Video - Wright tumbles out of trampolining
Athens bronze medallist Huang Shanshan of China failed to qualify for the women's Olympic trampoline final after stumbling in her second routine.
Her compatriot He Wenna topped the standings with 67.20 ahead of world champion Russian Irina Karavaeva.
Athens gold and silver medallists, German Anna Dogonadze and Karen Cockburn of Canada also advanced.
Britain's Claire Wright missed out on a place in the final after finishing 10th on 63.10.
Huang was at a loss to explain her loss of balance in her routine which saw her stumble and land on her side.
"Of course I really feel extremely regretful," said the 21-year-old. "I still don't know what happened. I trained well and these things never happened before in training."
