BE40 SUFFERS LOSS OF R MAIN AC BUS. RETURNED TO DEP ARPT FOR ZERO FLAP; NO THRUST REVERSER; NO SPOILER LNDG. HEAT FROM MANUAL BRAKING RESULTS IN BLOWN TIRES ON TAXI IN.

Narrative

UPON CLB FROM FL270 TO FL320 THE R GENERATOR FAILED. I TRIED ONE RESET AND IT WOULD NOT COME BACK ON LINE. I THEN TURNED TO MY L TO CHK CIRCUIT BREAKERS WHEN MY COPLT ADVISED THE R GENERATOR CAME BACK ON LINE; WE WERE STILL CLBING WHEN I OBSERVED THE GENERATOR AMP LOAD METER ON THE R GENERATOR DROP TO 100 AMPS THEN FALL TO 0 AMPS. A FEW SECONDS LATER THE ENTIRE R MAIN BUS FAILED AND THE COPLT LOST ALL EFIS AND FMS UNITS. THE AUTOPLT KICKED OFF. I ADVISED THE COPLT 'I'VE GOT THE PLANE.' I TOLD THE COPLT TO ADVISE ZTL WE HAD AN ELECTRIC FAILURE AND NEEDED TO RETURN TO CHARLOTTE. WE REVERSED COURSE AND STARTED OUR DSCNT FOR CHARLOTTE; AFTER RUNNING THE GENERATOR FAILURE; ELECTRIC BUS FAILURE CHKLISTS WE THEN RAN THE 'ZERO FLAP' LNDG AND EMER LNDG GEAR EXTENSION CHKLIST. WE THEN CHKED OUR ACFT LNDG WT AND FOUND WE WERE WELL UNDER THE 15500 MAX LNDG WT AT 15100 LBS WITH A NO FLAP LNDG REF SPD OF 143 KTS. THE COPLT AND I DETERMINED THE LNDG DISTANCE REQUIRED WOULD BE APPROX 6850 FT BASED ON NO FLAPS; NO SPD BRAKES; NO THRUST REVERSERS. WE WERE CLRED TO LAND ON RWY 36R AT CLT WHICH IS 8674 FT. WE TOUCHED DOWN ON THE NUMBERS OF RWY 36R AND ROLLED WITH MANUAL BRAKE PRESSURE TO A STOP WITHOUT INCIDENT WITH APPROX 1900 FT OF RWY LEFT. AFTER CLRING THE RWY WE WERE CLRED TO TAXI ACROSS RWY 36R TO THE RAMP. WE HAD TO COME TO A COMPLETE STOP TO GIVE WAY TO AN ACFT PASSING IN FRONT OF US ON THE TXWY AFTER CLRING THE OTHER ACFT BOTH MAIN GEAR TIRES THERMALED DUE TO THE EXCESSIVE HEAT FROM THE BRAKES. WE WERE CLR OF THE ACTIVE RWY SO ARPT OPS WERE NOT INTERRUPTED. THE PLANE WAS THEN TURNED TO THE FBO RAMP WHERE REPAIRS COULD BE MADE; AND OUR 2 PAX COULD GET A CHARTER FLT BACK HOME. THERE WAS NO DAMAGE TO THE ACFT; SAVE THE TIRES AND BRAKES.
