Hi All,
First time poster & first-time airplane owner, and I could use some help with a question regarding paperwork.
I'm 3rd owner of a 2013 build 750 STOL (Built after Zenith increased Gross to 1440). I'm trying to figure out where the Gross Weight Limitation should be annotated. Here's what I DO have:
1. A weight and balance sheet with handwritten empty weights, for/aft CG (Top half filled out properly) and Gross Weight of 1440; HOWEVER, it is not the same copy that's on file when the builder submitted for Special Airworthiness. That one is the same except no Gross Weight is listed.
2. A picture of the same weight and balance sheet from Pre-Phase I showing showing Gross Weight 1440 and useful load annotated.
3. An identification plate on the exterior of the aircraft that includes empty weight and gross weight of 1440.
4. Standard logbook entry after Phase I: "The following aircraft operating data has been demonstrated during the flight testing: speeds Vso 31KIAS, Vx 53KIAS, Vy 55KIAS and weight 1225lbs and CG location 454.2 at which they were obtained."
There are no other operating limits identifying any limitations on weight, and it is not an LSA.
Bottom Line: I'm personally convinced the gross weight for my airplane is 1440, but how would an inspector feel about it?
Thanks for the help!

Jack,
Welcome to the Zenith family!
Why would an inspector (what kind of inspector?) be inquiring as to the gross weight of your 750?
Do you have the Zenith drawing package with serial number for this aircraft? The design gross weight is included in the drawing package,
is this an EAB aircraft? If so, you can construct a new W&B worksheet and include the maximum gross weight and be done. If you want to, create a Pilot Information Handbook for your 750 and list it there. The max gross weight should match the Zenith design weight limit stated in the drawing package for your aircraft serial number.
And finally, just some food for thought. Do the Operating Limitations that came with your aircraft happen to include a statement similar to this: “the aircraft shall not be operated…beyond the documented weights tested” as my OL states?
