Air India A320neo Hydraulic Failure Prompts Pilot Fitness Concerns
Published on 09/04/2026 at 11:37 | Editorial boerse-global.de
A mid-air emergency on an Air India flight has raised serious questions about aviation safety protocols, after investigators confirmed a total hydraulic system failure and flagged concerns over the pilot's fitness for duty. The findings, published in a preliminary report by the Aircraft Accident Investigation Bureau (AAIB), carry implications for airlines and regulators worldwide, including UK operators who face similar scrutiny over crew welfare and maintenance standards.
Triple Hydraulic Failure at 36,000 Feet
On August 4, 2026, Air India flight AI 2379 was cruising from Phuket to Delhi at 36,000 feet when all three of its hydraulic systems failed simultaneously. The Airbus A320neo, registered as VT-EXO, suddenly gained 372 feet before dropping 292 feet — a violent altitude upset that triggered a stall warning.
The abrupt movements occurred while the seatbelt signs were off, compounding the risk to passengers and crew in the cabin. The AAIB confirmed the triple hydraulic failure as the primary mechanical cause of the instability.
While aviation incidents grab headlines, workplace safety failures on the ground are far more common — and often just as costly. UK employers have a legal duty to protect staff and visitors under the Health & Safety at Work Act 1974, yet many unknowingly fall short on documentation. A free toolkit provides nine ready-to-use tools, including risk assessments and compliance checklists, to help you close those gaps before an incident occurs.

Injuries and Crew Conduct Under Scrutiny
The incident left 24 people injured: 20 passengers and four crew members. While the mechanical failure explains the aircraft's erratic behaviour, the investigation has also turned its attention to the flight deck.
The Pilot in Command (PIC) tested non-negative for psychoactive substances following the flight — a finding the AAIB described as a matter of serious concern for aviation safety. The revelation has prompted questions about how such a breach could occur, given the strict medical and fitness requirements placed on commercial pilots.
Regulatory Action Recommended
The AAIB has recommended that the Directorate General of Civil Aviation (DGCA) take formal action in response to the findings. The investigation remains ongoing as authorities work to establish the root cause of the total hydraulic loss and examine how the flight crew's conduct slipped through existing safeguards.
Just as airlines must verify pilot fitness, every UK business must ensure its safety procedures are current and enforceable. Over 37,000 UK companies already use a free Health & Safety Toolkit covering everything from fire safety to PPE and first aid — all aligned with current regulations. Don't wait for an inspection to reveal what's missing. Get the free Health & Safety Toolkit
For UK airlines, the case serves as a reminder of the regulatory framework governing pilot fitness and the importance of robust reporting systems. Under UK law, pilots are subject to strict medical oversight, and any substance misuse is treated as a serious breach of safety obligations.
