Narrative:

While doing touch and go's in an small aircraft, I believe that I had 3 in the green landing lights, but landed with no gear. No structural damage to wings, only propeller and bottom of airplane. Callback conversation with reporter revealed the following: student was landing the aircraft. The gear switch was in the down position and pilot's sure had 3 green lights. When aircraft jacked up and gear checked, it operated normally. This is electrically operated gear. FAA has investigated and classed as incident and pilot has heard nothing else from FAA, so doesn't know if violation being filed yet. Checklist for landing had been used.
