A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH AN UNAPPROVED REPAIR ACCOMPLISHED TO THE L INBOARD TRAILING EDGE FLAP LOWER SKIN.

Narrative

ACR X IN ZZZ FOR A SCHEDULED B2 CHK. THE L-HAND INBOARD AFT FLAP LOWER BONDED SKIN WAS FOUND DELAMINATED AT THE OUTBOARD END FROM THE SPAR AFT 7.25 INCHES AND 4 INCHES INBOARD FROM THE EDGE. THIS AREA OF DELAMINATION IS IN THE CRITICAL AREA AS DEFINED BY SRM AND THE ACR X GENERAL PROCESS MANUAL 6-0-2-49. THIS DAMAGE WAS REPAIRED AS DESCRIBED IN ACR X GNMM 1-0-1-24 WITH THE NOTATION IN THE ACFT ELECTRONIC LOGBOOK THAT THE REPAIR WAS OUT OF LIMITS PER THE PRECEDING SPEC AND NEEDED ACR X ENGINEERING SUPPORT TO BE APPROVED. ACR X ENGINEERING PROVIDED INFO IN CONFLICT WITH THE CURRENT ACR X MAINT PROCS PUBLISHED BY ACR X. THE RESULT IS THAT THE ACFT WAS NOT REPAIRED IN COMPLIANCE WITH APPROVED INFO AS REQUIRED PER FAR PART 43 AND PART 121. I WAS REQUIRED TO ACCOMPLISH THE WORK OF THIS REPAIR BY THE ON-DUTY FOREMAN AT ZZZ1 AND DID SO WITH THE UNDERSTANDING THAT ACR X ENGINEERING WOULD PROVIDE APPROVED ENGINEERING VARIATION AUTH OR THAT THE ACFT WOULD BE FERRIED NON-REVENUE TO A LOCATION CAPABLE OF DOING THE REPAIRS PER APPROVED SPECS. THIS WAS NOT ACCOMPLISHED AND A TECHNICALLY UNAIRWORTHY ACFT WAS RELEASED BY THE STATION MAINT MGR. THIS IS A VERY COMMON PROB AND I PREVIOUSLY ADDRESSED THE PROB WITH MGMNT KNOWING THAT I WOULD EVENTUALLY BE FORCED TO ACCOMPLISH THIS TYPE REPAIR. SPECIFICALLY; DAMAGE LARGER THAN ALLOWED FOR INJECTION REPAIR AND DAMAGE IN CRITICAL AREA NOT ALLOWED TO BE REPAIRED PER THE STANDARD REPAIR; IE; GNMM 1-0-1-24 INJECTION.
