Narrative:
Conditions: bfm 300 ft scattered 800 ft overcast, mob 700 ft overcast. IFR flight plan jka to bfm with mob alternate. About 10 mi into a 27 mi flight, began losing electrical power. At 2000 ft, given vectors to bfm. Directed by mobile approach to fly outbound for VOR 14 approach to bfm. When reaching bfm for outbound leg, all power was lost. Advised unable to fly outbound as directed (flashlight had been dropped and was inoperative) as all panel lights were out. Directed to climb to 3000 ft (above clouds) and head north. Advised heading and altitude could not be seen and I'd do my best to comply. Unable to do ASR approach with mobile approach. Tried 'no gyro' approach with guidance from approach. Note: GPS-communication had battery backup -- communication and GPS signal maintained. Attempted turns as directed -- unable to complete left turns toward mob due to IMC. Passed north of mob then wbound as communication began to fail. Requests to approach to confirm heading from onboard GPS would not be confirmed from radar information. Lost communication. Decided to descend to altitude where ground reference could be maintained (500-700 ft AGL) and follow GPS direct track to mob (18 NM 106 degree radial). Entered airport environment and landed runway 14 without establishing communication for landing approvals. Taxied to ramp and advised safe landing. Approach advised search and rescue had been notified. Closed flight plan. Cause of electrical failure -- voltage regulator.

Title: A C210 COMMERCIAL PLT LOSES ALL ELECTRICAL PWR, GOES LOST COM AND USES GPS TO FIND THE ALTERNATE ARPT AT MOB, AL.
Narrative: CONDITIONS: BFM 300 FT SCATTERED 800 FT OVCST, MOB 700 FT OVCST. IFR FLT PLAN JKA TO BFM WITH MOB ALTERNATE. ABOUT 10 MI INTO A 27 MI FLT, BEGAN LOSING ELECTRICAL PWR. AT 2000 FT, GIVEN VECTORS TO BFM. DIRECTED BY MOBILE APCH TO FLY OUTBOUND FOR VOR 14 APCH TO BFM. WHEN REACHING BFM FOR OUTBOUND LEG, ALL PWR WAS LOST. ADVISED UNABLE TO FLY OUTBOUND AS DIRECTED (FLASHLIGHT HAD BEEN DROPPED AND WAS INOP) AS ALL PANEL LIGHTS WERE OUT. DIRECTED TO CLB TO 3000 FT (ABOVE CLOUDS) AND HEAD N. ADVISED HDG AND ALT COULD NOT BE SEEN AND I'D DO MY BEST TO COMPLY. UNABLE TO DO ASR APCH WITH MOBILE APCH. TRIED 'NO GYRO' APCH WITH GUIDANCE FROM APCH. NOTE: GPS-COM HAD BATTERY BACKUP -- COM AND GPS SIGNAL MAINTAINED. ATTEMPTED TURNS AS DIRECTED -- UNABLE TO COMPLETE L TURNS TOWARD MOB DUE TO IMC. PASSED N OF MOB THEN WBOUND AS COM BEGAN TO FAIL. REQUESTS TO APCH TO CONFIRM HDG FROM ONBOARD GPS WOULD NOT BE CONFIRMED FROM RADAR INFO. LOST COM. DECIDED TO DSND TO ALT WHERE GND REF COULD BE MAINTAINED (500-700 FT AGL) AND FOLLOW GPS DIRECT TRACK TO MOB (18 NM 106 DEG RADIAL). ENTERED ARPT ENVIRONMENT AND LANDED RWY 14 WITHOUT ESTABLISHING COM FOR LNDG APPROVALS. TAXIED TO RAMP AND ADVISED SAFE LNDG. APCH ADVISED SEARCH AND RESCUE HAD BEEN NOTIFIED. CLOSED FLT PLAN. CAUSE OF ELECTRICAL FAILURE -- VOLTAGE REGULATOR.
