PLT OF AN SMA SEL ACFT STRUCK WIRES DURING LNDG AT A PVT UNCHARTED ARPT RESULTING IN DAMAGE TO THE ACFT VERT STABILIZER AND RUDDER.

Narrative

MY SON AND I DEPARTED THE AKRON ARPT ON A LCL PLEASURE FLT IN MY PERSONAL AIRPLANE. WE DECIDED TO PRACTICE A LNDG AT A PRIVATE AIRSTRIP 5 NM ESE OF DARIEN; NY. WE FLEW OVERHEAD AND BOTH DISCUSSED AND SCANNED FOR THE POSSIBILITY OF WIRES NEAR THE APCH END OF THE RWY. WITH A LIGHT WIND FROM THE NW; I ELECTED TO LAND TO THE N. UNTIL NOW; WE HAD SIGHTED WIRES TO THE W ALONG THE ROAD; BUT COULD NOT SEE POLES OR WIRES OR BALL MARKERS AT THE APCH END OF THE RWY. I TURNED A NORMAL FINAL APCH AND WAS NEAR THE POINT OF FLARING TO LAND WHEN I SAW A SET OF WIRES DIRECTLY AHEAD. THESE WIRES WERE LOCATED ABOUT 200 FT DOWN THE RWY; AWAY FROM THE ROAD. THE VERT FIN OF MY AIRPLANE CONTACTED THE WIRES; AND I WAS ABLE TO COMPLETE THE LNDG. WE COULD NOT SEE THE WIRES OR THE POLES FROM THE AIR BECAUSE THEY WERE NOT MARKED AND BECAUSE THE PWR POLES WERE LOCATED IN SHADOW ALONG A HEDGEROW TO THE E; AND ON THE SIDE OF A LARGE TREE TO THE W. IN ADDITION; THE SPAN OF THE WIRES WAS QUITE LONG; NEARLY 300 FT. BTWN POLES. THESE WIRES WERE DISPLACED 200 FT FROM THE ROAD; AND THERE WAS NO DISCERNABLE PATTERN OF POLE SPACING ALONG THE ROAD. THE FAA SHOULD MAKE AVAILABLE SPECS FOR MARKING DEVICES TO ALL PRIVATE STRIP OWNERS AND PWR COMPANIES; AND MANDATE THEY SHOULD SUITABLY MARK ALL WIRES WITHIN A SPECIFIED DISTANCE OF ANY ACFT LNDG SURFACE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE WIRES STRUCK WERE HANGING ACROSS THE RWY LNDG AREA APPROX 20 FT ABOVE THE GND. THE ACFT STRUCK THE WIRES WITH THE VERT STABILIZER WHICH PULLED THE ACFT TO THE GND; RIPPING THE VERT TAIL- PLANE ALMOST OFF; AND PULLING DOWN THE WIRES AND 1 POLE. THE WIRES CAME TOGETHER AND SHORTED OUT THE ELECTRICITY TO THE SURROUNDING AREA. HE BELIEVES THAT EVEN THOUGH THE ARPT IS PVT AND UNCHARTED; IT SHOULD BE REQUIRED BY FAA TO MEET STANDARDS FOR WIRE LOCATION AND MARKINGS. HE STATED THAT THE FAA FSDO INVESTIGATED THE ACCIDENT BY ORDER OF THE NTSB AND DECLARED IT AN INCIDENT.
