AS350 slips/spins on helipad
Hi,
Does anyone have a link to the video of the AS350 slipping/spinning on the helipad in Italy on the 27.07.2009
Thanks.

Yeah.. doesn't look like the best time to be standing out there. The main rotor blades are doing quite a dance too.
The details from the video:
I-LVNA on the island of Ischia.

The PIC continues to lean across the panel even after the machine starts its 360?!
Also, the disk seems to be at max pitch at 10 o'clock so the reporter was fortunate to have run backwards - if he'd run forwards, I think he may have lost his loaf

Anyone any ideas as to what might have caused this? Momentary lapse in attention, Not frictioning the collective enough allowing it to come up on its own? Maybe made worse by slamming the collective down and thus reducing the torque to a minimum while already too much right pedal in(power pedal due to clockwise rotation).
Just trying to figure it out, so it doesn't happen to me someday.

Looks like a couple of things contributed to this near accident.
It rotated against the torque reaction off the main rotor so it must have had a lot of right pedal in. Perhaps the pilot did this inadvertently whilst leaning over the console to help his passenger strap in.
The Squirrel has a clip on the bulkhead and a corresponding metal "pip" on the lever to hold down the collective. If this isn't engaged, the collective rises as the hydraulics come on line during the start sequence and the aircraft goes light on the skids all by itself. I used to put my knee across the collective to make doubly sure this "gotcha" didn't "get me".

At flight rpm one day (col friction on) just prior to t/off I was distracted by something a pax was doing behind me that needed my full attention, I was leaning around to the right as far as pos whilst waving my right arm frantically (AS350 right hand doors off on a fuel soaked timber pad) the chopper yawed about 30" and nearly off the pad, I hadn't realized in turning to the right I had used pressure on my right foot to do so.
Traps for the young and foolish not so, if your not looking up its hard to tell what the movement your feeling is, and if its sudden and unexpected what to do about it

one thing is for sure, that chewing gym got a fair work out after it stopped spinning!
IMHO the pilot was trying to correct something that had gone wrong on the center consol, whether the co pilot/passenger had done some thing is very possible, as its stops when he, foolishly, gets out.
still would have shut it down and gone for a cuppa at least before even thinking of going up in her again!

The speedy chewing of gum says speaks volumes - and the look on his face says, (loose translation), " Oh sh!t - there's a camera! I'll be all over YouTube and Pprune by tomorrow! Perhaps if I fly back now, I can drop the aircraft off and be away home before the boss sees it!.

Regarding the discussion about the collective coming up by itself. Would it not be safe to assume that in this case the collective was all the way down ? If it were up, wouldn't the helicopter rollover, especially with that much cyclic directed to the one side ?
