Narrative:

I was on the return leg of a round trip to gvw in kansas city, mo. My first approach was high and fast so I made a go around. My first decision was to leave the gear down. Then, because the airplane seemed slow and sluggish and because of incoming traffic, I decided to retract the gear to improve the performance. I entered the pattern and flew downwind, base and final. When I went through the landing checklist, I automatically thought 'the gear is down' and did not lower the gear. The landing was completed with the gear up. There was no personal injury. The landing gear warning system did not function. Subsequent investigation revealed a faulty switch in the circuit. Suggestions to prevent a recurrence: 1) insure that all warning and alarm system are working properly. 2) positively verify each checklist item.

Narrative: I WAS ON THE RETURN LEG OF A ROUND TRIP TO GVW IN KANSAS CITY, MO. MY FIRST APCH WAS HIGH AND FAST SO I MADE A GAR. MY FIRST DECISION WAS TO LEAVE THE GEAR DOWN. THEN, BECAUSE THE AIRPLANE SEEMED SLOW AND SLUGGISH AND BECAUSE OF INCOMING TFC, I DECIDED TO RETRACT THE GEAR TO IMPROVE THE PERFORMANCE. I ENTERED THE PATTERN AND FLEW DOWNWIND, BASE AND FINAL. WHEN I WENT THROUGH THE LNDG CHKLIST, I AUTOMATICALLY THOUGHT 'THE GEAR IS DOWN' AND DID NOT LOWER THE GEAR. THE LNDG WAS COMPLETED WITH THE GEAR UP. THERE WAS NO PERSONAL INJURY. THE LNDG GEAR WARNING SYS DID NOT FUNCTION. SUBSEQUENT INVESTIGATION REVEALED A FAULTY SWITCH IN THE CIRCUIT. SUGGESTIONS TO PREVENT A RECURRENCE: 1) INSURE THAT ALL WARNING AND ALARM SYS ARE WORKING PROPERLY. 2) POSITIVELY VERIFY EACH CHKLIST ITEM.
