THE PILOT NOTICED THAT THE GEAR UP INDICATOR LIGHT WAS NOT ILLUMINATED AND THAT THE GEAR WAS PARTIALLY EXTENDED. DURING THE SECOND ATTEMPT TO FULLY EXTEND THE GEAR, THE PILOT OBSERVED THE 'GREEN LIGHT' INDICATION IN THE COCKPIT; HOWEVER, THE PILOT THEN 'ELECTED TO CYCLE IT A COUPLE OF MORE TIMES' AND WITH THE GEAR RETRACTED CONTINUED THE FLIGHT. SUBSEQUENTLY, THE PILOT NOTED A REDUCED ELECTRICAL POWER OUTPUT AS THE RADIO LIGHTS HAD FADED IN INTENSITY AND THE AMMETER INDICATED A DISCHARGE. THE PILOT REPORTED REFERRING TO THE OPERATIONS MANUAL FOR EXTENSION OF THE LANDING GEAR; HOWEVER, 'DESPITE 60 TO 70 STROKES, THE GEAR WOULD NOT LOWER.' FOLLOWING THE LANDING, IT WAS DETERMINED THAT THE MAIN GEAR WERE PARTIALLY EXTENDED AND THE NOSE GEAR WAS FULLY EXTENDED WITH STRUCTURAL DAMAGE OCCURRING TO THE FUSELAGE. THE ALTERNATOR CIRCUIT BREAKER WAS 'POPPED' FOR AN UNDETERMINED REASON. FOLLOWING THE ACCIDENT, THE FAA INSPECTOR OBSERVED THE PILOT 'PUMP' THE EMERGENCY GEAR HANDLE 'IN AND OUT.' THE EMERGENCY CHECKLIST STATES PUMP 'PERPENDICULAR TO HANDLE.'
