Bob...I couldn't agree w/ you more...and...there are both positives and
negatives to the regs and different approaches used by the
people-who-are-paid-to-worry in the UK and the US.
In my circumstances, I was the only person I had to satisfy...and I was
able to do so by imposing a 1500# compression load on my little riser
using a hydraulic press and very heavy duty cargo strap...but the net
effect was but a conscientious effort to ensure that the orientation of
the imposed loads was accurate and the load path into the airframe did
not change...nonetheless, a far cry from engineering proof loading.
