AFTER TAKING OFF IN INSTRUMENT CONDITIONS, THE PILOT SAW THE AIRPLANE'S CABIN LIGHTS FLICKER. SHORTLY THEREAFTER, THE LOW VOLTAGE WARNING LIGHT ILLUMINATED, AND THE VOLTMETER INDICATED AN ABNORMAL VOLTAGE READING. THE PILOT RECEIVED ATC CLEARANCE TO DEVIATE AND PERFORM AN ILS APPROACH TO A NEARBY AIRPORT. ON THE APPROACH, THE PILOT LOST THE LOCALIZER AND GLIDESLOPE INDICATIONS AFTER ATTEMPTING A NORMAL EXTENSION OF THE LANDING GEAR. THE INVESTIGATION DID NOT DETERMINE IF THE LANDING GEAR HAD GONE INTO THE DOWN AND LOCKED POSITION AT THIS TIME. A MISSED APPROACH WAS MADE AND THE PILOT RETURNED TO THE DEPARTURE AIRPORT WITH USE OF DEAD RECKONING. HE STATED THAT HE FOLLOWED THE EMERGENCY GEAR EXTENSION PROCEDURE, BUT WAS UNABLE TO VERIFY THAT THE GEAR WAS DOWN AND LOCKED DUE TO HIS HEAVY WORKLOAD AND ICE ACCUMULATION ON THE AIRPLANE. THE PILOT RECEIVED LIGHT GUN SIGNALS FROM THE TOWER TO LAND. WHILE LANDING, THE AIRPLANE'S LEFT GEAR COLLAPSED, THE AIRPLANE SKIDDED, STRUCK A MOUND OF DIRT AND A CONCRETE ELECTRICAL VAULT. POSTACCIDENT EXAMINATION REVEALED THE ALTERNATOR BELT HAD BECOME UNATTACHED. THE LANDING GEAR FUNCTIONED NORMALLY WHEN CHECKED AFTER THE ACCIDENT.
Probable Cause: A DISCONNECT OF THE ALTERNATOR BELT, AND FAILURE OF THE PILOT TO ATTAIN A DOWN AND LOCKED CONDITION OF THE GEAR WITH THE EMERGENCY EXTENSION SYSTEM.
