B767 CREW RAN CTR FUEL TANK DRY.

Narrative

FUEL IN CTR TANK. ON CLBOUT; CTR FUEL PUMP LIGHTS ILLUMINATED ON EICAS. I IMMEDIATELY CHKED THE CTR FUEL PUMPS AND THEY WERE IN FACT ON. ALL OF THE 1200 LBS OF FUEL THAT WAS IN THE CTR TANK HAD BEEN USED. I REMEMBER ONLY TURNING ON THE 4 MAIN TANK PUMPS. WHAT I THOUGHT I CHKED; BUT OBVIOUSLY DID NOT; WAS THAT THE CTR PUMPS WERE OFF. EVIDENTLY THEY WERE LEFT ON BY THE REFUELERS OR MAINT. I THINK THE CLICHE IS I SAW WHAT I WANTED TO SEE. DURING THE CHKLIST I SAW THAT WE HAD THE PROPER AMOUNT OF FUEL; THAT IT WAS BALANCED; AND WE HAD THE 1000 LBS REQUIRED FOR THE CTR TANK AND THE SWITCHES WERE IN THE PROPER POS. DURING THE JUST PRIOR TO ENG START CHKLIST; I TURNED ON ONLY THE 4 MAIN TANK FUEL PUMPS. ALMOST ALWAYS ALL FUEL BOOST SWITCHES ARE OFF -- IF NOT FROM THE PREVIOUS FLT -- YOU ENSURE THEY ARE OFF PRIOR TO OR DURING THE BEFORE STARTING CHKLIST. THIS ONE SLIPPED BY ME. BELIEVE ME; IT WILL NEVER HAPPEN AGAIN. SUPPLEMENTAL INFO FROM ACN 450761: WE INADVERTENTLY TURNED THE CTR TANK FUEL BOOST PUMPS ON FOR TKOF AND BURNED OFF THE 1000 LBS OF FUEL WHICH WAS SUPPOSED TO REMAIN UNUSED AS BALLAST FUEL PER BULLETIN ON THIS PARTICULAR MODEL OF B767.
