Narrative:
I was working flight xy when I was told by my crew chief to help repair a hydraulic leak on aircraft xyz, after my aircraft departed. I arrived at aircraft xyz when another mechanic just finished installing a plug with a new o-ring on the #3 spoiler actuator. He was covered in hydraulic fluid so I finished re-torqueing and safety wiring the plug. After operations checking the system no leaks were detected and the aircraft was dispatched. While cleaning up, the mechanic who took out the plug noticed a filter in the bottom of a bucket of hydraulic fluid. We notified our immediate supervisor. After serious discussions with maintenance control and flight dispatch, the aircraft was allowed to continue on its trip.
