HISTORY OF FLIGHT

On December 4, 2010, approximately 1245 central standard time, a Piper PA-28-140, N8320R, was substantially damaged when it collided with terrain and a fence while attempting to land at Ponca City Municipal Airport (PNC), Ponca City, Oklahoma. Visual meteorological conditions (VMC) prevailed at the time of the accident. The personal flight was being conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. The pilot was seriously injured and the passenger was fatally injured. The flight originated at Seminole (H45), Oklahoma, approximately 1115.

According to the passenger's father, his son and the pilot were flying to Ponca City to have lunch. A lineman saw the airplane approaching runway 35, but turned away and did not see the accident. According to television news reports, there was one eyewitness. Efforts to contact the witness were unsuccessful, but he stated on camera that he was headed to work and was approaching the intersection of Ash and Hartford. He saw the bottom of the plane facing him and it rolled inverted and crashed. Emergency personnel received the 9-1-1 call at 1247.

A Federal Aviation Administration (FAA) inspector who responded to the scene said he found evidence that the airplane landed on runway 35 and bounced.
