Narrative

CALLED CLRNC AND GOT VFR CLRNC TO WACO; TX. TWR WAS ALSO WORKING GND. CALLED AND GOT TKOF CLRNC. WAS INSTRUCTED 'CLRED FOR TKOF; TURN L HDG 130 DEGS; MAINTAIN VISUAL SEPARATION WITH COMPANY TFC.' TOOK OFF AND RETRACTED GEAR; GEAR WOULDN'T RETRACT COMPLETELY (HIGH DRAG CONFIGN IN A T210) AND EXPERIENCED TOTAL ELECTRICAL FAILURE/LOST COM. MANUALLY CRANKED GEAR DOWN. WENT AHEAD AND SQUAWKED 7600; EVEN THOUGH I COULD SEE NO XPONDER REPLY LIGHT. FLEW LAST CLRNC AND EXITED LATERAL LIMIT OF CLASS C AIRSPACE; THEN DIRECT TO DEST. HIGH DRAW OF ELECTRICAL GEAR TOTALLY ZAPPED BATTERY. ELECTRIC ADI WITH NO BACKUP; ELECTRIC ALTIMETER HAD BACKUP. GOOD THING WX WAS NOT IMC. OVERFLEW DEST CLASS D ARPT (ACT) AT 3200 FT MSL LOOKING FOR GREEN LIGHT FROM TWR; STILL NORDO. NO PLANES/ACFT IN PATTERN. GND VEHICLE/PERSONNEL ON RWY 19 SVCING RWY LIGHTS; SO I MADE NORMAL LNDG ON RWY 14 AND TAXIED TO PARKING. NEVER GOT A GREEN LIGHT ON GEAR; SO I CHOSE THIS ARPT BECAUSE I KNEW IT HAD MAINT FACILITY AND EMER EQUIP. NEVER GOT A GREEN LIGHT FROM TWR; EITHER. I CALLED TO EXPLAIN SIT AND THEY DIDN'T EVEN KNOW I'D LANDED. CALLED AUSTIN; ALSO; AND EXPLAINED TO ATC WHY I NEVER CONTACTED DEP. ATC DID NOT SOLICIT EITHER TELEPHONE CALL. I WAS NEVER A CONFLICT TO MY KNOWLEDGE. EXPERIENCED DUAL ALTERNATOR FAILURE. IN THE FUTURE I WILL CARRY MY HAND- HELD COM RADIO AND CELL PHONE AS EMER COM BACKUP. ALSO I WILL NOT BECOME COMPLACENT ABOUT BEING DUAL ALTERNATOR EQUIPPED. BOTH FAILED IN THIS CASE; WITHOUT WARNING OR FAIL LIGHTS/LOW VOLTAGE LIGHTS.
