Dear Sirs,
I am sure that the pilots of the airbus that crashed after takeoff in the New York area thought that as long as they were below manoevering speed they could do no damage with rapid left and right full rudder applications.They and all their passengers are dead!
No certification of an aircraft (FAR 23 or 25) has ever required testing about the yaw axis with regards to Va. Va is only tested as relates to full deflection of the elevator and aileron surfaces.
The rudders on our Skymasters can exert tremendous forces on the boom/wing interface. Just look at the skin thickness and fastner size at the the wing/boom joint.
We would all be wise to remember that even the youngest Skymaster is now over 20 years old, mine will be 42 this December. As these aircraft age perhaps pushing the edges of the envelope is not the best idea.
Regards
James T Grant
