The probe into the Air India plane crash is being led by the Aircraft Accident Investigation Bureau (AAIB). A London-bound Air India plane, AI171, crashed in Ahmedabad on June 12, killing 270 people.

Indian investigators of the deadly Air India airliner crash that killed 260 last month told a meeting of lawmakers that the plane's black boxes were not damaged, two people familiar with the discussions said.

Air India Flight 171's investigation zeroes in on pilot error after fuel switches were found turned off. With 260 lives lost, early findings suggest a devastating cockpit mistake may have caused the tragedy.
