Narrative:

Reference log #X srm allowable damage page note states '2.0 maximum diameter allowed for single damage site' see detail X for damage criteria. Detail X notes that a damage site is any single area of a panel where a crack exists. I feel the damage falls into these limitations and the aircraft was airworthy per the srm reference. During re-inspection by the original inspector, it was determined the crack exceeded the limits and required more frequent inspection and repair. Technician filed report after becoming aware of the new assessment.
