A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH INCORRECT GND FUELING VALVE WIRING TERMINATION.

Narrative

WHILE WORKING A TURNOVER JOB FROM PREVIOUS SHIFT ON ENGINEERING ORDER WVWX; REVISION A; ACFT XYZ; IT WAS NOTED THAT ALL WIRES HAD BEEN RUN TO PROPER LOCATION AND GND WIRES NEEDED DUAL GNDS AND INSTALLED TO ACFT GNDS. SEEING THAT A SINGLE WIRE WAS HANGING; I TERMINATED THAT WIRE WITH DUAL GND AND INSTALLED IT. DUE TO THE TIME (XA30) I NOTIFIED MY LEAD AND NEXT SHIFT LEAD OF THE PROB OF WIRES TERMINATING AT WRONG GNDS AND IT WAS STATED THAT A TURNOVER SHOULD BE WRITTEN ON WRITE-UP NOTING THE PROB; AND HE WOULD NOTIFY SUPVR FOR NEED OF ENGINEERING AUTH TO COVER THE MISROUTED WIRES. I SIGNED THE TURNOVER STATING WIRE GND WAS NOT THE TERMINATING GND FOR WIRE AND IT HAD BEEN INSTALLED INCORRECTLY. I LATER FOUND OUT THAT THE ENGINEERING AUTH HAD BEEN ISSUED AFTER ACFT XYZ HAD DEPARTED ZZZ MAINT CHK AND WAS GNDED UNTIL PROB WAS CORRECTED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED ALL OF THE INFO ON THE INCORRECT GND WIRING TERMINATION WAS PASSED ON BY A NON ROUTINE WRITE-UP AND VERBALLY TO THE LEAD SUPVR AND LCL ENGINEERING. THE RPTR SAID THE FAILURE OCCURRED AT THE ENGINEERING LEVEL WHERE THE ENGINEERING AUTH REQUIREMENT WAS MISSED AND NOT NOTICED UNTIL THE ACFT WAS RELEASED FOR SVC AND DEPARTED.
