Narrative:
On monday; air carrier X was in for a C1 check. I had the visual skin lap inspection. I was told by my supervisor around lunch on gravis on may/wed/06 I missed a skin crack. We were short an inspector that night so my workload was increased. I had fuselage; tail; air conditioning bays; cargo bins; walkaround; east&east compartments; and picked up the APU and visual skin lap. While doing this inspection with the extra work; you get interrupted. This air carrier X had just came out of structures.
