Narrative:
During the inspection of the engineering document; I inadvertently misunderstood the intent of the mechanic's portion of this engineering document was to ensure that there is a proper clearance between the clamp; wire bundle and fuel door; as the mechanic step on item X is north/a on this engineering document; my concentration was on step X which describes these tolerances. I suggest a change to this engineering document paperwork which would remove this mechanic 'north/a' on step X 'correct orientation of clamp' so that we would truly have 2 sets of eyes inspecting this item.
