Narrative:

Airport (unc) is a busy uncontrolled airport with 3 flight schools. Both r-hand and l-hand traffic was being used for runway 4. Because of the number of airplanes using the runway it was difficult to enter the pattern. After 3RD attempt (had to raise landing gear 3 times) I started on final. At 200 ft I lowered the landing gear and saw green indicator. I did not check the floor indicator. On touchdown it felt as if 1 gear folded and the aircraft started to turn, then the other main folded followed by the nose. Aircraft propeller contacted pavement. Minor damage to belly skin was observed. Mechanic examining the aircraft noticed that the gear circuit breaker had popped out.
