Overview
- Investigators at India’s Aircraft Accident Investigation Bureau are preparing a more detailed interim report to be published before the June 12, 2026 anniversary because the full probe remains technically complex.
- The probe will focus on near‑simultaneous movement of the Dreamliner’s engine fuel switches that cut fuel to both engines and on cockpit voice recordings that raised the possibility of pilot action.
- India’s aviation regulator plans to observe Boeing tests of the fuel‑switch mechanism in Seattle after pilots reported irregular switch behaviour on a February 2026 Air India Dreamliner flight.
- Boeing is participating as a technical adviser while the AAIB must follow ICAO consultation rules that allow the NTSB and other states to review and comment on any final report.
- Families of the 260 victims may wait longer for closure because the interim statement leaves open final attribution and could lead to safety directives, design changes, or new operating procedures depending on test results.
