I think, but can not yet be certain (because I have not seen a 787 SRM), that the 787 SRM will provide for:
1. Field Repairs using titanium parts attached over damaged composite structure with mechanical fasteners (like a scab patch on aluminum structure), and
2. Maintenance Base Repairs using composite bonding processes with all of the BAC Process Spec controls that assure that proper environmental controls, equipment, instrument calibrations, operator skills, QC checks (and double checks, etc.), material specs, and testing and lots of record keeping all are done.
The scab patches are ugly and do not need to last the life of the arframe, only to the next C or D Check where skin panel replacement and/or proper flush patches are done. The same will be true of the 787 process.
