Narrative:

On jan/wed/07; on aircraft X I was assigned to the elevator tab duties. A problem was found with the r-hand elevator tab hinge bushings at all position (1-4). The problem was corrected at all position. After correcting the discrepancy; a free-play check was performed and passed. The problem was brought to my attention that an engineering authority/authorized was not complied with. Witness putty was applied to the bolt heads as well as a system inspection. This engineering authority/authorized was not issued to aircraft X and needs to be complied with. The reason this problem happened is the paperwork is very complicated and difficult to understand.
