ElectroVlasicu,
It is OK what you suggest but it is costly. Namely item 2 (replacing the part that broke) is acceptable only if it is the SAME part (same geometry and specifications i.e. materials).
One more comment, of a general nature:
There is no wing braking before the whole certification testing. If and when the test is finalized and all certification data completed and accepted by a local CAA, then it is possible to go through with wing braking.
This is not a part of required ultimate loads test.
So, Vlasicu, your suggestion is already somewhere in between the options 1, 2 and 3.
Cheers
