July 12 (Reuters) - A preliminary report by Indian

aviation accident investigators said on Saturday the fatal Air

India crash that killed 260 people in Ahmedabad last month

showed the plane engines' fuel switches shifting from run to

cutoff within seconds of each other.

"At this stage of investigation, there are no recommended

actions to Boeing 787-8 and/or GE GEnx-1B engine

operators and manufacturers" India's Aircraft Accident

Investigation Bureau said.

The agency, an office under India's civil aviation

ministry, is leading the probe into the world's deadliest

aviation accident in a decade.
