Narrative:

On jun/xa/05 I was assigned with mr X to troubleshoot and repair pilot log report (L1 door hard to open). We found an external fuselage hinge access panel removed but there was no documentation of this or any other troubleshooting in the logbook or any technician's non routine write-up. A part was ordered for the door but during our troubleshooting it did not appear that this part was defective. The door operation did not feel abnormal to our experience with other B757 entry doors. We solicited the help and opinion of other mechanics and both crew chiefs as to the operation of the door and they all felt it was operating normally. We then lubed the door. The only item we could find was the pin indicator on the dampening snubber extended. We talked to technical services and agreed that the snubber would in no way impede the operation of the opening of the door and that they would put an item in to have the part replaced. This was the first write-up on the door and there was no prior history of the problems with it. Since in our troubleshooting we found no structural or mechanical problems; no damaged linkages or binding and no problem with the part that was ordered; and since the door operation was normal not only to myself and mr X; but to other mechanics and crew chiefs; we felt confident with our findings and lubricated the door. By submitting this letter; I wish to report my findings. Contributing factors: supervisor turnover sheet was not available at the hangar; and the line mechanic did not document his findings or troubleshooting.
