Have they stressed the 14 gear for 2050 lbs MTOW?
Or have they added some margin?
Would the gear be a limiting factor when it comes to increasing the mtow because it's only tested for 2050lbs?
The limiting factor to the published gross weight is the entire airplane.
A proper design process uses the design gross weight in designing everything... airplanes aren't designed and then tested, and then a max weight set based on what the weakest was shown to be as a result of the tests done.
There is a complete stress analysis for an RV 7 (if I remember correctly) done by an engineering student in Germany. The analysis is available from the OUV (the German version of the EAA). www.ouv.de
