Analysis

Just prior to touchdown a thorp T-18 and a Piper collided in flight. The Piper struck the thorp from above at aprx 10 ft AGL over the threshold. The thorp landed without further incident. The Piper completed a normal landing until the propeller contacted the runway. The nose gear was sheared off from contacting the propeller of the thorp. Neither pilot reported having seen the other airplane. The Piper did not have operable radios and the Piper pilot reported flying the traffic pattern 300 ft higher than published.
