The load test was conducted IAW the DER's repair schedule to validate the repair. In the field, advanced equipment such as ultrasonic is not always available and so load testing us used to validate the repair. Composites never fail in airliners?? What about the vertical tail that came off of that airbus??
Tap test, ultrasonics...close monitoring of the repair process....those are your correct procedures. If you don't trust that you did the process correctly, then you're wasting your time load testing it...in my opinion. If you did the process according to the manufacturers approved methods and procedures, then it should be good to go.
If the composite repair was done according to the structural repair manual or Engineering variation authorization (EVA), since when does it need to be load tested? I've never heard of such a thing. Putting maximum ultimate load on that composite structure...asymetrically, doesn't sound like a very safe thing to do. And the guy was right below the horizontal with all that weight on it. Not good. I work on airliners and we never load test them...and the composites never fail.
what happened to the aircraft that necessitated this type of load testing on tail section only?

Interesting test, nice to see that it worked as planned
