The pilot said his tow aloft had been 'fairly rough,' and he released at 2,000 feet, in turbulence, and ascended in a thermal to 5,000 feet. He was 'frustrated' by the turbulence, and was 'having trouble controlling the plane,' so he decided to land. He began to get 'frustrated and nervous' and started 'breathing really hard because [he] was scared.' He began to 'feel strange,' and his face and hands 'felt numb. . .like they had fallen asleep.' He began to see 'a lot of little dots,' and he 'passed out.' He regained consciousness just before striking a stop sign. He flew under some powerlines, then landed in a field, and struck a pole embedded in the ground. A physician said the pilot was dehydrated and had hyperventilated, causing the brief lapse of consciousness.
Probable Cause: Pilot incapacitation (loss of consciousness) due to dehydration and hyperventilation. Factors were the turbulence and excessive workload (task overload) that induced anxiety/apprehension, and striking the sign and the pole.
