The real cause of the helicopter crash which killed Leicester City owner Vichai Srivaddhanaprabha and four other passengers has been disclosed.
According to an Air Accident Investigation (AAIB) report, the cockpit pedals disconnected from the tail rotor leading to the crash.
The report stated that this caused the AW169 aircraft to turn uncontrollably to the right before it crashed near the King Power Stadium.
An inspection at the crash site found parts of a mechanism linking the pilot’s pedals to the tail rotor had become disconnected and there was a “build-up of black grease” on one component.
The failure of the system led to the pitch of the tail rotor blades being changed “until they reached the physical limit of their travel”.
The initiating cause and exact sequence of the failure that resulted in the loss of tail rotor control is being investigated as a priority.
However, the AAIB said its inquiries into the 27 October crash are still ongoing.
