This is what I got from a Puma pilot who was there at the time;

It was a one-off prototype built to the French Army (ALAT) request for a Puma that could land, fold it’s blades and then taxy by wheeled power under cover, like a tree. It also had to be capable of crossing a 1 metre ditch. So it got a 1 metre+ ski between the nose wheels for the ditch crossing and the double bogies at the main gear. Apparently the blades were folded, I think with a freewheel system to allow an engine to keep operating, generating hydraulic power that powered the main wheels.

I remember Roland Coffignot (Test pilot) saying they built it, tested it, then spent a hour flying round the south of France trying to find a tree where the first (lowest) branches start 17 ft above the ground, not finding any and the programme was terminated. I suppose the airframe reverted back to a normal/standard aircraft.
