I'm fairly sure that a "civil" test by a certified company would be more than adequate.
A "demand" by asra to only use "casa approved" might be a tad &^%$#@ overkill. The "certification" of a company to do these type tests should be it.
Aero company testing would be near the cost of throwing it away, and just getting a new bar. [ Especially after 99.9% of bars would be tested defect free ]. Testing for cracks, yes good call.
Maybe we could get feedback from the asra guys who frequent here. [ management guys ]
