William "Randy" Humble, 60, had been flying a Lake Amphibian DA-4-550 performing an aerial show with another aircraft around 5:30 p.m. Saturday.

Why does it say, experimental on the edge of the wing when the float is down if it's a production plane?

Sympathies to the family and friends.

My brother is a GA pilot and I'm glad he doesn't fly anymore.

If my memory serves me correctly, the experimental version is home built from plans.

Also read Technical Resources from the Lake Amphibian Flyers Club.
There's a lot of good links there, if you want more information.
