I don't fly ice anymore but should you encounter it flying the 10, the article provides some does and don'ts. Having flown a Cessna Cardinal for about 30 years and built a Glastar in addition to a 10, I have learned a little about tail stalls. I first heard of the problem and considered it back when the C177 did not have the slots in the tail. Pilots were trying to land the Cardinal and in the flare with flaps deployed, they stalled the horizontal stabilator. The result was a rapid pitch downward and a damaged nose gear. This problem can also be demonstrated in the Glastar. It can be built improperly with the wrong horizontal stabilizer angle of incidence and a tail stall can be experienced in the flare even without flaps deployed. Mine was built properly but the pilot who made first flight in my Glastar made the approach at 10-20 knots faster than normally required and no flaps to protect himself from such a potential problem. The referenced article also notes that tail stalls can also be experienced with flaps deployed and ice on the tail. The problem exists both for high and low wing aircraft. My plans are to stay out of ice but should I encounter and experience a tail stall I plan to be prepared.
