by his family doctor to manage severe sleep difficulties. According to the media reports the captain told the AAIB that he had not slept well during his layover in Phuket and slept on board of the aircraft for about 30-35 minutes. He was pilot monitoring during the flight, the first officer was flying the aircraft.
In an assessment conducted by Airbus Airbus states, that the flight data recorder was successfully downloaded and decoded. According to the error code and FDR data the control of elevators and ailerons was lost for about 4 seconds:
at 04:02:44 the green hydraulic system failed causing a system reconfiguration
at 04:02:45 both blue and yellow hydraulic systems failed causing the total loss of both left and right hand elevators and total loss of ailerons. The right elevator shifted to +0.6 and the left elevator to -1.0 degrees. The ailerons, in dampening mode, started to deflect to their zero hinge moment, -13.6/-13.1 degrees leading to pitch increase of the aircraft.
At 04:02:51 the blue hydraulic system recovered, a few seconds later the yellow system and also the green system, the flight control surfaces were recovered.
This system behaviour is the consequence of the loss of hydraulic pressure.
On Aug 18th 2026 Airbus phoned The Aviation Herald and asked to remove the images of the Airbus paper to protect their copyright and confidentiality with customers, which we comply with.
On Sep 4th 2026 India's AAIB released their preliminary report describing the sequence of events:
On 04 August 2026, M/s Air Indias Airbus A320-251N aircraft bearing registration VTEXO, was scheduled to operate an International Flight AI-2379, from Phuket International Airport (VTSP) to Indira Gandhi International Airport, Delhi (VIDP). The Pilot-In-Command (PIC) of the flight was an ATPL holder, who was the Pilot monitoring (PM) and the Co-pilot was a CPL holder, who was the Pilot Flying (PF). There were 145 persons onboard (POB) i.e. 137 passengers (including 03 infants), 06 cabin crew and 02 flight crew.
Flight took-off at 01:41 UTC from Phuket airport and no abnormalities were reported. Subsequently, at 03:40 UTC, Flight AI 2379 entered Kolkata Flight Information Region (FIR) and contacted Kolkata ACC. Kolkata ACC, instructed the aircraft to climb from FL340 to FL360. The flight crew followed the ATC instructions and the aircraft climbed to the assigned FL 360.
At 04:02:43 UTC, while cruising at FL 360, aircrafts Flight control (F/CTL) system detected loss of green hydraulic system. Further at 04:02:47 UTC, Flight control (F/CTL) system detected loss of Blue and Yellow hydraulic system. At 04:02:48 UTC, the Autopilot got disengaged and Continuous Repetitive Chime (CRC) came. At 04:02:51 UTC, the Stall warning triggered for 2 seconds. The Co-Pilot, who was the Pilot Flying (PF) responded and tried to control the prevailing situation. Subsequently, PIC took over the controls. Meanwhile, the aircraft encountered altitude upset. Initially, it gained 372 ft and fell by 292 ft from its assigned FL360 during the event.
At around 04:02:52 UTC, the Blue hydraulic system was recovered, and few seconds later, the Yellow hydraulic and the Green hydraulic systems were also recovered. Consequently, this led to the recovery of the Flight control (F/CTL) surfaces. Subsequently, the aircraft operation returned to its normal operating condition.
At the time of the event, the aircraft was cruising at FL360 and seat belt signs were off. Consequently, some passengers and cabin crew suffered injuries. Cabin Supervisor apprised the cockpit about the injuries suffered by the passengers and cabin crew. The flight crew assessed the cabin situation and took the decision of continuing the flight to its planned destination i.e. Delhi airport and did not divert to the nearest enroute airport.
Later, the flight crew contacted ATC Delhi and sought medical priority. ATC responded accordingly and provided requisite assistance. At 05:30 UTC aircraft landed safely on runway 11 L at IGI airport, Delhi. Subsequently, aircraft taxied on its own power to the parking bay and parked at 05:37 UTC.
On arrival, at Delhi airport, medical assistance was provided to total 24 persons onboard (20 passengers and 04 cabin crew) by the airport medical team. Subsequently, they were shifted to nearby hospitals for further medical assessment. 20 persons were discharged after initial treatment for minor injuries. Remaining 04, who had received serious injuries were hospitalised for further treatment.
The aircraft sustained damages at several places inside the cabin mainly to the hatrack (overhead stowage bins) and ceiling panels.
The aircraft suffered damages limited to the cabin.
