I had this very conversation after reading the original thread, with my mot man.
He says, in his opinion he would fail it for this citing the following reason.
Lets just say the original wing was spot welded every 2 inches, just for arguments sake, he would want to see bolts every 2 inches to satisfy himself that it was as secure as before, he did point out mot personell are not strctural engineers, so not able to from a legal point of view comment of strength/suitability of different repair techniques.
The mot is to a large extent discretionary in this respesct, others may be happy to pass, and this was only his opinion/attitude.
