Aircraft; Company Policy; Human Factors
While accomplishing [Maintenance Document Number] for vertical bounce I discovered excessive wear at the horizontal stabilizer hinge bearings. [Maintenance Control] locked the log page and the Aircraft was ferried to ZZZ1 for permanent repair. Later [Maintenance Control] decided to continue the aircraft in revenue service with a [Deferral] for up to 100 cycles. On [Date] the aircraft was taken out of service for the same issue where it is currently being repaired. This is a known issue on the 737-800 fleet at our company and other carriers; Boeing has an FTD (Fleet Team Digest) 737NG-FTD-55-13001. With this amount of wear the Aircraft should have been repaired immediately at ZZZ1; the Aircraft should not continue in revenue service. A fleet campaign should be accomplished to check for failure of the horizontal stabilizer hinge bearing.
