>To me, when you sign off your Lancair after the test phase
25 or 40 hours as (to paraphrase) "fully tested", it ought to have been.<

I refer you to Advisory Circular AC-90-89 page 5-9, the Amateur-Built
Aircraft Flight Testing Handbook.  Quote:

Caution #1  --  If the manufacturer/designer of your aircraft  has not
demonstrated satisfactory spin characteristics and safe recovery, avoid all
types of high angle of attack flight testing and placard the aircraft:
"spins prohibited."

BTW, you are signing off the aircraft as "adequately tested" not "fully
tested."  See AC 90-87.  Also please note the E-mail subject "stall/spin
testing".  Of course you test for falps down slow flight handling, Vx, Vy,
best glide, etc.

I'm not trying to be cute about this.  I just don't like the thought of any
one of our community being misled by suggestions that we must do flight
testing that simply isn't required and in some instances may not be safe.
