Analysis

According to the CFI who was occupying the right seat, they had been practicing both three-point and wheel landings. He said that this particular landing was a three-point landing. He said that when they touched down, the tail-wheel shook excessively back and forth at first and then it was smooth. He stated that the airplane veered right while both of them were pushing on the left rudder. The airplane departed the right side of the runway turned around about 180 degrees, slid left into a ditch and collapsed the left main landing gear. According to the CFI, and FAA Inspector, a tail-wheel spring and associated parts had pulled apart from the tail-wheel and were later found on the runway near the point where the airplane veered right, off of the runway.
