Narrative:
On the night of mar/mon/04, I was assigned aircraft. At that time I was on probation and had been with the company since feb/mon/04. I was still getting familiar with the paperwork and work routines at air carrier. That night I was troubleshooting a fire detection MEL on the #1 engine. One of the fire loops would not test. While examining the detector wiring for problems I found the starter duct standoff hanging loose disconnected from the starter duct. I informed the lead and the supervisor and upon completing the repair for the MEL began looking up the missing hardware for the starter duct standoff. The parts were unavailable. As I recall filling out the non routine card, I supplied the part numbers and ipc references. It was my understanding that maintenance control was aware of the situation and that arrangements were being made to take care of the problem at the next downline station where the parts were available. I didn't want the standoff just hanging loose so I communicated to lead I would be safety wiring the standoff in place. My reasoning at the time was to temporarily secure the loose standoff to avoid damage to the adjacent structure and that the problem was being scheduled to be fixed later that day downline, where the parts were available. It was my assumption at the time that because maintenance control was aware of the situation and a non-routine card was being written against this discrepancy that this procedure was ok.

Title: A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH AN INTERIM AND UNAPPROVED REPAIR TO THE L ENG STARTER DUCT STANDOFF.
Narrative: ON THE NIGHT OF MAR/MON/04, I WAS ASSIGNED ACFT. AT THAT TIME I WAS ON PROBATION AND HAD BEEN WITH THE COMPANY SINCE FEB/MON/04. I WAS STILL GETTING FAMILIAR WITH THE PAPERWORK AND WORK ROUTINES AT ACR. THAT NIGHT I WAS TROUBLESHOOTING A FIRE DETECTION MEL ON THE #1 ENG. ONE OF THE FIRE LOOPS WOULD NOT TEST. WHILE EXAMINING THE DETECTOR WIRING FOR PROBS I FOUND THE STARTER DUCT STANDOFF HANGING LOOSE DISCONNECTED FROM THE STARTER DUCT. I INFORMED THE LEAD AND THE SUPVR AND UPON COMPLETING THE REPAIR FOR THE MEL BEGAN LOOKING UP THE MISSING HARDWARE FOR THE STARTER DUCT STANDOFF. THE PARTS WERE UNAVAILABLE. AS I RECALL FILLING OUT THE NON ROUTINE CARD, I SUPPLIED THE PART NUMBERS AND IPC REFS. IT WAS MY UNDERSTANDING THAT MAINT CTL WAS AWARE OF THE SIT AND THAT ARRANGEMENTS WERE BEING MADE TO TAKE CARE OF THE PROB AT THE NEXT DOWNLINE STATION WHERE THE PARTS WERE AVAILABLE. I DIDN'T WANT THE STANDOFF JUST HANGING LOOSE SO I COMMUNICATED TO LEAD I WOULD BE SAFETY WIRING THE STANDOFF IN PLACE. MY REASONING AT THE TIME WAS TO TEMPORARILY SECURE THE LOOSE STANDOFF TO AVOID DAMAGE TO THE ADJACENT STRUCTURE AND THAT THE PROB WAS BEING SCHEDULED TO BE FIXED LATER THAT DAY DOWNLINE, WHERE THE PARTS WERE AVAILABLE. IT WAS MY ASSUMPTION AT THE TIME THAT BECAUSE MAINT CTL WAS AWARE OF THE SIT AND A NON-ROUTINE CARD WAS BEING WRITTEN AGAINST THIS DISCREPANCY THAT THIS PROC WAS OK.
