Overview
- The Federation of Indian Pilots submitted a technical note to India’s aviation ministry and the AAIB urging independent electrical analysis and Boeing 787 simulator checks.
- A pre–lift-off electrical disturbance is the core hypothesis, with the group citing lithium‑ion battery short risks and abnormal voltage that could flip fuel‑shutoff relays without pilot input.
- The note explains that the 787 uses dual‑coil latching relays for fuel valves and that a reverse or erratic voltage could move both valves from RUN to CUTOFF at the same time.
- The pilots cite CCTV that they say shows the Ram Air Turbine deploying during the takeoff roll, an emergency power device whose early activation would point to an electrical problem before liftoff.
- Investigators’ preliminary report found both engines lost fuel before impact, media have floated pilot action, and the final report due next month will show if technical causes were fully tested for a crash that killed 260 near Ahmedabad on June 12, 2025.
