## Analysis

DURING A NIGHT CROSS-COUNTRY FROM PRYOR, OK TO AVA, MO, THE AIRCRAFT EXPERIENCED A TOTAL ELECTRICAL FAILURE AS A RESULT OF A LOOSE ALTERNATOR BELT AND A DEPLETED BATTERY. ON ARRIVAL AT HIS DESTINATION, THE PILOT SELECTED GEAR DOWN WITH THE NORMAL EXTENSION HANDLE AND IMMEDIATELY LOST WHAT REMAINED OF HIS ELECTRICAL POWER. HE THEN EXTENDED THE GEAR USING THE EMERGENCY EXTENSION CRANK. ON TOUCHDOWN THE NOSE GEAR COLLAPSED AND FOLDED BACK INTO THE WHEEL WELL. EXAMINATION OF THE LANDING GEAR SYSTEM BY AN A&P MECHANIC REVEALED NO ABNORMALITIES IN EITHER THE NORMAL OR EMERGENCY EXTENSION SYSTEMS. HOWEVER, THE MECHANIC FOUND THAT THE ALTERNATOR BELT WAS LOOSE AND THE BATTERY WAS DEPLETED.
