Except LSA restriction is1320 so it does not matter what they demonstrate because it would not qualify.

I was just thinking, if a manufacture could demonstrate g loads that exceed the numbers you show, could then result in having their sport plane with gross weigh over 1320.  Could be your plane did exceed those numbers?  Say you load up your plane to 1400 and still meet the requirement? You now have marketing advantage over others.  There are planes out there that can handle over 1320.  Having a plane with higher published g loads is good, but does not necessarily translate into useful condition for the consumer.  I suspect if that could happen, then the race would be on.

I am not sure what you mean.
All ASTM compliant LSA airplanes have to meet the design criteria and they have to show +4G and -2G at gross weight as allowed max load (working) and ultimate being with a multiple of 1.5 (+6, -3). These loads are to be sustained for certain number of seconds only as these are not aerobatic airplanes.

There are various ways of showing this via static load tests or dynamic testing.

That’s correct. I would like to see (but will never happen) the LSA criteria for gross weight be established on a standard G load, say 2 and 4 which would allow a 1320 gross. If a manufactures aircraft has a G load capacity exceeding that then the gross weight could be higher until a force of 2 and 4 is reached. Not sure what is going on out there right now with manufactures, but some aircraft have low G load ratings, could some of those still list a 1320 max weight just to fit in the field of all other light sport craft?
