PLT OF SMA PVT ACFT MADE A GEAR-UP LNDG AT AN UNCTLED ARPT AFTER AN UNSUCCESSFUL ATTEMPT TO EITHER EXTEND THE LNDG GEAR NORMALLY OR MANUALLY.

Narrative

CLRED FOR A VISUAL APCH TO STP RWY 32 I WAS IN R BASE LEG WHEN I SELECTED GEAR DOWN POS IN THE SMA ACFT. I WAS FLYING. AT THAT POINT I FAILED TO RECEIVE ANY GEAR DOWN LIGHTS. TOLD TWR I'D MAKE A R TURN AND GO E TO MANUALLY EXTEND THE GEAR. STP TWR ASKED IF I WANTED TO STAY ON MY IFR FLT PLAN WHICH I ELECTED TO CANCEL. I REMAINED AT 2000 FT MSL HDG 090 DEG TRYING TO MANUALLY EXTEND THE GEAR. AT THIS TIME THE MANUAL GEAR EXTENSION HANDLE MECHANISM BROKE WHICH LEFT ME WITH THE ABILITY TO TURN THE CRANK BUT THERE WAS NO EXTENSION OF THE GEAR. DURING THIS PHASE OF FLT WHILE REVIEWING THE EMER CHKLIST PROCS FOR FAILURE OF GEAR EXTENSION IT'S POSSIBLE THAT I ENTERED THE MSP TCA BUT I RATHER DOUBT IT. SHOULD A VIOLATION OF AIRSPACE HAVE OCCURRED IT'S BECAUSE IN A SINGLE PLT OP THE MAIN OBJECTIVE IN AN EMER IS TO FLY THE AIRPLANE; WORK ON THE EMER AND DON'T HIT THE GND. WHEN I REALIZED THAT I HAD A VERY SERIOUS PROBLEM; BEING THERE NOW WAS NO WAY TO GET THE GEAR EXTENDED; I ELECTED TO FLY TO EAU BECAUSE OF FOB MAINT EXPERTISE ON SMA ACFT. AT EAU I CIRCLED THE ARPT AT 3000 FT MSL DISCUSSED MY PROBLEM WITH FOB MAINT ON FREQ 123.0 AFTER AN HR TROUBLESHOOTING I ELECTED TO MAKE A GEAR UP LNDG ON RWY 32 EAU. CRASH RESCUE WAS CALLED I BRIEFED MY 3 PAXS; THE LNDG WAS MADE WITH MINIMAL DAMAGE TO THE ACFT. IN ALL HONESTY I DO NOT BELIEVE I VIOLATED ANY FAR'S BUT IN THE SITUATION I FOUND MYSELF BEING OCCUPIED WITH THE GEAR PROBLEM AND FLYING THE AIRPLANE IT'S POSSIBLE.
