The helicopter involved in a crash which killed the owner of Leicester City lost control after the pilot's pedals became disconnected from the tail rotor, investigators said.
This resulted in the aircraft making an uncontrollable right turn before it spun and crashed, according to a special bulletin by the AirAccidents Investigation Branch (AAIB).
The report revealed that a system linking the pilot's pedals with the tail rotor failed, according to the Telegraph.
An inspection at the crash site found parts of a mechanism 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", investigators noted.
The report stated: "The initiating cause and exact sequence of the failure that resulted in the loss of tail rotor control is being investigated as a priority."
Footage of the incident appears to show that sections of the tail rotor may have fallen off in mid-air.
