Your glider may not always enter spin in the same direction you turn or circle. At high bank 50-60 degree in tight turn with high G load your upper wing may stall first. In a split second you can get in accelerated spin in unexpected direction. Scenario could be a new quick decision at altitude below 200 feet during land-out.
I witnessed Jantar Std3 doing 180 from downwind to short final in 60 degree of bank at an altitude about 150 feet. In the middle of RIGHT 180 turn the glider flipped LEFT and made ONE full turn of accelerated spin in about 2-3 seconds before hitting ground. UPPER (left) wing stalled first. It was so fast that there was no chance for pilot to react.


Could someone tell me what an "accelerated spin " is.
Thanks

"Accelerated spin" ? No such thing unless you wanted to quantify rotation rate.
I think what Marty and Andre meant to say was abrupt, unexpected departure.....
or departure from accelerated stall --
but that makes for less storydrama by having a more concise description.

Don't spin a Puch without chutes and a hard deck(1000m agl). Ever.

Best wishes,
