Private pilot of a piper cherokee lance, PA32, had the landing gear collapse during landing, caused by loss of electrical power due to alternator belt missing. The reporter was aware of the missing belt prior to the last 2 flts with the intention of flying the aircraft to his maintenance shop. However, he did not perform the landing gear down check since he had left it down for the trip.

Narrative:
I flew back from new jersey to springfield, mo. The total flight time was 7 hours with a fuel stop in cincinnati. During the fuel stop I noticed the alternator belt was missing. I decided to continue the flight to springfield, mo, (3.5 hours) without the alternator. During the flight I conserved electrical power by turning off all non essential electrical equipment and used a hand held GPS for navigation. Eventually all power was lost and I had to extend the gear manually. The landing was successful. Maintenance is normally performed in bolivar, mo. I talked with the mechanic and he recommended charging the battery, leaving the gear in the down position and flying the plane to bolivar. I charged the battery for 3 days. I got in the airplane and started it. During the preflight check I noticed I did not have gear lights, but it did not concern me because the gear was down and I was taxiing on it. I took off from sgf and flew to bolivar. During the landing procedure, I performed the landing checklist but ignored anything to do with landing gear since I was not messing with gear. I still did not have green landing gear indicators. I landed softly and slowly but the gear was partially retracted (as observed by a witness). The gear up landing was uneventful. The airplane came to stop in the middle of the runway aligned with the runway.

Title: PVT PLT OF A PIPER CHEROKEE LANCE, PA32, HAD THE LNDG GEAR COLLAPSE DURING LNDG, CAUSED BY LOSS OF ELECTRICAL PWR DUE TO ALTERNATOR BELT MISSING. THE RPTR WAS AWARE OF THE MISSING BELT PRIOR TO THE LAST 2 FLTS WITH THE INTENTION OF FLYING THE ACFT TO HIS MAINT SHOP. HOWEVER, HE DID NOT PERFORM THE LNDG GEAR DOWN CHK SINCE HE HAD LEFT IT DOWN FOR THE TRIP.
Narrative: I FLEW BACK FROM NEW JERSEY TO SPRINGFIELD, MO. THE TOTAL FLT TIME WAS 7 HRS WITH A FUEL STOP IN CINCINNATI. DURING THE FUEL STOP I NOTICED THE ALTERNATOR BELT WAS MISSING. I DECIDED TO CONTINUE THE FLT TO SPRINGFIELD, MO, (3.5 HRS) WITHOUT THE ALTERNATOR. DURING THE FLT I CONSERVED ELECTRICAL PWR BY TURNING OFF ALL NON ESSENTIAL ELECTRICAL EQUIP AND USED A HAND HELD GPS FOR NAV. EVENTUALLY ALL PWR WAS LOST AND I HAD TO EXTEND THE GEAR MANUALLY. THE LNDG WAS SUCCESSFUL. MAINT IS NORMALLY PERFORMED IN BOLIVAR, MO. I TALKED WITH THE MECH AND HE RECOMMENDED CHARGING THE BATTERY, LEAVING THE GEAR IN THE DOWN POS AND FLYING THE PLANE TO BOLIVAR. I CHARGED THE BATTERY FOR 3 DAYS. I GOT IN THE AIRPLANE AND STARTED IT. DURING THE PREFLT CHK I NOTICED I DID NOT HAVE GEAR LIGHTS, BUT IT DID NOT CONCERN ME BECAUSE THE GEAR WAS DOWN AND I WAS TAXIING ON IT. I TOOK OFF FROM SGF AND FLEW TO BOLIVAR. DURING THE LNDG PROC, I PERFORMED THE LNDG CHKLIST BUT IGNORED ANYTHING TO DO WITH LNDG GEAR SINCE I WAS NOT MESSING WITH GEAR. I STILL DID NOT HAVE GREEN LNDG GEAR INDICATORS. I LANDED SOFTLY AND SLOWLY BUT THE GEAR WAS PARTIALLY RETRACTED (AS OBSERVED BY A WITNESS). THE GEAR UP LNDG WAS UNEVENTFUL. THE AIRPLANE CAME TO STOP IN THE MIDDLE OF THE RWY ALIGNED WITH THE RWY.
