Folks,
Firstly, matters Aero Commander, they are a special case, due the wing structure and the aerodynamics, if you note the several accidents in Australia, the wings have failed in downward bending, not related to G load.
Re. G loads in general, and the structural strengths referred to, these are static loads, not dynamic, and structural strength with "rolling G" reduce the G tolerance by something like 30%. In addition, the design standard for LSA ( and, as far as I know, JAR/VLA) does not include gust loading situations.
In short, your aeroplane may not be a strong as you think it is, regardless of the certification basis.
Tootle pip!!
