Narrative:

I was informed by management in that I misworded the corrective action on a write-up for a B767-200 aircraft during a b-check. The items on the write-up were: 'left-hand and right-hand aft fairing strut fire seal is damaged'. I repositioned/secured the left-hand and right-hand pylon aft skirt fairing aerodynamic high temperature bulb seal. When I signed-off the items; I misworded the sign-off. I intended to write: 'reposition/secured bulb seal'. Instead I wrote 'replaced/secured fire seal' and quality assurance (inspection) bought back [inspected] the items with no questions asked.I know in order to replace the seals; the nozzle sleeve would have to be removed from the engine. The aircraft flew 16 legs (flights) overnighting four times with no pylon seal discrepancies. During a review; [there was a] suggestion the seal was damaged. I asked why the aircraft was flying with a known discrepancy with no documentation; the question was not answered. I was informed that an employee in the quality assurance department knew of the discrepancy and did not document the items per company policies and procedures; and continued to allow the aircraft to fly. The seals were changed later.
