Speed Tape doesn't restore the structural strength of the damaged area, that is the overriding purpose of ABDR (now Expedient Repair). As mentioned by Longer Ron, the internal structure needed to be repaired to restore the integrity of the internal structure. I had a chat with the guy that did the repairs on what they used and how it compared to the repairs I was involved with during GW1. Standard external ABDR patch covering the holes with internal structure repaired by sheet and internal rib load paths replaced by an external stringer and the old ABDR rivet formula. Stuff I was taught on the crash course we did at Abo in 1990.
