What caused the Air India Flight AI-171 crash?
The crash is believed to be linked to the movement of engine fuel control switches, which were found flipped to 'CUTOFF' shortly after takeoff. Investigators are analyzing flight data and simulations to determine if this switch movement caused the engine failure that led to the crash. The investigation is also considering other factors like system faults or human error.

How do engine fuel control switches work in aircraft?
Engine fuel control switches regulate the flow of fuel to the aircraft's engines. They are designed to prevent accidental activation and typically have safety features like locking mechanisms. In this case, the switches' movement to 'CUTOFF' was immediate after takeoff, which is unusual and is now a key focus of the investigation.
-
What are investigators focusing on in this case?
Investigators are primarily examining the role of the fuel control switches, analyzing flight data, and running simulations to understand if the switches' movement was accidental or caused by a mechanical or procedural fault. They are also reviewing past safety advisories related to these switches and their design.
-
Could this incident happen again?
While investigations are ongoing, experts are looking into the safety features of fuel control switches and aircraft systems to prevent similar incidents. Improvements in design, better training, and stricter safety protocols could help reduce the risk of a repeat, but the final conclusions depend on the investigation's findings.
-
What is the significance of the preliminary report?
The preliminary report will provide initial insights into what caused the crash, especially regarding the fuel switches. It will help airlines, manufacturers, and regulators understand potential safety issues and implement measures to prevent future accidents.
-
Are there past incidents related to fuel switch malfunctions?
Yes, past advisories from the FAA and other aviation authorities have highlighted potential issues with fuel switch locking mechanisms. These incidents underscore the importance of system integrity and proper maintenance to ensure safety in commercial aviation.
