Narrative:

Flight normal up to the approach to the airport when aircraft small transport ahead was turning final for 26L, I was cleared a visual approach behind the small transport and was advised by tower to slow as I was overtaking small transport approximately 20 KTS. I complied and slowed to approximately 130 KTS, additionally squaring my base to final for additional separation. Prelndg checklist started when tower advised and I could see that small transport may not clear the runway before my landing, I added flaps 20 degree and slowed further to 110 KTS, as I believed I would have to go around as this is not unusual at atlanta hartsfield due to the type of high traffic airport. I was mentally prepared to go power up and go around at approximately the 100' point from the threshold end of the runway, instead the small transport did clear the runway approximately 2000' ahead of me and the tower cleared me to land after I asked for confirmation. Gear lever had been only in the halfway down position and was not fully down resulting in a gear up landing (there was no other traffic in the pattern or on the runway waiting takeoff (26R had been closed prior to my arrival)). As propeller tips began striking concrete runway it was too late to pull up and add power to determine gear in a positive down position. Only damage to the aircraft was propeller damage on all blades and scraping of the underbelly of approximately 5 linear feet of the aircraft no nose wheel damage inflicted. A proper rest period of 10 hours before the origination of the flight had been taken with the flight originating in orlando, fl, xa EST. Flight conditions along the route included initially moderate scattered to broken clouds at approximately 3500' for the first 20 mins then clear and at least 30 mi visibility throughout the remainder of the flight. There was no damage to any airport structure or any other object. No injury to any persons.

Title: GEAR UP LNDG.

Narrative: FLT NORMAL UP TO THE APCH TO THE ARPT WHEN ACFT SMT AHEAD WAS TURNING FINAL FOR 26L, I WAS CLRED A VISUAL APCH BEHIND THE SMT AND WAS ADVISED BY TWR TO SLOW AS I WAS OVERTAKING SMT APPROX 20 KTS. I COMPLIED AND SLOWED TO APPROX 130 KTS, ADDITIONALLY SQUARING MY BASE TO FINAL FOR ADDITIONAL SEPARATION. PRELNDG CHECKLIST STARTED WHEN TWR ADVISED AND I COULD SEE THAT SMT MAY NOT CLEAR THE RWY BEFORE MY LNDG, I ADDED FLAPS 20 DEG AND SLOWED FURTHER TO 110 KTS, AS I BELIEVED I WOULD HAVE TO GO AROUND AS THIS IS NOT UNUSUAL AT ATLANTA HARTSFIELD DUE TO THE TYPE OF HIGH TFC ARPT. I WAS MENTALLY PREPARED TO GO POWER UP AND GO AROUND AT APPROX THE 100' POINT FROM THE THRESHOLD END OF THE RWY, INSTEAD THE SMT DID CLEAR THE RWY APPROX 2000' AHEAD OF ME AND THE TWR CLRED ME TO LAND AFTER I ASKED FOR CONFIRMATION. GEAR LEVER HAD BEEN ONLY IN THE HALFWAY DOWN POSITION AND WAS NOT FULLY DOWN RESULTING IN A GEAR UP LNDG (THERE WAS NO OTHER TFC IN THE PATTERN OR ON THE RWY WAITING TKOF (26R HAD BEEN CLOSED PRIOR TO MY ARRIVAL)). AS PROPELLER TIPS BEGAN STRIKING CONCRETE RWY IT WAS TOO LATE TO PULL UP AND ADD POWER TO DETERMINE GEAR IN A POSITIVE DOWN POSITION. ONLY DAMAGE TO THE ACFT WAS PROPELLER DAMAGE ON ALL BLADES AND SCRAPING OF THE UNDERBELLY OF APPROX 5 LINEAR FEET OF THE ACFT NO NOSE WHEEL DAMAGE INFLICTED. A PROPER REST PERIOD OF 10 HRS BEFORE THE ORIGINATION OF THE FLT HAD BEEN TAKEN WITH THE FLT ORIGINATING IN ORLANDO, FL, XA EST. FLT CONDITIONS ALONG THE ROUTE INCLUDED INITIALLY MODERATE SCATTERED TO BROKEN CLOUDS AT APPROX 3500' FOR THE FIRST 20 MINS THEN CLEAR AND AT LEAST 30 MI VISIBILITY THROUGHOUT THE REMAINDER OF THE FLT. THERE WAS NO DAMAGE TO ANY ARPT STRUCTURE OR ANY OTHER OBJECT. NO INJURY TO ANY PERSONS.
