Fuel switch error caused India air crash
A preliminary report from Indian aviation accident investigators has revealed critical findings regarding the recent Air India crash in Ahmedabad, which resulted in the deaths of 260 individuals. The investigation indicates that the fuel switches for both engines of the Boeing 787 Dreamliner were shifted from "RUN" to "CUTOFF" just seconds after takeoff, leading to an immediate loss of thrust. This incident occurred shortly after the aircraft reached an altitude of 650 feet, ultimately crashing into a medical college hostel.
The Aircraft Accident Investigation Bureau (AAIB) is leading the inquiry, which is the deadliest aviation accident in a decade. Initial analyses of flight and voice data recorders, along with simulations of the aircraft's final moments, are focusing on the fuel control switches. Notably, cockpit recordings captured a conversation between the pilots, with one questioning why the fuel was cut off, while the other denied any action.
Despite the experienced crew, consisting of a captain with over 15,600 flight hours and a first officer with around 3,400 hours, the investigation has not identified any design or mechanical faults in the aircraft or engines. The AAIB has not issued any immediate directives for Boeing or General Electric, the engine manufacturer, and both companies are cooperating with the investigation.
The report suggests that the switches, which are designed with locking guards to prevent accidental movement, were likely manipulated intentionally. Investigators are now exploring whether the switch movements were deliberate, accidental, or due to a mechanical issue with the locking mechanism. This possibility had previously been highlighted in a 2018 FAA advisory that Air India had not acted upon.
The final report from the AAIB is anticipated within the year and will delve into various factors to provide a comprehensive understanding of the tragic incident.
