Following the Aircraft Accident Investigation Bureau’s (AAIB) preliminary report into the recent fatal Air India plane crash, airlines have begun inspecting the locking mechanism of fuel switches on Boeing 787 aircraft, reported the IANS.

According to the news agency, the initial findings, based on the crash of an Air India Dreamliner in Ahmedabad, indicate that fuel supply to both engines was abruptly cut off shortly after take-off, resulting in the tragic accident. Experts have raised concerns that a malfunction in the locking feature of the fuel control switches may have been a contributing factor.

The AAIB report noted that there is currently no “recommended action” for Boeing, the aircraft manufacturer, or General Electric (GE), which produced the engines.
