Narrative:
The engineering document that I performed in july was one of the first engineering documents of this type that I had completed. I was aware the intent of the engineering document was to insure that there was no interference between the duct clamp and the fueling door between the clamp and the wiring. I think that those points were the main focus of my inspection; and they were not a problem in this case. Clrncs were good at the wiring more than .50 inch and no interference at the refueling door. I failed to realize the clamp orientation specification. I realize my error was in not focusing on the entire details of the engineering document and the more specific information on the clamp orientation. I overlooked the signoff on block 2 as a result of my failure to review the paperwork enough times before submitting it. When I was notified of the error; it had already been brought to the attention within the company and I believe that it has been corrected.

Narrative: THE ENGINEERING DOCUMENT THAT I PERFORMED IN JULY WAS ONE OF THE FIRST ENGINEERING DOCUMENTS OF THIS TYPE THAT I HAD COMPLETED. I WAS AWARE THE INTENT OF THE ENGINEERING DOCUMENT WAS TO INSURE THAT THERE WAS NO INTERFERENCE BTWN THE DUCT CLAMP AND THE FUELING DOOR BTWN THE CLAMP AND THE WIRING. I THINK THAT THOSE POINTS WERE THE MAIN FOCUS OF MY INSPECTION; AND THEY WERE NOT A PROB IN THIS CASE. CLRNCS WERE GOOD AT THE WIRING MORE THAN .50 INCH AND NO INTERFERENCE AT THE REFUELING DOOR. I FAILED TO REALIZE THE CLAMP ORIENTATION SPEC. I REALIZE MY ERROR WAS IN NOT FOCUSING ON THE ENTIRE DETAILS OF THE ENGINEERING DOCUMENT AND THE MORE SPECIFIC INFO ON THE CLAMP ORIENTATION. I OVERLOOKED THE SIGNOFF ON BLOCK 2 AS A RESULT OF MY FAILURE TO REVIEW THE PAPERWORK ENOUGH TIMES BEFORE SUBMITTING IT.
