The Aircraft Accident Investigation Bureau (AAIB) has appointed veteran pilot and former Air India Director of Operations Captain RS Sandhu as a domain expert in the ongoing investigation into the deadly Air India plane crash in Ahmedabad last month, sources confirmed to the PTI on Sunday.

Sandhu, who was also a designated examiner for the Boeing 787-8 fleet at Air India, had taken delivery of the now-crashed 787-8 plane -- VT-ANB -- in 2013.

On June 12, Air India's Boeing 787-8 aircraft en route to London Gatwick from Ahmedabad crashed into a building soon after takeoff, killing 260 people, including 19 people on the ground. Out of the 242 people onboard, one passenger survived.
