Narrative:

After landing in shv, while taxiing to the gate, first officer attempted to start the APU. The aircraft lost total electrical power and veered hard left and came to a stop with the nose wheel and main gear in the grass. No injuries or damage to aircraft. Nose wheel steering and rudder pedal control of the emb 120 is electrical, without electric we had no control. This same problem has occurred on other emb 120's, but it is rare. The only way I can see to keep this from happening again, is to only start the APU with the aircraft stationary.

Original NASA ASRS Text

Title: TOTAL ELECTRICAL PWR LOSS ON THE GND.

Narrative: AFTER LNDG IN SHV, WHILE TAXIING TO THE GATE, FO ATTEMPTED TO START THE APU. THE ACFT LOST TOTAL ELECTRICAL PWR AND VEERED HARD L AND CAME TO A STOP WITH THE NOSE WHEEL AND MAIN GEAR IN THE GRASS. NO INJURIES OR DAMAGE TO ACFT. NOSE WHEEL STEERING AND RUDDER PEDAL CTL OF THE EMB 120 IS ELECTRICAL, WITHOUT ELECTRIC WE HAD NO CTL. THIS SAME PROB HAS OCCURRED ON OTHER EMB 120'S, BUT IT IS RARE. THE ONLY WAY I CAN SEE TO KEEP THIS FROM HAPPENING AGAIN, IS TO ONLY START THE APU WITH THE ACFT STATIONARY.
