Narrative:
Changed springs on r-hand outboard droop quadrant that later on that week was reject tagged #XXX. #Wzwz was originally written up. Reject tag was signed off by quality assurance supervisor. It has come to my attention that a detent breakout torque check must be accomplished after changing these springs. According to original write-up, this check has not been accomplished. Maintenance manual reference 27-11-38-4. Callback conversation with reporter revealed the following information: the reporter stated the unit was a B767 right outboard droop quadrant and the items replaced were 2 springs on the unit. The reporter said the unit was not torque checked per the maintenance manual and was installed. The reporter said the aircraft was test flown with no problems. The reporter stated the error was caught prior to entering revenue service and had the required check accomplished.
