Narrative:

I was called to check the right-hand engine pylon and eddy current the #6 fastener hole in the back by the drag brace. The hole was written up on a write-up form; because the dock (hangar) uses the write-ups to simplify the process by doing one hole at a time. I did look at the engineering order (eo) to verify the proper location of the hole; but did not notice that there was titanium in the hole. I set my test equipment for aluminum and steel only. While at work; I overheard some of my co-workers talking about the fact that there were three different metals in this area. It was then; that I realized I only set up my tester for two of the metals. The dock uses write-ups to simplify the process. I think it would be better to simplify the engineering order paperwork so write-ups do not have to be generated for work that is supposed to be performed from an engineering order.

Title: An Inspector reports he was called to check the right-hand engine pylon and to Eddy Current the #6 hole by the Aft Drag Brace; but failed to notice the Engineering Order reference to Titanium in the hole. He had set the Eddy Current Inspection machine for only two metals; Aluminum and Steel.
