To my knowledge so:
Most important first, the pilot suffered injury to an arm and is going to do some surgery due to a shattered bone but is otherwise fine and there was no pax due to it being a maintenance flight.
The A/C had been reported having some problems with minor lock up in the hydraulics for the cyclic. The issue had been addressed once before but a couple of flights later the issue re-occurred. This time it was taken in for a more thorough inspection where to my knowledge to this date nothing was found.
The flight was a maintenance flight after above mentioned inspection and the heli suffered from the above mentioned problem once again this time to a larger effect causing more or less lock up of cyclic control and also affecting the collective.
The pilot started a descent and using the pedals for directional control to the best of his capabilities.
The lock up to my knowledge but I can be mistaken, happen in a 100ft HOGE for a engine check.
Aircraft impact was some 300ft/min
