AAIB reclassifies Air India Phuket-Delhi hydraulic failure as accident after 24 injuries
India’s accident investigator said three hydraulic systems failed within seconds on an Air India A320 flight from Phuket to Delhi. Tata Group-controlled Air India is cooperating and has ordered one-time mandatory drug testing for all pilots after the captain returned a non-negative psychoactive-substance result.

Why this matters
Potential partners and transaction counterparties will likely deepen safety-governance, maintenance and compliance diligence around Air India until the investigation clarifies root causes and remediation.
What to watch
- AAIB preliminary report findings on the hydraulic-system failure sequence, maintenance history and crew actions.
- DGCA audit outcomes, show-cause notices, mandatory inspections, fines or operational restrictions.
- Results of Air India's pilot drug-testing program and whether positive tests lead to suspensions or wider testing mandates.
- Evidence of similar hydraulic defects, repeat technical diversions, cancellations or elevated aircraft-on-ground levels.
- Changes in international booking trends, corporate travel-account retention, load factors and fare discounting on Air India routes.
- Tata Group commentary on incremental safety, maintenance, insurance or compensation costs.
- Expand mandatory alcohol and psychoactive-substance testing beyond the one-time pilot program, potentially including random testing and broader safety-sensitive staff.
- Conduct fleetwide inspections of A320 hydraulic systems, maintenance records, component suppliers and deferred-defect practices.
- Prepare a detailed regulator-facing corrective-action plan covering maintenance oversight, crew fitness-for-duty, training and incident reporting.
- Increase customer communications, flexible rebooking and compensation handling on affected routes to limit booking fallout.
- Accelerate hiring, training and quality-control investments, raising near-term turnaround costs but reducing future safety and brand risk.
