Narrative:
At start of shift, I was given write-up zxxxy and copy of srm 53-00-11, figure 202. Working with my lead and an engineer, I was told how to proceed with the repair. Trusting their yrs of experience and expertise, I cut out the damage to include removing skin in 3 stringer bays. I made a good cut-out with 1 inch radius corners, didn't nick stringers. Inspection approved that damage was properly removed. This was the extent of my involvement with the repair. I later found out, the cut-out was beyond limits. It was to have only been in 1 stringer bay. An engineer looked at the cut-out, and made a statement on back of write-up that cut-out was ok. The doubler was installed by workers on a later shift, per srm 53-00-11. I was told by a fellow worker the srm used was for a small repair and there was a different srm reference for a large repair. The lead did not want to reprocess the write-up for a different srm reference. The cut-out section was approximately 5 inches by 10 inches, over 2 stringers. I believe the final repair was safe for service. Engineering followed the progress on repair, inspection returned the plane to service.
Original NASA ASRS Text
Title: AN AIRBUS A320 WAS RELEASED FROM HVY MAINT WITH A SKIN REPAIR NOT IN ACCORDANCE WITH THE STRUCTURAL REPAIR MANUAL, BUT WITH ENGINEERING REPAIR APPROVAL.
Narrative: AT START OF SHIFT, I WAS GIVEN WRITE-UP ZXXXY AND COPY OF SRM 53-00-11, FIGURE 202. WORKING WITH MY LEAD AND AN ENGINEER, I WAS TOLD HOW TO PROCEED WITH THE REPAIR. TRUSTING THEIR YRS OF EXPERIENCE AND EXPERTISE, I CUT OUT THE DAMAGE TO INCLUDE REMOVING SKIN IN 3 STRINGER BAYS. I MADE A GOOD CUT-OUT WITH 1 INCH RADIUS CORNERS, DIDN'T NICK STRINGERS. INSPECTION APPROVED THAT DAMAGE WAS PROPERLY REMOVED. THIS WAS THE EXTENT OF MY INVOLVEMENT WITH THE REPAIR. I LATER FOUND OUT, THE CUT-OUT WAS BEYOND LIMITS. IT WAS TO HAVE ONLY BEEN IN 1 STRINGER BAY. AN ENGINEER LOOKED AT THE CUT-OUT, AND MADE A STATEMENT ON BACK OF WRITE-UP THAT CUT-OUT WAS OK. THE DOUBLER WAS INSTALLED BY WORKERS ON A LATER SHIFT, PER SRM 53-00-11. I WAS TOLD BY A FELLOW WORKER THE SRM USED WAS FOR A SMALL REPAIR AND THERE WAS A DIFFERENT SRM REF FOR A LARGE REPAIR. THE LEAD DID NOT WANT TO REPROCESS THE WRITE-UP FOR A DIFFERENT SRM REF. THE CUT-OUT SECTION WAS APPROX 5 INCHES BY 10 INCHES, OVER 2 STRINGERS. I BELIEVE THE FINAL REPAIR WAS SAFE FOR SVC. ENGINEERING FOLLOWED THE PROGRESS ON REPAIR, INSPECTION RETURNED THE PLANE TO SVC.
