PIPER PA34 HAS RWY EXCURSION AT AXN.

Narrative

AFTER LNDG RWY 31 AXN; LACK OF ORIENTATION INFO CONTRIBUTED TO MY VEERING OFF THE L SIDE OF THE RWY AND STRIKING THE INTXN MARKER FOR RWY 4/22. THAT SIGN CAUSED CONSIDERABLE DAMAGE TO THE PLANE'S UNDERSIDE. LACK OF ORIENTATION INFO: 1) THE RWY AND ARPT HAD A BEAUTIFUL EVEN LAYER OF SNOW -- A BIG WHITE FLAT SHEET. 2) MY WINDSHIELD HAD ICE ON IT. THE ELECTRIC HOTPLATE PERFORMED POORLY. 3) THE ILS SYS INSTALLED 3 YRS AGO IS NOT YET ACTIVATED AT THAT ARPT. A LOC WOULD HAVE HELPED ME GUIDE THE PLANE ONCE ON THE GND. HAD THE RWY BEEN PLOWED; I COULD HAVE DISTINGUISHED IT FROM THE REST OF THE FIELD. AFTER TOUCHING DOWN; THE VISUAL CUES USED TO LAND WERE NOT DISCERNIBLE AND I WAS LEFT SEARCHING A SHEET OF WHITE FOR AN IDEA AS TO WHERE THE RWY MIGHT BE. IN RETROSPECT; I HAD FUEL ENOUGH TO RETURN TO HURON; SD. GUESS I SHOULD HAVE. I DIDN'T HAVE SUFFICIENT INFO REGARDING LCL CONDITIONS UNTIL I WAS TO MY DEST. THEN THE UPDATED FORECAST SAID THAT THE CONDITIONS WOULD BE THE SAME NO MATTER WHERE I WENT. THE SIT DID NOT LOOK UNTENABLE UNTIL I WAS ON THE GND ROLLING OUT AFTER LNDG. THEN I WAS COMMITTED TO AN INSURMOUNTABLE CHALLENGE. THE DAMAGE TO THE AIRFRAME IS THE RESULT OF POOR DESIGN OF AN OBJECT PLACED IN CLOSE PROX OF AIRPLANE OPS. AS AN ENGINEER; I KNOW I COULD DO MUCH BETTER.
