Narrative:

My attention was distracted by the preceding aircraft, an small aircraft, reporting, 'downwind, stop and go.' I entered the traffic behind him, and requested if he was going to make a 'touch and go.' his reply was 'no, I am going to make a 'stop and go.' we discussed what a stop and go might be and, as we entered the pattern, I applied 'takeoff' flaps. My plane being faster, I slowed to final approach speed, and widened out the base leg to provide more spacing. This required more power than usual to fly the pattern, and my attention was focused on the small aircraft to see if he would be clear of the runway for my landing. I was in the slot, carrying more power than usual because of the unusually large pattern. There was no gear warning, as I carried power to touchdown, as is common in this aircraft. I landed gear up on the runway. Damage to the plane was minimal for a gear up landing. The propeller was damaged, the engine suffered sudden stoppage, 3 antennas on the belly were destroyed, and about 3 ft of belly skin was scraped off from forward to aft. The best of my knowledge, that is the extent of the damage. I allowed my attention to the inside of the cockpit to be distracted by the unusual situation, and the unclr intentions first officer the preceding aircraft. It is very possible that complacency, as well as familiarity added a part to this occurrence. The FAA investigator on the scene said this will be classified as an 'incident.' the 3 passenger were all licensed pilots, and no one realized that the gear was not down. In fact, my first reaction to the situation was that, for some reason, the nose gear had collapsed.

Title: PLT OF AN SMA SINGLE ENG LAND ACFT INADVERTENTLY FORGOT TO LOWER THE LNDG GEAR AND LANDED GEAR-UP.

Narrative: MY ATTN WAS DISTRACTED BY THE PRECEDING ACFT, AN SMA, RPTING, 'DOWNWIND, STOP AND GO.' I ENTERED THE TFC BEHIND HIM, AND REQUESTED IF HE WAS GOING TO MAKE A 'TOUCH AND GO.' HIS REPLY WAS 'NO, I AM GOING TO MAKE A 'STOP AND GO.' WE DISCUSSED WHAT A STOP AND GO MIGHT BE AND, AS WE ENTERED THE PATTERN, I APPLIED 'TKOF' FLAPS. MY PLANE BEING FASTER, I SLOWED TO FINAL APCH SPD, AND WIDENED OUT THE BASE LEG TO PROVIDE MORE SPACING. THIS REQUIRED MORE PWR THAN USUAL TO FLY THE PATTERN, AND MY ATTN WAS FOCUSED ON THE SMA TO SEE IF HE WOULD BE CLR OF THE RWY FOR MY LNDG. I WAS IN THE SLOT, CARRYING MORE PWR THAN USUAL BECAUSE OF THE UNUSUALLY LARGE PATTERN. THERE WAS NO GEAR WARNING, AS I CARRIED PWR TO TOUCHDOWN, AS IS COMMON IN THIS ACFT. I LANDED GEAR UP ON THE RWY. DAMAGE TO THE PLANE WAS MINIMAL FOR A GEAR UP LNDG. THE PROP WAS DAMAGED, THE ENG SUFFERED SUDDEN STOPPAGE, 3 ANTENNAS ON THE BELLY WERE DESTROYED, AND ABOUT 3 FT OF BELLY SKIN WAS SCRAPED OFF FROM FORWARD TO AFT. THE BEST OF MY KNOWLEDGE, THAT IS THE EXTENT OF THE DAMAGE. I ALLOWED MY ATTN TO THE INSIDE OF THE COCKPIT TO BE DISTRACTED BY THE UNUSUAL SIT, AND THE UNCLR INTENTIONS FO THE PRECEDING ACFT. IT IS VERY POSSIBLE THAT COMPLACENCY, AS WELL AS FAMILIARITY ADDED A PART TO THIS OCCURRENCE. THE FAA INVESTIGATOR ON THE SCENE SAID THIS WILL BE CLASSIFIED AS AN 'INCIDENT.' THE 3 PAX WERE ALL LICENSED PLTS, AND NO ONE REALIZED THAT THE GEAR WAS NOT DOWN. IN FACT, MY FIRST REACTION TO THE SIT WAS THAT, FOR SOME REASON, THE NOSE GEAR HAD COLLAPSED.
