BE58 PLT LANDED WITH THE LNDG GEAR NOT SHOWING DOWN AND LOCKED. THE AUTO DIM FEATURE OF THE NAV LIGHTS PREVENTED DOWN AND LOCKED GREEN LIGHTS FROM BEING NOTICED.

Narrative

I ARRIVED AFTER XA30 ON MAR/TUE/03 FOR VFR FLT FROM LITTLE ROCK TO ZZZ. IT WAS MY PLAN TO BE IN ZZZ BTWN XB00 AND XB15 FOR BUSINESS. I STARTED THE ENGS AND; ACCORDING TO THE FAA DIRECTIVE ON COLLISION AVOIDANCE; I TURNED ON MY STROBE LIGHTS AFTER STARTING THE ENGS. I OBTAINED VFR CLRNC ON A CLR VFR DAY FOR VFR ARR TO STUTTGART. BEFORE TAXI; I TURNED ON THE NAV LIGHTS AND DEPARTED LITTLE ROCK IN THE RISING SUN. 10-15 MINS LATER; I ARRIVED AT STUTTGART AND MADE A NORMAL APCH. I LOWERED APCH FLAPS AND GEAR; REAFFIRMING THE GEAR HANDLE WAS DOWN. I NOTICED THE GEAR DOWN LIGHTS WERE NOT VISIBLE; BUT I KNEW FROM PAST EXPERIENCE THAT THE GEAR LIGHTS COULD NOT BE SEEN WITH THE NAV LIGHTS ON. I HAD NO REASON TO BELIEVE I HAD A PROB. I MADE AN APCH TO LNDG ON RWY 18 AT STUTTGART THINKING MY GEAR WAS DOWN. ON SHORT FINAL I CHKED THE GEAR HANDLE IN THE DOWN POS AND MADE A NORMAL LNDG FLAIR AND WAS SHOCKED WHEN I REALIZED THE GEAR HAD NOT FULLY EXTENDED. THE PLANE SKIDDED TO A STOP ON THE RWY. THE AIRPLANE WAS JACKED UP; AND THE GEAR COULD NOT BE EXTENDED IN A NORMAL FASHION; BUT DID EXTEND WITH THE EMER EXTENSION CRANK. THE GEAR MOTOR HAD MALFUNCTIONED. LNDG GEAR LIGHTS SHOULD BE OF ADEQUATE INTENSITY TO BE SEEN IN DAYLIGHT REGARDLESS OF NAV LIGHTS BEING ON. FAA MIGHT RECONSIDER ITS RECOMMENDATION TO TURN NAV LIGHTS ON PRIOR TO TAXI IN DAYLIGHT.
