Gross Weight VS Max Takeoff Weight

[84KF]

My Kitfox 5 received it's airworthiness certificate in 1998.... and as I stated in a previous post...."It is not "licensed" or "certified" to any "gross weight".
There is nothing in any paper work on file with the FAA that mentions, or implies a "gross weight".
There is nothing in my Operating Limitations that states a "gross weight". (I will forward all the paperwork to anyone interested who requests it.)
There is no" gross weight" listed on the data plate

Review the application and registration process and show me exactly where one "certifies" the aircraft to any specific weight. http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/0ca2845e2aafffbb86256dbf00640cb2/$FILE/AC20-27F.pdf
Show where in APPENDIX 5. SAMPLE AERONAUTICAL CENTER FORM 8050-1,
AIRCRAFT REGISTRATION APPLICATION , APPENDIX 6. SAMPLE FAA FORM 8130-6, APPLICATION FOR AIRWORTHINESS
CERTIFICATE (AMATEUR-BUILT) (FACE SIDE) or APPENDIX 6. SAMPLE FAA FORM 8130-6, APPLICATION FOR AIRWORTHINESS
CERTIFICATE (AMATEUR-BUILT) (REVERSE SIDE) where one submits the "magic numbers"

"...isn't it true that although "gross weight" is indeed not on the Airworthiness Certificate, Registration, or in the Operating Limitations, it is reflected in the W&B documentation which is required by your FAA Inspector or DAR for certification?"

It may be in some (not mine) , but is it required? No....

In accordance with APPENDIX 13. SAMPLE PROGRAM LETTER TO ACCOMPANY
APPLICATION FOR AIRWORTHINESS CERTIFICATE one should answer "yes" to the question "I have weighed the aircraft to determine that the most forward and aft center of
gravity positions are within established limits. The weight and balance report is
available at the aircraft, and a copy is submitted with this application
....and the words "gross weight" or "maximum weight" do not appear in AC No.: 20-27F, CERTIFICATION AND OPERATION OF AMATEUR-BUILT AIRCRAFT , the FAA publication I have been referencing in this post.

It is then the responsibility of the PIC to ensure that the most foward and most rearward limits are not exceeded, what ever the loading situation is at the time of flight.
I have to ask this... how can one be expected to "determine" what the "maximum weight" capability, structural or otherwise, of the aircraft is at that point in time.... it has not even been test flown yet?
