Glad you're getting close Patrick. Hopefully congrats will be in order on Wed. next.
Some thoughts-
My guy was very thorough on paper work correctness. Much less about the physical build.
My inspection took no more than 3 hours. Paperwork being in order is crucial to the FAA.
All "T's" crossed and "I's" dotted as they say. Truth be told the time spent looking at my aircraft took about the same amount of time as a thorough
pre-flight.
I had at least two EAA Tech-Counselor inspection forms filled out and signed for his perusal. He seemed to like those.
Having a build photo album was very helpful. He could see I was involved in all aspects of the build. Maybe with the new digital age a "pad" with lots of build photos would be the modern equivalent.
Placarding was important to my DAR. Labeling switches ect. , fuel tanks placarding with volumes and octane ratings for your engine near the fuel filler openings, passenger warning plaque ect.
My "Experimental's" were hand painted below my door openings but he felt they did not show up adequately and I had to have them hi-lighted with darker shadowing paint. Thank you DesertFox6 for saving the day.
You just never know what your guy will like or dislike.
Final thought-
Please don't count on your inspector to find any problems or safety issues that you might have missed during the build. Just because they have a FAA badge does not make them an expert on your make & model.
Best wishes for next Wednesday.
