Your reply was a fine example of taking my observations and stretching them to extreme conclusions to support your position, not to mention the manner in which two excellent DAR's reputations were questioned.
What you didn't know about the "thirty minute" inspections is that in two of those cases the DAR had the opportunity to watch the construction of my aircraft over the span of several months via the comprehensive internet build logs documenting the progress of the build (see signature below).
That is very excessive in my opinion after I and other experienced builders have already conducted a condition inspection of the aircraft. Why would I want to shell out $900 for someone to duplicate what has already been done? We are fortunate in our area to have experienced builders (EAA Tech Counselor and A&P in some cases) who are eager to lend extra eyeballs to check a project prior to the DAR visit. I have done the same for several builders in preparation for the DAR arriving on the scene.
However, I do acknowledge some aircraft will require a more extensive inspection than others. The plastic airplanes you are familiar with are a different animal from the ultra-simple Fokker replica I recently completed. Thirty minutes would be long enough to inspect the D.VII more than once...
Best wishes on a productive and prosperous career as a DAR. Please keep in mind the experimental aircraft universe is a close-knit community that operates to a great extent on referrals.
