The preliminary report on Air India's AI171 crash reveals that the fuel cut-off switches moved seconds after take-off without pilot input, leading to both engines shutting down.
The crash occurred 32 seconds after take-off, resulting in the loss of 241 of the 242 people on board and 19 people on the ground. One engine relit successfully, but the other did not recover, causing the crash just outside the airport perimeter.
A civil aviation analyst noted that the fuel control unit with the same part number as one highlighted in a 2018 FAA advisory for Boeing 737s was used in the Air India Boeing 787, raising concerns about the fuel control unit's functionality.
The investigation has reignited scrutiny over the FAA's 2018 warning regarding fuel control switch issues on Boeing aircraft, indicating potential similarities in the equipment used on the crashed Air India plane.
