Narrative:
I was assigned to perform engineering order as an inspector. I failed to report on findings that a doubler was present. This event happened a long time back and I really don't know how I missed this doubler. The paperwork stated to report doublers more than 20 inches. Perhaps I measured incorrectly with conditions being what they were (top of aircraft was very wet) and it was hard to hang out of the cherry picker at just the right angle. This inspection should be done in a hangar with better access and dryer conditions.
