B737-200 CREW HAD THE #1 ENG THROTTLE BECOME DISCONNECTED AFTER A DOUBLE ENG CHANGE.

Narrative

ACFT AXXB WAS IN THE PROCESS OF A DUAL ENG CHANGE. THE CREW I WORK ON HAD HUNG THE #1 ENG AND ACCOMPLISHED A FEW OF THE SYS HOOK-UPS. 2 OTHER MECHS ACCOMPLISHED THE CONNECTION AND RIGGING ADJUSTMENTS OF THE THROTTLE AND FUEL CUTOFF LINKAGES. I ASKED ONE OF THE MECHS THAT WAS DOING THE ADJUSTING IF HE HAD INSTALLED NEW HARDWARE. HE SAID NO; NOT YET. I IN TURN TOLD HIM THAT I WOULD TAKE CARE OF INSTALLING THE NEW HARDWARE. I PROCEEDED TO PULL UP THE ILLUSTRATED PARTS CATALOG TO FIND AND ORDER THE PROPER HARDWARE. I WAS ABLE TO GET THE BOLTS FROM THE ENG CHANGE KIT AND THE NUTS AND WASHER FROM STOCK. AFTER ACQUIRING THE HARDWARE; I PROCEEDED TO INSTALL THEM ON THE ENG IN ACCORDANCE WITH THE MAINT MANUAL. ONCE INSTALLED; I CHKED AND ENSURED THE INTEGRITY OF THE LINKAGES ON THE CROSS-OVER SHAFT TO WHICH THEY ATTACH. I ALSO ENSURED THERE WAS PROPER THREAD LENGTH SHOWING. IN THE PROCESS OF COMPLETING THIS; I DID NOT GENERATE A SEPARATE WRITE-UP TO COMPLETE THIS TASK SINCE IT WAS ALL PART OF ONE TASK ON THE JOB CARD AND THE JOB CARD WAS SIGNED AND COMPLETED FOR THIS TASK. THE ACFT SAT IN THE HANGAR AN ADDITIONAL 2 DAYS AFTER THIS. WHEN THE ENG AND ALL CONNECTIONS WERE INSPECTED AND WHO INSPECTED THE ENG IS NOT KNOWN BY MYSELF. THIS ENG AND THE OTHER BOTH HAD MAINT COMPLETED ON THEM AFTER THE OTHER 2 MECHS AND MYSELF WERE GONE. AS FAR AS THE INSTALLATION OF THIS ENG; THE LINKAGE BOLTS AND SECURING THE HYD LINES WAS ALL THAT I HAD TAKEN PART IN. THE CAUSE OF FAILURE; OR WHAT ACTUALLY FAILED HAS NOT BEEN MADE AVAILABLE TO ANYONE YET.
