Narrative:

While assigned to a 48 month inspection on a hawker 600, I encountered a work stoppage for parts and to facilitate other maintenance. While at this work stoppage, I was assigned to assist on a 'C' check inspection on a falcon 10 serial XXXX, card code xyz. Later that morning, hawker parts and equipment came in which required that I return to the 48 month inspection on the hawker 600. I bagged and tagged all hardware, probes, electrical boxes, and panels. All removed parts and panels were stored, and the technician was given a complete turnover as to what had been done, my stopping point, and why I was stopping. Days later, I was asked to re-install the probes and electrical boxes. I was assured that the operation had been completed and inspected. In good faith, I re-installed the probes and electrical boxes and signed off the card. On sep/xa/97 I was informed that some small corrosion was discovered in the feeder tank during another inspection at a different location. I traveled to the location and inspected the feeder tank and verified a small spot of corrosion existed on the forward l-hand corner of the right feeder tank. From this occurrence I've learned that good faith and assurances have their place, but not in aircraft maintenance. I've always double-checked all maintenance and completed all tasks assigned. I will continue to double-check my work and not be assured or assume anything unless I've personally checked and verified the maintenance myself.

Narrative: WHILE ASSIGNED TO A 48 MONTH INSPECTION ON A HAWKER 600, I ENCOUNTERED A WORK STOPPAGE FOR PARTS AND TO FACILITATE OTHER MAINT. WHILE AT THIS WORK STOPPAGE, I WAS ASSIGNED TO ASSIST ON A 'C' CHK INSPECTION ON A FALCON 10 SERIAL XXXX, CARD CODE XYZ. LATER THAT MORNING, HAWKER PARTS AND EQUIP CAME IN WHICH REQUIRED THAT I RETURN TO THE 48 MONTH INSPECTION ON THE HAWKER 600. I BAGGED AND TAGGED ALL HARDWARE, PROBES, ELECTRICAL BOXES, AND PANELS. ALL REMOVED PARTS AND PANELS WERE STORED, AND THE TECHNICIAN WAS GIVEN A COMPLETE TURNOVER AS TO WHAT HAD BEEN DONE, MY STOPPING POINT, AND WHY I WAS STOPPING. DAYS LATER, I WAS ASKED TO RE-INSTALL THE PROBES AND ELECTRICAL BOXES. I WAS ASSURED THAT THE OP HAD BEEN COMPLETED AND INSPECTED. IN GOOD FAITH, I RE-INSTALLED THE PROBES AND ELECTRICAL BOXES AND SIGNED OFF THE CARD. ON SEP/XA/97 I WAS INFORMED THAT SOME SMALL CORROSION WAS DISCOVERED IN THE FEEDER TANK DURING ANOTHER INSPECTION AT A DIFFERENT LOCATION. I TRAVELED TO THE LOCATION AND INSPECTED THE FEEDER TANK AND VERIFIED A SMALL SPOT OF CORROSION EXISTED ON THE FORWARD L-HAND CORNER OF THE R FEEDER TANK. FROM THIS OCCURRENCE I'VE LEARNED THAT GOOD FAITH AND ASSURANCES HAVE THEIR PLACE, BUT NOT IN ACFT MAINT. I'VE ALWAYS DOUBLE-CHKED ALL MAINT AND COMPLETED ALL TASKS ASSIGNED. I WILL CONTINUE TO DOUBLE-CHK MY WORK AND NOT BE ASSURED OR ASSUME ANYTHING UNLESS I'VE PERSONALLY CHKED AND VERIFIED THE MAINT MYSELF.
