A B737-400 WAS REQUIRED TO BE MAINT FERRIED TO A MAINT STATION DUE TO FAILURE OF TECHNICIANS TO SIGN OFF AN OPEN LOG BOOK INSPECTION WRITE-UP.

Narrative

ON OCT/SAT/05 I WAS INFORMED THAT ACFT X WAS FERRYING FROM ZZZ1 BECAUSE OF AN OPEN LOG BOOK PAGE. IT IS POSSIBLE THAT I AM RESPONSIBLE FOR SIGNING OFF THAT PAGE. WHILE I'M NOT SURE; I WAS WORKING THE ENGINEERING ORDER ASSIGNED THAT REQUIRED A NON ROUTINE WRITE-UP X TO BE OPENED IF THE INSPECTION PUTTY OF THE ELEVATOR TAB CTL ROD WASN'T PRESENT. I TIED INTO THE JOB FROM TECHNICIAN WHO HAD WRITTEN A WRITE-UP Y AT THE INSISTENCE OF THE INSPECTION DEPT BECAUSE OF CONFUSION OVER WHETHER THE LINE MAINT WAS ALLOWED TO WRITE NON ROUTINE WRITE-UP X'S. THE TECHNICIAN THEN PROCEEDED TO SIGN OFF THE R-HAND TAB INSPECTION PUTTY DISCREPANCY LEAVING THE L-HAND OPEN BECAUSE OF QUESTION OVER WHETHER WE WERE GOING TO CHANGE IT DUE TO ITS FAILURE OF A FREE PLAY INSPECTION. IT WAS WITHIN LIMITS FOR DEFERRAL. HE THEN DEFERRED THE L-HAND TAB AND WENT HOME. AFTER FINDING THE TAB CRACKED IT BECAME APPARENT IT HAD TO BE CHANGED. I BELIEVE MR Y AND I CHANGED THE TAB GETTING MR Z TO RII THE TASK; COMPLETED THE ENGINEERING ORDER AND SIGNED OFF THE WRITE-UP X FORGETTING A WRITE-UP Y HAD BEEN WRITTEN. (IT WAS IN A SEPARATE LOG BOOK. WE HAD STARTED A NEW LOG BOOK BECAUSE OF THE AMOUNT OF DISCREPANCIES.) MR Y WENT HOME AND I STAYED OVER AND WENT ON THE TEST FLT. THE TEST FLT FAILED AND I STAYED WORKING WITH A MECH; MR A. WE ADJUSTED THE TAB AS REQUIRED BY THE MAINT MANUAL AFTER A TEST FLT. MR B AND MR C INSPECTED THE WORK AND I WENT HOME. I DISTINCTLY REMEMBER INSPECTION PUTTY BEING REAPPLIED AFTER WE ADJUSTED THE TAB RODS. THE NEXT MORNING; I WENT ON THE TEST FLT AND THE ACFT CHKED GOOD. BECAUSE THE AIR CREW FOUND THE OPEN LOG BOOK ITEM; ZZZ1 WAS IN QUESTION ABOUT WHETHER THE ENGINEERING ORDER HAD BEEN PROPERLY ACCOMPLISHED AND WENT UP AND LOOKED AT THE ELEVATOR TAB CTL RODS AND SAID THEY ONLY FOUND A LITTLE INSPECTION PUTTY ON THE RODS. AFTER FERRYING THE ACFT BACK; WE HAD THE SUPVR GO UP TO THE PLANE AND INSPECT THE CTL RODS AND HE WAS ABLE TO CONFIRM THAT THE CTL RODS DID IN FACT HAVE INSPECTION PUTTY ON THEM BUT WAS NOT COVERING THE WHOLE ROD END.
