PRIOR TO ITS DIVERSION TO ANOTHER ARPT FOR INFLT PROBS; A B747-400 IS RELEASED FROM MAINT FACILITY WITHOUT THE CIRCUIT BREAKERS FOR THE HST WITHIN THE FMS BEING REACTIVATED AS REQUIRED BY THE SCHEDULED MAINT PROC AT ZZZ; US.

Narrative

I WAS ASSIGNED ACR TASK OF REACTIVATION OF THE HST SYS. AS I RECALL; I BEGAN BY REINSTALLING BOTH CANNON PLUGS IN THE WHEEL WELLS; WHERE I MOVED THE VALVE LEVERS TO MAKE SURE OF THE OP OF THE VALVE. I THEN MOVED TO THE WING FUEL PANEL. UPON OPENING IT; I FOUND 2 MEL STICKERS. AFTER CHKING THE LOGBOOKS; I REMOVED THE STICKERS AND WENT TO THE COCKPIT TO CHK FOR CIRCUIT BREAKERS AS STATED IN THE AMI-TASK. I FOUND NO CIRCUIT BREAKERS LABELED STABILIZER PUMP PULLED AND COLLARED. AS I READ THE PAPERWORK AGAIN; IT READ IN THE COCKPIT (P85) PANEL WITH NO QUOTATIONS AS TO THE EXACT CIRCUIT BREAKER'S NAME OR PANEL POS NUMBER. I THEN CHKED PANEL LABELS: THE P6 PANEL WAS LABELED; BUT THE CTR OVERHEAD PANELS WERE NOT LABELED. SO I RECHKED THE COCKPIT AND FOUND NO OTHER PANELS OR ANY CIRCUIT BREAKERS COLLARED OR PULLED. MOVING ON; I THEN FOUND NO MEL STICKERS ON THE FUEL MGMNT PANEL. I NOW BECAME CONCERNED WITH THE FACT THAT THERE WAS NO CHK-OUT IN THE PROC. AFTER FINDING MY LEAD; I REQUESTED HIM TO READ THE TASK AND CONFIRM THAT THERE WAS NO CHK-OUT; WHEN HE DID CONFIRM; AND HE HAD NO ADVICE AS TO HOW TO CHK THE SYS. I THEN REMOVED AND REPLACED THE PLACARDS ABOVE THE PFD'S AND MADE THE LOGBOOK ENTRIES. THESE FACTORS LED ME TO BELIEVE THAT CIRCUIT BREAKERS WERE NOT PULLED OR LABELED; AS I WOULD EXPECT THEM TO BE. FIRST; THE PAPERWORK STATED 'IN THE COCKPIT.' SECOND; SOME OF THE OVERHEAD PANELS WERE NOT LABELED IN THE COCKPIT; PLUS PREVIOUS EXPERIENCE HAD TAUGHT ME THAT CIRCUIT BREAKERS ARE NOT ALWAYS LABELED WHAT YOU WOULD EXPECT THEM TO BE; AND FINALLY NO MEL STICKERS ON THE FUEL MGMNT PANEL IN THE COCKPIT. I LATER FOUND THAT 10 DAYS PRIOR TO THIS INCIDENT; MAINT CTL HAD BEEN NOTIFIED AND NOTHING HAD BEEN DONE. THE PAPERWORK HAD BEEN WRITTEN INCORRECTLY; BECAUSE THE CIRCUIT BREAKERS WERE IN THE FLT ATTENDANT'S CREW COMPARTMENT AT THE TAIL OF THE PLANE AND THE CORRECT CIRCUIT BREAKER'S LABELS ARE 'HORIZ STAB XFER/JETT PUMP-RIGHT C3142' AND 'HORIZ STAB XFER/JETT PUMP-LEFT C3141;' NOT STABILIZER PUMPS.
