Maybe a hydraulic failure (lost the pressure) ?

Hi everybody,

This week I have uploaded a video of a helicopter crash on my website
(www.dappa.nl/crash.htm). Does anyone have a clue about the failure that
caused this crash? It is definately not an engine failure or a tail rotor
failure, but it still looks like a spectacular decend.

For the sensitive viewers: Nobody got hurt, but the helo is a complete
write
off.

Sorry for the multiple posts here. But on my first reply I meant to
say after he began the auto he had to pull collective when he neared
the buildings rooftops and he obviously didn't have any tail rotor
thrust to manage that collective pull. Notice how the heli yaws when
he arrests his descent. Read the initial NTSB reports.
