AN SMT PLT ADMITS THAT HE STARTED TO TAXI BEFORE THE EXTERNAL PWR WAS REMOVED FROM THE ACFT.

Narrative

I COMPLETED THE WT AND BAL FORM; THEN HANDED IT TO THE RAMP AGENT. I SIGNALED TO HIM THAT I WAS READY TO START THE #2 ENG. THE #2 ENG STARTED WITHOUT PROBS. I THEN SIGNALED TO START THE #1 ENG. JUST BEFORE SELECTING THE #1 FUEL LEVER ON; THE RAMP AGENT INDICATED TO STOP THE SEQUENCE. AFTER RELEASING THE START SELECT SWITCH; I TURNED TOWARDS THE #1 ENG TO SEE IF ANYTHING WAS WRONG. AS I TURNED; ANOTHER RAMP AGENT ARRIVED WITH AN ADDITIONAL LOAD OF BAGS. SINCE THE #2 ENG HAD ALREADY BEEN STARTED; I SWITCHED FROM EXTERNAL PWR TO ACFT BATTERY PWR. THE #2 ENG RPM WAS INCREASED TO 66%; THEN THE #2 GENERATOR WAS PUT ON-LINE. I LOOKED UP TOWARDS THE FRONT OF THE ACFT TO SIGNAL THAT THE EXTERNAL PWR COULD NOW BE DISCONNECTED; BUT THE RAMP AGENT WAS ASSISTING WITH THE LOADING OF THE ADDITIONAL BAGS. I THEN STUCK MY HEAD OUT THE WINDOW INTENDING TO TELL THEM TO DISCONNECT THE EXTERNAL PWR; BUT INSTEAD BECAME DISTR WHEN GIVEN THE WT OF THE ADDITIONAL BAGS. I CORRECTED BOTH COPIES OF THE WT AND BAL FORM AND GAVE THE AGENT THE STATION'S COPY. I SIGNALED THAT I WAS READY TO START THE #1 ENG. ENG #1 WAS STARTED; AND I SIGNALED TO THE RAMP AGENT WITH A THUMBS UP THAT I WAS READY TO TAXI. I AM NOT SURE; BUT BELIEVE HE RETURNED WITH A THUMBS UP. I LOOKED TO THE R FOR TFC AND PROCEEDED TO TURN R. AS THE ACFT TURNED; THE FO TOLD ME TO STOP BECAUSE THE RAMP AGENT HELD HIS FIST UP. I STOPPED THE ACFT AFTER TURNING APPROX 2-3 FT TO THE R. THE EXTERNAL PWR UNIT'S PLUG HAD CAUGHT THE PINS ON THE ACFT'S RECEPTACLE TO BEND SLIGHTLY AFT REQUIRING REPLACEMENT. POSSIBLE CONTRIBUTING FACTORS: DEC/THU/96 WAS MY SIXTH STRAIGHT DAY OF WORK IN A ROW. I FELT A LITTLE TIRED BUT OTHERWISE FINE. I BECAME A BIT IRATE THAT THE FLT WAS TO BE DELAYED FURTHER WHEN THE ADDITIONAL BAGS WERE PLACED ON THE ACFT. BY PLACING THE #2 GENERATOR ON-LINE AND HAVING THE EXTERNAL PWR DISCONNECTED WHILE THE RAMP AGENTS WERE LOADING THE BAGS; I WAS TRYING TO DECREASE THE DELAY. UNFORTUNATELY MY ATTN SHIFTED TO QUICKLY COMPLETING THE CORRECTED WT AND BAL FORM.
