Narrative:

My daughter and I took a short ride in my 1979 F33A bonanza. Conditions were VFR and I obtained a WX briefing through the online service available at our local airport. I had not flown in several weeks and my plane was going in for its annual the next day. I did not file a flight plan due to the local nature of the flight. We flew for about 30 mins and returned to the airport. Upon entering the pattern; I did the usual preflight checks (gump; etc). I remember my daughter (who is 23) commenting on the drag the landing gear put on the plane. We both were convinced at that time that the landing gear was down. Upon landing; I felt a slight bump and then we hit the belly of the plane. As strange as it seems; the landing and subsequent slide was very uneventful. In fact; my daughter didn't even realize there was a problem until I told her to get out. The FBO and his mechanics had the plane jacked up; put on a dolly and removed from the runway in about 1 hour. There were no injuries of any kind. The engine oil temperature was hot in the pattern but I do not believe that was a big enough distraction to cause me to forget the gear. I am not sure what caused this problem; but it is obviously being looked at now.

Title: A B33A PLT LANDED GEAR UP WITH NO APPARENT DISTRS CAUSING A LAPSE IN CONCENTRATION.

Narrative: MY DAUGHTER AND I TOOK A SHORT RIDE IN MY 1979 F33A BONANZA. CONDITIONS WERE VFR AND I OBTAINED A WX BRIEFING THROUGH THE ONLINE SVC AVAILABLE AT OUR LCL ARPT. I HAD NOT FLOWN IN SEVERAL WKS AND MY PLANE WAS GOING IN FOR ITS ANNUAL THE NEXT DAY. I DID NOT FILE A FLT PLAN DUE TO THE LCL NATURE OF THE FLT. WE FLEW FOR ABOUT 30 MINS AND RETURNED TO THE ARPT. UPON ENTERING THE PATTERN; I DID THE USUAL PREFLT CHKS (GUMP; ETC). I REMEMBER MY DAUGHTER (WHO IS 23) COMMENTING ON THE DRAG THE LNDG GEAR PUT ON THE PLANE. WE BOTH WERE CONVINCED AT THAT TIME THAT THE LNDG GEAR WAS DOWN. UPON LNDG; I FELT A SLIGHT BUMP AND THEN WE HIT THE BELLY OF THE PLANE. AS STRANGE AS IT SEEMS; THE LNDG AND SUBSEQUENT SLIDE WAS VERY UNEVENTFUL. IN FACT; MY DAUGHTER DIDN'T EVEN REALIZE THERE WAS A PROB UNTIL I TOLD HER TO GET OUT. THE FBO AND HIS MECHS HAD THE PLANE JACKED UP; PUT ON A DOLLY AND REMOVED FROM THE RWY IN ABOUT 1 HR. THERE WERE NO INJURIES OF ANY KIND. THE ENG OIL TEMP WAS HOT IN THE PATTERN BUT I DO NOT BELIEVE THAT WAS A BIG ENOUGH DISTR TO CAUSE ME TO FORGET THE GEAR. I AM NOT SURE WHAT CAUSED THIS PROB; BUT IT IS OBVIOUSLY BEING LOOKED AT NOW.
