Why did this helicopter crash ?

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.

Of course it's futile to 2nd guess the cause of this accident but its
obviously a mechanical malfunction and my guess its a hydraulic
failure. At first glance it appeared to be tail rotor failure but
given the gyrations, it is more than that. So, my best guess or WAG
(wild ass guess) is a near complete hydraulic failure with resultant
crazy control responses.
I must emphasize I only have 8000 hours in helicopters (13-14,000 in
fixed wing) and very little in the AStar so its only my best guess.

p.s. I'd like to see more on your website but as you know, its down? I
am a proponent on what you are doing for instructional purposes and
accident prevention. If you have another way to access your clips
please let me know?
