Narrative:
During the course of our shift, my structures partner and I began disassembling corroded structure around rbl 12, station 395 floor frame. By the end of our shift we had removed intercostels 92) aft of station 395 (and respective attach angles/brackets) and had moved 2 pulley assemblies that were attached on the forward side of station 395 frame forward to station 4377 frame for access. (The pulley assemblies were left floating on the cables.) we had worked right up to the end of the shift and in haste when filling out our paperwork/turnover for the evening, my partner forgot to note that the pulley assembles were moved. In addition, during the relocation of the pulley assemblies, we noted that the cable runs stayed relatively centered through the frames forward and aft of station 395 frame, and that, per our maintenance practices and standard practices for this action, our interpretation was that we were not required to flag controls in the cockpit or flag the pulley assemblies. Since this work was performed we have found that the maintenance practices, as written, did in fact intend for flagging of controls and components in this instance.

Title: A B757-200 DURING A STRUCTURAL REPAIR 2 PULLEY BRACKETS WERE REMOVED AND LEFT HANGING ON THE CTL CABLES WITH NO WRITE-UPS OR CTLS FLAGGED.
Narrative: DURING THE COURSE OF OUR SHIFT, MY STRUCTURES PARTNER AND I BEGAN DISASSEMBLING CORRODED STRUCTURE AROUND RBL 12, STATION 395 FLOOR FRAME. BY THE END OF OUR SHIFT WE HAD REMOVED INTERCOSTELS 92) AFT OF STATION 395 (AND RESPECTIVE ATTACH ANGLES/BRACKETS) AND HAD MOVED 2 PULLEY ASSEMBLIES THAT WERE ATTACHED ON THE FORWARD SIDE OF STATION 395 FRAME FORWARD TO STATION 4377 FRAME FOR ACCESS. (THE PULLEY ASSEMBLIES WERE LEFT FLOATING ON THE CABLES.) WE HAD WORKED RIGHT UP TO THE END OF THE SHIFT AND IN HASTE WHEN FILLING OUT OUR PAPERWORK/TURNOVER FOR THE EVENING, MY PARTNER FORGOT TO NOTE THAT THE PULLEY ASSEMBLES WERE MOVED. IN ADDITION, DURING THE RELOCATION OF THE PULLEY ASSEMBLIES, WE NOTED THAT THE CABLE RUNS STAYED RELATIVELY CTRED THROUGH THE FRAMES FORWARD AND AFT OF STATION 395 FRAME, AND THAT, PER OUR MAINT PRACTICES AND STANDARD PRACTICES FOR THIS ACTION, OUR INTERP WAS THAT WE WERE NOT REQUIRED TO FLAG CTLS IN THE COCKPIT OR FLAG THE PULLEY ASSEMBLIES. SINCE THIS WORK WAS PERFORMED WE HAVE FOUND THAT THE MAINT PRACTICES, AS WRITTEN, DID IN FACT INTEND FOR FLAGGING OF CTLS AND COMPONENTS IN THIS INSTANCE.
