N345MPipistrel Doo Ajdovscina VIRUS SW · 2014

The pilot reported that, he entered the traffic pattern for runway 4, about 800 ft above the ground. He added that, after touch down he did not see the fence that ran across the runway until the airplane was about 300 ft from it. Subsequently the airplane impacted the fence.

The airplane sustained substantial damage to the fuselage and right wing.

A review of the Okmulgee Regional Airport Federal Aviation Administration (FAA) chart supplement (02 MAR 2017 to 27 APR 2017) revealed that the runway the pilot landed on was depicted in the airport sketch with two "X" marks, which indicated the runway was closed. A review of the visual flight rules sectional chart in publication at the time of the accident revealed that the surface the pilot landed was depicted, along with the other runway surface at the airport.

The FAA Pilot's Handbook of Aeronautical Knowledge stated in part:

Marking and Lighting of Permanently Closed Runways and Taxiways

For runways and taxiways that are permanently closed, the lighting circuits are disconnected. The runway threshold, runway designation, and touchdown markings are obliterated and yellow "Xs" are placed at each end of the runway and at 1,000-foot intervals.

A review of photographs of the "X" markings on the surface the pilot landed on, showed that only fragments of faded yellow paint were visible, and what was visible did not resemble an "X".

The code of federal regulations within part §91.103 titled "Preflight Action" stated in part:

Each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight. This information must include— (a) For a flight under IFR or a flight not in the vicinity of an airport, weather reports and forecasts, fuel requirements, alternatives available if the planned flight cannot be completed, and any known traffic delays of which the pilot in command has been advised by ATC; (b) For any flight, runway lengths at airports of intended use, and the following takeoff and landing distance information: The pilot did not report that he consulted the FAA chart supplement prior to landing, which depicted the runway closed.
