The helicopter crash which killed the chairman of Leicester Metropolis and 4 different folks on the 27th of October was attributable to a pin which had come unfastened within the tail rotor management mechanism, a report has revealed.

The Air Accidents Investigation Department discovered that the pin had turn into disconnected, ensuing within the helicopter turning into unstable and stopping the pilot from controlling it.
Investigators discovered the pilot’s pedals grew to become disconnected from the tail rotor and triggered the plane to make an uncontrollable proper flip earlier than it spun and fell, hitting the bottom in a ball of flames.
The pedals and tail rotor are linked by a mechanism which failed after elements of it had turn into disconnected and there was a “build-up of black grease” on one element.
The failure led to the pitch of the tail rotor blades being modified “until they reached the physical limit of their travel”, investigators mentioned.
The report said:
“The initiating cause and exact sequence of the failure that resulted in the loss of tail rotor control is being investigated as a priority.”
“The tail rotor actuator management shaft grew to become disconnected from the actuator lever mechanism.
“The disconnection stopped the suggestions mechanism for the tail rotor actuator from working and the tail rotor actuator from responding to yaw management inputs.”
This lack of the suggestions mechanism meant the yaw stops have been ineffective and the tail rotor actuator was capable of proceed altering the pitch of the tail rotor blades “until they reached the physical limit of their travel”.
