Narrative:
Ship had a major repair to the station 1720 pressure bulkhead that required a break ring slice and skin repair. Myself and 4 other technicians turning over to each other daily over a period of 8 days performed the work. The repair was complete with the exception of a pressure leak check, test flight and final approval of the repair method from boeing engineering. The preliminary repair instructions and non routine cards for the repair and slice were complied with oct/tue/03 and signed off by myself and one of the other technicians. Quality control had also complied with their respective signoffs. On the morning of oct/thu/03, a technician notified me that the sealer in the area of the repair slice had been removed to comply with a boeing request for photos of the repair. It was at this time I became aware of the fact that no paperwork (non routine card) was generated to remove the sealer from this area. I contacted work center supervisor with my concern regarding the fact that our repair had been altered with no paperwork for documentation. He informed me that no documentation was necessary because he was 'handling it' I spoke to supervisor later in the morning regarding my concerns of undocumented maintenance being performed on a fresh repair. He stated he would write a card concerning the removal of the sealer. As of the writing of this report, I have been unable to conform that a card was written.
