Good Morning Skadi,
do you ever sleep. Everytime I want to post some news you've already done it .
Too bad to see that this master piece of helicopter science is not infallible.

That is a great pity, the only thing that I could translate in the article was the Euro 300K bit.
Good job it didn't hit the concrete or it would really have cost a bit.
A great photo of the turned inside out skid gear. Does it need stronger crosstubes and / or attach points or was it really tested beyond the proper drop test limit?
Nice to see that it is still upright.
Was it an auto practice perchance??????
cheers tet

Unofficially
Safety proven 
life is going on.... my order still stands
We are also so sorry for this accident. The crew called us this morning,
and the main point for us is that everybody is fine, and back to work
today. They told it was a pilot error, and admitted they were practicing
a risky failure simulation they were not trained for. And they are
already thinking to replace the Cabri by a new one.

ridiculously long words translated....
Helicopter crashed at Karlsruhe-Baden airport.
A helicopter crashed on the grounds at Karlsruhe-Baden airport on Monday afternoon, injuring the two occupants, fortunately only slightly.
According to initial findings from the police, the two men had begun a test flight within the airport area in a Guimbal G2 Cabri helicopter. For reasons yet unknown the aircraft fell from a height of from about two to three meters. The helicopter was severely damaged.
The first estimate of the damage amounts to about 300,000 Euros. The Federal Bureau of Aircraft Accidents Investigation in Braunschweig has been asked to investigate the cause of the accident.

Official information from Hélicoptères Guimbal :
Hello,
we confirm, alas! these very sad news.
However, it was partly exaggerated, as often : the two pilots are uninjured, and were back at work in perfect shape as soon as a few hours after the accident, when we spoke to them. At least some good news !
As far as we have heard from them, and this is definitely unofficial, they were practicing tail rotor failure when they lost the aircraft control, and stroke the ground at some significant speed - backwards.
They very honestly recognise a pilot error. They are very satisfied with the aircraft behaviour. Its fuselage and powerplant seem to be intact.
Both occupants had very low time on the Cabri type.
This aircraft had just, a few days before, joined its operational base in Germany, following a four month intensive evaluation period by all Eurocopter pilots, in France.
We have numerous and only excellent feedback from this operational evaluation, that was recently beeing concluded.
We only can repeat our message, initiated by the program's test pilot : " don't do anything with the Cabri that you wouldn't do with another light helicopter, and you'll enjoy a tremendous improvement in safety".
We all wish that this accident remains a bad baptism of fire. Fly safe!

Good news the drivers are ok, unfortunate for Bruno's new type but the cabin looks to have withstood the bingle pretty well. Interesting that they were going backwards at the time, maybe the practice emergency had been let develop too far but a reasonable outcome in real life. I would like to hear a bit more about the control authority of the fenestrom.

Bruno, your statement as quoted above says that your product was tested under operational conditions and was found "bad"ly at fault.
Hoping their insurance company doesn't cotton on to this!

Tail rotor failures
Mod: Not intended to blame pilots, quite the contrary, so mod you may remove my speculation.
I know from personal experience that the Motorflug guys are good in tail rotor failure training.
Tail rotor failures require quite some aero dynamic performance of the tail fin, depending on the settings of tail rotor power. It appears to me in the Cabri design that the effective surface is (in relative terms) smaller than say R44, B206. So we could have a sudden stall of the tail fin, combined with low inertia, that make the maneuver quite a bit more tricky.

Just becoming a bit confused here, but then I saw this really confusing bit.
Was it a practice T/R failure from the hover;
1) where the drivers started getting disorientated and then moving backwards before touchdown, or
2) was it simulated in forward flight and it developed into a T/R at hover after the forward A/S had washed off to come back to number 1, or
3) do they fly backwards and then simulate a T/R failure to drop to the ground before rotating into the forward A/S configuration?
In any of these events how can the quote above have significance when all airspeed is washed off, or nearly so?

Topendtorque
Perhaps along these lines....
Stuck tail rotor at 90% or 110% required for hover,
run on approach using side slip to cover for the fenestron performance gap and replacing it with tail fin power.
If well performed using even using a crosswind component, to avoid lateral motion during run on.
Sudden stall, making the heli spin...

Thanks D3 and understand, just up aways we saw; -
WRT the PFM what does it say about landing after a T/R drive failure in forward flight?
Hopefully there is nothing spooky in that prescribed procedure.
cheers tet

PFM
Don't know about the PFM, but at the current stage of experience (+- 10 ships) things may still need to be better understood at the limits of the envelop.
Personally I' am impressed with the body integrity, one of main design goals of Bruno, which appears to be achieved in real life imho.
