Narrative:

I departed alliance, northeast, flying aeronautical commander 680. The WX was good and the flight to north platte, northeast, was uneventful. About 30 mi DME from north platte, I reported the lbf airport in sight and was cleared by ZDV for a visual approach to lbf. I acknowledged the clearance and began a gradual descent to a traffic pattern altitude of 4300 ft. ASOS reported the WX as clear below 12000 ft, winds 360 degrees at 8 KTS. Initially I planned for a left downwind entry for runway 30R because I like using the long runway whenever possible. I reported approximately 15 mi out for landing on CTAF frequency 123.0. I leveled off at my target altitude about 3 mi from the airport and allowed the aircraft to slow to about 120 KTS. As I approached the airport I saw that I was set up for a left base entry to runway 35. Although runway 35 is shorter, the wind was nearly down the middle, so I changed my plan and set up for runway 35. I reduced power, added flaps and reported turning a 1 mi final for runway 35 on CTAF. I intercepted final approach on the VASI GS and maintained the angle at 100 KTS and about 21 inches manifold pressure until flare and touchdown. I was not aware anything was wrong until I touched down on the belly of the aircraft with the gear up. I skidded straight ahead to a stop slightly right of centerline. I secured the engines and shut off all switches, except the master switch, strobes, beacon, and position lights, which I left on as I went for help, and to notify company headquarters.

Narrative: I DEPARTED ALLIANCE, NE, FLYING AERO COMMANDER 680. THE WX WAS GOOD AND THE FLT TO NORTH PLATTE, NE, WAS UNEVENTFUL. ABOUT 30 MI DME FROM NORTH PLATTE, I RPTED THE LBF ARPT IN SIGHT AND WAS CLRED BY ZDV FOR A VISUAL APCH TO LBF. I ACKNOWLEDGED THE CLRNC AND BEGAN A GRADUAL DSCNT TO A TFC PATTERN ALT OF 4300 FT. ASOS RPTED THE WX AS CLR BELOW 12000 FT, WINDS 360 DEGS AT 8 KTS. INITIALLY I PLANNED FOR A L DOWNWIND ENTRY FOR RWY 30R BECAUSE I LIKE USING THE LONG RWY WHENEVER POSSIBLE. I RPTED APPROX 15 MI OUT FOR LNDG ON CTAF FREQ 123.0. I LEVELED OFF AT MY TARGET ALT ABOUT 3 MI FROM THE ARPT AND ALLOWED THE ACFT TO SLOW TO ABOUT 120 KTS. AS I APCHED THE ARPT I SAW THAT I WAS SET UP FOR A L BASE ENTRY TO RWY 35. ALTHOUGH RWY 35 IS SHORTER, THE WIND WAS NEARLY DOWN THE MIDDLE, SO I CHANGED MY PLAN AND SET UP FOR RWY 35. I REDUCED PWR, ADDED FLAPS AND RPTED TURNING A 1 MI FINAL FOR RWY 35 ON CTAF. I INTERCEPTED FINAL APCH ON THE VASI GS AND MAINTAINED THE ANGLE AT 100 KTS AND ABOUT 21 INCHES MANIFOLD PRESSURE UNTIL FLARE AND TOUCHDOWN. I WAS NOT AWARE ANYTHING WAS WRONG UNTIL I TOUCHED DOWN ON THE BELLY OF THE ACFT WITH THE GEAR UP. I SKIDDED STRAIGHT AHEAD TO A STOP SLIGHTLY R OF CTRLINE. I SECURED THE ENGS AND SHUT OFF ALL SWITCHES, EXCEPT THE MASTER SWITCH, STROBES, BEACON, AND POS LIGHTS, WHICH I LEFT ON AS I WENT FOR HELP, AND TO NOTIFY COMPANY HEADQUARTERS.
