EAA Sport Aviation - March 2009

like the Unlimited and Sport Class. However, having been an EAA member for more than 30 years, it is my opinion that the builders and race teams in Formula One, with their always evolving Cassutts, Shoestrings, and one-of-a-kind racers, embody the true spirit of the EAA movement. It is no coincidence that many International Formula One members are also active EAA members.

Any recognition of that is greatly appreciated.

150, 172, 175, 182, 206, Dornier 228 (used in Antarctica by Germany), Lockheed 60 (used in Antarctica by Japan), and several Piper tri-gear. Several Cherokee Six fly in the Swiss Alps. Horsepower is the key; the more horsepower, the better the skiplane.

Wheel cutouts and wheel
penetration skis—We found that the
area behind the wheel gives little snow
support, but increases high drag. Most
wheel penetration skis increase snow
takeoff up to twice the length of wheel
skis.

Correction to Nevada
Delegation Listing

In the January issue of EAA Sport Aviation magazine in the Hotline article “EAA Opposes Dangerous Airport Access Precedent” (page 10), there is an error in the Nevada congressional delegation listing in the last paragraph. This list included Jon C. Porter (R-3rd). This is incorrect. Dina Titus defeated Porter. The correct entry is Dina Titus (D-3rd). I verified this on the Nevada Secretary of State website.

Please ensure that all of EAA has the correct listing for all of our elected officials.

Comments About Skis

Congratulations to Rick Discher for the time and expense in obtaining approvals for new skis (January 2009, “Reinventing the Ski”). Having spent 27 years designing, obtaining technical standards orders, STCs, and aircraft manufacturer approvals for a corporation that held the largest number of approvals worldwide, I am well aware of the problems he must have had.

I do have several comments on
skis:
Clamp-on skis—Approved on some
older aircraft in the United States (not
Canada), they can be dangerous due
to the fact they can pull the tire off the
wheel if the tire is underinflated.
