Incident Overview
A flight instructor was demonstrating a sod field landing to a student pilot. The approach and landing were conducted to the west with winds from the east at 7 knots. After touchdown, the instructor applied brakes for a full stop, but the airplane began to skid.
Sequence of Events
The instructor added power and configured the airplane for a go-around. He then attempted to abort the go-around because the flaps had not retracted, but the airplane again began to skid. During the skid, the flaps retracted, and he again applied power for takeoff. The instructor stated that he lacked sufficient runway to stop and could not gain adequate airspeed to fly. At the end of the runway, in an effort to clear a highway at the departure end, the pilot "popped" the airplane into the air. While over the highway, the airplane's landing gear struck the roof of a passing car. The airplane continued and landed in a field on the other side of the highway.
Post-Accident Examination
Examination of the airplane revealed no discrepancies with the flaps or the flap actuating system.
