February 09, Urbana, Ill. / Beech Bonanza

At 1400 central time, a Beech G35 was damaged during maneuvering during a local training flight out of Frasca Field. The pilot, who was not injured, had performed chandelles and lazy eights, and was performing steep turns when the rudder pedals began to vibrate while in a left turn. The pilot landed without incident. Inspection revealed the left ruddervator was loose, the left stabilator spar was cracked and the fuselage was wrinkled ahead of the ruddervators.
