Narrative:
During rii inspection of rudder power control units (PCU)'s after PCU replacements in october 2013; noted rudder was sitting low (sagging) in the aperture [cutout opening in vertical stabilizer fin for the rudder]. Inspection of rudder hinges noted some attachment hardware was missing from previous installation. Parts missing were top hat bushings on main rudder hinges. The party involved [with the] responsibility for the missing parts was a sub-contract repair station. This is the 4th or 5th documented incident of rudder parts missing from our aircraft in the last couple of years. A maintenance management person instituted changes in aircraft maintenance manual (amm) and ipc to correct this; but its starting to happen all over again. The repair station installed this rudder in july 2013. The repair installation of missing rudder attachment points was complied with on our air carrier work cards. This event took place on a crj-200 aircraft. [Contract] vendor discrepancy forms were filled out before and [now] again; as per our general maintenance manual (gmm) in regards to our continuing analysis surveillance system (cass) program.
