Narrative:

I was in traffic pattern having completed 2 previous touch- and-goes. This was to be a complete stop. While on downwind after lowering 15 degrees of flaps but prior to lowering of gear, another aircraft was heard on the radio in the traffic pattern. I stopped the checklist to acquire the aircraft visually. For unknown reasons, I did not go back and finish checklist. On very short final I noticed full flaps but no green lights on gear. I applied full power for go around at this time. I had an uneventful go around and completed the landing. An inspection of the aircraft revealed minor damage. I cannot explain how this happened other than the checklist was broken and not completed. I have instituted a second short final check of flaps and gear to try and prevent this from happening in the future.

Title: SMT MAKES GAR WHEN NO GREEN LIGHTS SHOW ON LNDG.

Narrative: I WAS IN TFC PATTERN HAVING COMPLETED 2 PREVIOUS TOUCH- AND-GOES. THIS WAS TO BE A COMPLETE STOP. WHILE ON DOWNWIND AFTER LOWERING 15 DEGS OF FLAPS BUT PRIOR TO LOWERING OF GEAR, ANOTHER ACFT WAS HEARD ON THE RADIO IN THE TFC PATTERN. I STOPPED THE CHKLIST TO ACQUIRE THE ACFT VISUALLY. FOR UNKNOWN REASONS, I DID NOT GO BACK AND FINISH CHKLIST. ON VERY SHORT FINAL I NOTICED FULL FLAPS BUT NO GREEN LIGHTS ON GEAR. I APPLIED FULL PWR FOR GAR AT THIS TIME. I HAD AN UNEVENTFUL GAR AND COMPLETED THE LNDG. AN INSPECTION OF THE ACFT REVEALED MINOR DAMAGE. I CANNOT EXPLAIN HOW THIS HAPPENED OTHER THAN THE CHKLIST WAS BROKEN AND NOT COMPLETED. I HAVE INSTITUTED A SECOND SHORT FINAL CHK OF FLAPS AND GEAR TO TRY AND PREVENT THIS FROM HAPPENING IN THE FUTURE.
