Narrative:

I work as an inspector in aircraft maintenance for air carrier X. I signed for the final inspection on #1 engine on aircraft. As we have done for many engine changes recently, my memory of this one is not very helpful I don't remember the final on this aircraft other than both engines were xferred from another aircraft. A 'B' check was scheduled for both engines before installation and there was some question if and when the 'B' check was done -- and the throttles rigged. The final inspection was done before all the work was done due to bad information from the preceding shift. The problem cold be controled by several things: better shift turnover, individual signoffs on the task document rather than grouping inspector signoffs altogether, and cotter key and castellated nut on the throttle linkage.

Title: A MAINT RPT ON A THROTTLE LINKAGE FAILURE THAT CAUSED AN INFLT ENG SHUTDOWN AND ACFT DIVERSION FROM ZZZ, US.

Narrative: I WORK AS AN INSPECTOR IN ACFT MAINT FOR ACR X. I SIGNED FOR THE FINAL INSPECTION ON #1 ENG ON ACFT. AS WE HAVE DONE FOR MANY ENG CHANGES RECENTLY, MY MEMORY OF THIS ONE IS NOT VERY HELPFUL I DON'T REMEMBER THE FINAL ON THIS ACFT OTHER THAN BOTH ENGS WERE XFERRED FROM ANOTHER ACFT. A 'B' CHK WAS SCHEDULED FOR BOTH ENGS BEFORE INSTALLATION AND THERE WAS SOME QUESTION IF AND WHEN THE 'B' CHK WAS DONE -- AND THE THROTTLES RIGGED. THE FINAL INSPECTION WAS DONE BEFORE ALL THE WORK WAS DONE DUE TO BAD INFO FROM THE PRECEDING SHIFT. THE PROB COLD BE CTLED BY SEVERAL THINGS: BETTER SHIFT TURNOVER, INDIVIDUAL SIGNOFFS ON THE TASK DOCUMENT RATHER THAN GROUPING INSPECTOR SIGNOFFS ALTOGETHER, AND COTTER KEY AND CASTELLATED NUT ON THE THROTTLE LINKAGE.
