Former Aircraft Accident Investigation Bureau director stated that the preliminary findings into the Air India crash are not enough to determine the cause.
The Boeing 787-8 Dreamliner crashed 32 seconds after take-off from Ahmedabad, killing 241 on board and 19 on the ground.
The report presents a factual timeline but does not identify the trigger of the failure, with further technical analysis required.
The final report on the Air India crash is expected within 12 months, as the AAIB continues its investigation process.
