The Leicester City Football Club Helicopter Crash.

[BIAD]

For Sky's take on this...

'...The helicopter which crashed killing Leicester City's chairman and four others spun out of control after
a mechanism became disconnected, investigators said.

An Air Accident Investigation Branch (AAIB) report found cockpit pedals had disconnected from the tail rotor.
This caused the AW169 aircraft to turn uncontrollably to the right before it crashed near the King Power Stadium.
The AAIB said its inquiries into the 27 October crash were ongoing...'

'...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 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."...'

BBC:

'...The eight-page report, released today, said:

"The tail rotor system was first inspected at the crash site.
"This identified that the input lever mechanism was not attached to the control shaft.
"The pin, spacers and one of the locating bearings were missing from the lever.
"The locking nut and pin carrier were found loose in the tail rotor fairing and were bonded
together (they should be separate components)."...'
