Narrative:

Flying from atl to bna. Daytime VMC conditions, in a B727, on visual downwind for runway 20R. Fuel approximately 12000 pounds at the time. Problem: selecting flaps from 0 degrees to 2 degrees, we experienced an electrical malfunction (AC power malfunction). We tripped the #1 bus tie breaker, generator breaker and field relay. We also tripped the #2 bus tie breaker, generator breaker, and field relay. The #1 over voltage and the #2 under voltage lights were illuminated on the so's auxiliary panel. Checklists were accomplished in a rapid manner due to the amount of fuel remaining. Landing was normal. On taxi in, we had to use pneumatic brakes to stop the aircraft. (We did not have normal braking.) we had the aircraft towed in to the gate.

Title: B727 EXPERIENCES ELECTRICAL FAILURE AT BNA.

Narrative: FLYING FROM ATL TO BNA. DAYTIME VMC CONDITIONS, IN A B727, ON VISUAL DOWNWIND FOR RWY 20R. FUEL APPROX 12000 LBS AT THE TIME. PROB: SELECTING FLAPS FROM 0 DEGS TO 2 DEGS, WE EXPERIENCED AN ELECTRICAL MALFUNCTION (AC PWR MALFUNCTION). WE TRIPPED THE #1 BUS TIE BREAKER, GENERATOR BREAKER AND FIELD RELAY. WE ALSO TRIPPED THE #2 BUS TIE BREAKER, GENERATOR BREAKER, AND FIELD RELAY. THE #1 OVER VOLTAGE AND THE #2 UNDER VOLTAGE LIGHTS WERE ILLUMINATED ON THE SO'S AUX PANEL. CHKLISTS WERE ACCOMPLISHED IN A RAPID MANNER DUE TO THE AMOUNT OF FUEL REMAINING. LNDG WAS NORMAL. ON TAXI IN, WE HAD TO USE PNEUMATIC BRAKES TO STOP THE ACFT. (WE DID NOT HAVE NORMAL BRAKING.) WE HAD THE ACFT TOWED IN TO THE GATE.
