Narrative:
A crack was found at body station (bs) 500B; between stringer (str) 20-right and str 21-right; migrated from a grommet hole. An engineering authorization (ea) was issued and worked and completed. I closed out the non-routine (nr) write-up; noting all 4 steps on the ea had been completed. All parts were complete and inspected.since the ea had step 6 as a time restricted deferral; with no inspection stamp block; it was overlooked and not transferred to the nr write-up and therefore was overflown.
