The helicopter in which the Leicester City owner died, Vichai Srivaddhanaprabha, crashed when the mechanism that joins the pedals of the cabin with the tail rotor was disconnected, according to a report published this Saturday by the British Air Accident Investigation Division.
That ruling caused the AW169 helicopter in which Srivaddhanaprabha and four other companions traveled to spin without control before crashing into the parking lot next to King Power Stadium on October 27.
In an inspection of the scene of the accident, investigators found part of the mechanism that had been disconnected and discovered that there was a “buildup of black fat” in one of its components. “The initial cause and the exact sequence of the failure that resulted in the loss of tail rotor control is being investigated as a priority,” the AAIB report states.
Footage of the aircraft’s last flight, taken from inside the ground, shows the AgustaWestland AW169 flying normally for about 40 seconds before it pauses and goes into a downward spin.
After the accident, the European Aviation Safety Agency (EASA) ordered the components of the AW169 helicopters and similar models to be revised.
The helicopter reached an altitude of approximately 430ft before crashing to the ground. It was engulfed in a post-impact fire and all five people on board were killed.
The European Aviation Safety Agency ordered safety checks to be carried out on the tail rotors of AW169s and similar models following the crash.
The five people who traveled in the device, that took off shortly after the match of the Premier league between Leicester and West Ham (1-1), died in the wreck.
Under the Thai’s leadership, Leicester achieved promotion to the Premier League for the 2015-2016 season. Widely expected to struggle on their return to the top-flight, the Foxes instead shocked the football world by winning the title.
