He was a passenger in a car we stopped and he never said a word, so he was released without charges.

A direction was given to remove the fore-aft bell crank ... and this was done.

The nose on the helicopter hit the ground at an angle slightly less than vertical.

Were you told ... there was any problem with the bell crank?

It should have remained joined but was apparently not joined and was broken away.

The helicopter then continued in a forward roll such that the helicopter then landed firstly on its roof and then on its port (left) side.

The bolt appears to have come out of the bell crank and the question is why that came out.

All was seemingly well until the last few seconds.

The air crew were performing their tasks diligently and in a controlled fashion.
