Description is also consistent with 360 degree turn when pilot sees he
is too high- followed shortly by going from too high to too low
and then starting to force the turn, leading to stall or stall/spin.
Alternate speculation consistent with a common "stupid pilot trick".
FWIW- not much

If he did a full 360, does that mean he was already on final? Or could
he have done this on the base leg?

I've seen a pilot do a 270 at the base/final turn point. Obviously not
a good idea. Can't imagine someone doing a full 360 while on final.

i've seen it a few times. i did it myself. once. way early on before i
knew what the hell i was doing. everyone else who i've seen do it, or
talked to who did it, were also convinced it was probably not the best
idea. I think most of us had that realization somewhere around 200
degrees of turn I think...

Hi Gang
Don't you all think the 360 occurred in the spin to the ground? You
rarely if ever do a 360 on final or at least I don't.

I don't know if you saw Bruno's recent wheat field outlanding video.

http://www.youtube.com/watch?v=oJgSL4X6L-Y#t=10m55s

At the start point above, he's going to land in the green field just
past the ploughed one, right to left, towards the trees. He flies a
base (?) leg along the fence (the intended threshold), and then a
continuous right hand 270 onto short final.

Would be interesting to know if this was a power-on or power-off landing
and a soaring flight or were they motoring between airports. The
BLIPMAPS archives for that day may allow the possibility of a soaring
flight but I don't know how aggressive these guys would be in a
relatively low-glide performance touring mototglider. If the motoglider
has been under power it might be more unusual to keep the engine running
during landing but depends on their descent profile, it might have been
decided its just easier to shut down and descend.

I wonder if he ran out of gas? The report sounds like the flight was a
powered event. Did he get shook when the put-put quit? No logical
reason to do a 360 in the pattern, if you have excess
altitude..............just extend the down-wind a bit, unless you got
shook when the noise stopped. I guess the survivor can tell us. Sounds
like he didn't want to go any farther down-wind for fear he couldn't
get back without the motor?
Sad,
JJ
