CHESTERFIELD, MO, USA
N2048Z
BEECH F33A
WHEN THE AIRCRAFT WAS RETURNING FOR LANDING, THE PILOT SELECTED GEAR DOWN AND STATED THAT HE FELT IT EXTEND BUT COULD NOT RECALL SEEING THE GREEN GEAR DOWN LIGHTS BECAUSE HE WAS SCANNING FOR TRAFFIC. SHORTLY AFTERWARDS HE EXPERIENCED A RAPID ELECTRICAL POWER DECAY. THE PILOT SATISFIED HIMSELF THAT THE GEAR WAS LOCKED DOWN BY USING THE EMERGENCY GEAR EXTENSION SYSTEM. AFTER RECEIVING A GREEN LIGHT FROM THE TOWER, THE PILOT LANDED ON THE MAIN GEAR AND EASED THE NOSE WHEEL ONTO THE RUNWAY. AS THE NOSE WHEEL TOUCHED THE RUNWAY THE NOSE GEAR COLLAPSED AND THE PROP AND NOSE OF THE AIRPLANE STRUCK THE RUNWAY. SUBSEQUENT INSPECTION REVEALED THAT ONE DIODE IN THE ALTERNATOR AND THE STORAGE BATTERY WERE INOPERATIVE, AND THE VOLTAGE REGULATOR WAS NOT OPERATING PROPERLY. THE NOSE GEAR EXTENSION BRACE WAS FOUND BENT ENOUGH TO PREVENT THE NOSE GEAR FROM EXTENDING COMPLETELY.
