A B757-200 AFTER COMPLETION OF ELEVATOR INDEX PLATE INSTALLATION TECHNICIAN NOTED ON INTERNAL INSPECTION 2 SMALL SKIN DENTS ON R SIDE LOCATED NEAR INDEX PLATE FASTENERS.

Narrative

ON JAN/THU/07; I WAS ASSIGNED TO WORK ON ACFT SHIP X. THE TASK I WAS ASSIGNED WAS TO INSTALL NEW ELEVATOR INDEX PLATES ON BOTH THE L AND R SIDE OF THE TAIL; WHICH WERE MISSING/BROKEN. THE WORK DOCUMENT I WAS WORKING ON WAS A NON-ROUTINE WORK CARD; OP NUMBER. I FOLLOWED THE MAINT MANUAL TO INSTALL THE INDEX PLATES AND TOOK GREAT CARE TO REMOVE THE ATTACHMENT RIVETS CAREFULLY. UPON COMPLETION OF INSTALLING THE INDEX PLATES I LOOKED INSIDE THE APU COMPARTMENT TO THE AREAS WHERE THE INDEX PLATES WERE INSTALLED. ON THE R SIDE INSTALLATION I NOTICED 2 SMALL DENTS IN THE LOCATION OF THE INDEX PLATE FASTENERS. I HAD ALREADY COMPLETED THE WORK DOCUMENT AT THE TIME I NOTICED THE DENTS. IT WAS THE END OF MY SHIFT; SO I NOTIFIED THE ONCOMING LEAD MECH AND POINTED THE DENTS OUT TO HIM. WHEN I LOOKED AT THE DENTS I DID NOT NOTICE ANY FURTHER DAMAGE. I USED GREAT CARE IN FOLLOWING MAINT MANUAL PROCS TO REPLACE THE INDEX PLATES; AND I BELIEVE I WAS NOT THE CAUSE OF THESE DENTS. I AM FILING THIS RPT BECAUSE I DO NOT KNOW IF THE DENTS WERE REPAIRED OR EVEN REQUIRED A REPAIR.
