A devastating crash of Air India Flight AI 171, a Boeing 787‑8 Dreamliner (registration VT‑ANB), on June 12, 2025, near Ahmedabad resulted in the deaths of 241 passengers and crew, along with dozens of people on the ground—leaving only one survivor. The incident has triggered a sweeping safety review, leading to widespread flight cancellations and regulatory scrutiny.
Investigation: Fuel Switch Error Under Scrutiny
Preliminary findings from India’s Aircraft Accident Investigation Bureau (AAIB) suggest the crash may have been caused by accidental activation of fuel control switches, leading to simultaneous engine shutdown—rather than mechanical failure. Investigators have ruled out fuel contamination, flap misconfigurations, and structural faults.
Both black boxes (CVR and FDR) were recovered intact, confirming they delivered high-quality flight and voice data that authorities will soon publicly release.
Operational Fallout: Flights Delayed or Grounded
- The DGCA mandated enhanced inspections of Air India’s Boeing 787‑8/9 fleet starting June 15, focusing on engine systems, fuel controls, hydraulics, and throttles. Already, 26 out of 33 aircraft have been cleared; the rest are undergoing checks.
- In total, 66 Dreamliner flights were cancelled, contributing to an 83 wide-body flight cancelation count and a 15% reduction in long-haul operations through mid‑July. Routes including Ahmedabad–London, Delhi–Paris and Bengaluru–London were among the hardest hit.
- Additionally, Air India extended checks to its entire Boeing 777 fleet, aiming to maintain a reserve of serviceable wide-body aircraft during this disruption.
Oversight & Reforms: DGCA Steps In
- The DGCA has ordered Air India to strengthen coordination across engineering and operations teams and ensure spare parts availability to reduce disruption.
- Regulatory actions include removal of senior officials involved in crew scheduling and compliance lapses, and a show-cause notice for violating flight duty time limits. The DGCA also requested audit details from 2024–25 for deeper review.
Broader Implications & Status Update
- This tragedy marks the first fatal accident involving a Boeing 787 Dreamliner since it entered service in 2011.
- Air India officials have highlighted that the aircraft and both engines—overhauled in March and inspected in April—had a “clean maintenance history” and no issues were flagged before takeoff.
- A multi-disciplinary probe panel is expected to issue its final report within three months. Meanwhile, the preliminary findings will be published by July 11.
Summary
-
A likely human error involving fuel control switches appears to have led to dual engine shutdown during Flight AI 171.
-
India’s aviation regulator enforced fleet-wide safety checks, grounding flights, and reducing capacity on key routes.
-
Air India is under scrutiny for procedural and compliance gaps, while investigators work with black box data to pinpoint the exact error.
-
The airline’s ongoing flight disruptions and operational overhaul underline systemic reform needs for safety and oversight.
