Accident - Need a trainer ASAP

Anytime the predicted wind is over 25 knots it is essential that both wing tie-downs be used in conjunction with sturdy wing stands on both wing tips! A witness to a ASK-21 that went over on its back in a 90 knot blow, told me the ship was rocking left and right with the main wheel rising off the ground as the wings came level. As one wing rose, the tension on the tie-down cable, forced the other wing down. Sturdy tie-downs keeping the wings firmly on both wing stands will not allow this rocking oscillations. A sturdy wing stand can be made from a 5' step-ladder, legs cut to required height, with a foam pad glued to the top. A trailing edge glove placed over in an area without controls in conjunction with a 2" web strap from the T/E glove, over the leading edge down to a secure tie-down, used with 4-legged wing stands is the best way to secure your ship (IMHO)

Our experience(we lost a 2-33 to broken chain) is more is better. We use 2 independent tie downs on each main point, plus one on each tip, and most importantly, a nose tie down. If the nose can keep going up, it is much less likely to blow away.
