Authorities in India have been handed a preliminary report into the London-bound Air India flight that crashed last month, killing at least 260 people, but the public may not get to see its findings. The report, filed by the Indian government's Aircraft Accident Investigation Bureau (AAIB), is based on the initial findings of their investigation.

The investigation into June's deadly Air India crash reportedly centers on whether the fuel switches on the Boeing 787 Dreamliner functioned properly. The Aircraft Accident Investigation Bureau (AAIB) will release a preliminary report on Flight 171's crash on Friday,

The investigation into the Air India crash is also looking into the movement of fuel control switches that sit in the center console of the cockpit.
