AN S80 PIC STARTS HIS L ENG PREMATURELY WITHOUT BENEFIT OF GND CREW COM.

Narrative

AFTER A 30 MIN DELAY AT THE GATE FOR MAINT; WE WERE NOW READY FOR DEP AND WE CALLED RAMP TWR TO NOTIFY OUR GND PERSONNEL TO COME TO THE ACFT. AS THE JETBRIDGE HOOD WAS BEING RETRACTED; THE RAMP PERSONNEL LOOKED OUT OF THEIR SHACK; BUT THEN WENT BACK INSIDE. AFTER THE BRIDGE WAS PULLED; WE STILL WAITED SEVERAL MORE MINS FOR RAMP PERSONNEL; WHO FINALLY TRICKLED OUT TO THE ACFT AT A SNAIL'S PACE. I EVENTUALLY OBSERVED A GND MAN BY OUR GND INTERPHONE PANEL WITH HIS GOGGLES AND WANDS; AS HE PULLED OUR GND ELECTRIC. AS I OBSERVED HIS ACTIONS; I THOUGHT THAT HE WAS ABOUT TO CALL US FOR ENG START. SO; TO HELP EXPEDITE THIS NEEDLESS DELAY SIT; I BEGAN TO TURN THE L ENG IN ANTICIPATION OF HIS CALL ON THE INTERPHONE. HOWEVER; AS THE L ENG WAS STARTING; HE DID NOT CALL ON THE INTERPHONE AS I HAD EXPECTED. SINCE I KNEW THAT THE L SIDE OF THE ACFT WAS CLR; AND WE HAVE HIGH TAIL MOUNTED ENGS; I LET THE L ENG IDLE. SOON THEREAFTER; THE GND MAN CONTACTED US ON THE INTERPHONE. I THEN TRIED TO CLR UP THE CONFUSION ABOUT THE ENG START AND GOT CLRNC TO START THE R ENG. THE R ENG START AND PWRBACK THEN PROCEEDED NORMALLY. I APOLOGIZE FOR THIS MISTAKE AND JUMPING THE GUN. IN THE FUTURE; I WILL ABSOLUTELY NOT TURN THE ENG UNTIL IN DEFINITE CONTACT WITH THE GUIDE MAN; REGARDLESS OF THE FRUSTRATING AND SEEMINGLY NEEDLESS DELAYS BEING TAKEN.
