PA24 PILOT REPORTS LANDING AT CGZ AT NIGHT AND FINDING A DISABLED ACFT ON THE EDGE OF THE RWY.

Narrative

WAS ON A LCL FLT. STOPPED BY CGZ FOR GAS AS USUAL. RWY MARKER LIGHTS NOT WORKING BUT ILS LIGHTS (THE RABBIT) AND OTHERS WORKING. THIS HAPPENS ALL THE TIME AT NIGHT AT THE SMALLER UNCTLED ARPTS IN ARIZONA -- THE ARPT PERSONNEL FORGET TO TURN ON THE LIGHTING SYS OR LEAVE THE ROTATING BEACON OFF ETC SO I DID NOT THINK MUCH OF IT AS ABOUT HALF THE TIME I GO INTO A SMALL UNCTLED ARPT AT NIGHT IN AZ AT LEAST SOME OF THE LIGHTS DON'T WORK. I HAVE 2 HIGH INTENSITY LIGHTS ON THE END OF EACH WING SO I USUALLY DON'T HAVE ANY PROB. ON ROLLOUT AFTER SLOWING DOWN AND LOOKING FOR A TXWY (GOING SLOW -- 10 OR 15 MPH) I NOTICED SOMETHING OFF TO THE S SIDE OF THE RWY ON THE RWY. IT WAS A TWIN -- MAYBE AN APACHE THAT APPEARED TO HAVE BELLIED IN. IT APPEARED THERE WERE REMNANTS OF FLARES ON THE RWY SO I'M GUESSING EITHER IT HAPPENED AFTER HRS OR FLARES WERE PUT OUT BUT HAD EXPIRED. THE AIRPLANE WAS FAR ENOUGH DOWN THE RWY THAT THERE WAS PLENTY OF RWY FOR ME TO TKOF AGAIN. IN ANY EVENT; I'M NOT SURE WHAT I COULD HAVE DONE DIFFERENTLY TO KNOW THE RWY WAS IMPAIRED. AS STATED EARLIER; THIS WAS A LCL FLT SO I DON'T NORMALLY GET A BRIEFING OR FILE A FLT PLAN FOR LCL FLTS. IT'S A COMMON OCCURRENCE TO HAVE SOME PART OF THE LIGHTING NOT WORKING AT MOST OF THE UNCTLED ARPTS IN AZ. THEREFORE THERE WAS NO REASON TO THINK THE RWY WAS IMPAIRED. THIS MAY HAVE BEEN ONE OF THOSE THINGS WHERE THE ACCIDENT OCCURRED AFTER HRS AND NO ONE REALLY KNEW YET. IT WOULD HELP TO HAVE SOMETHING ON CTAF IF AN ARPT IS UNEXPECTEDLY CLOSED. MAYBE EVEN A REPEATING RECORDING STATING THE ARPT IS CLOSED; DON'T LAND HERE. IN MY PERSONAL OPINION; JUST HAVING ONE PART OF THE LIGHTING OFF IS NOWHERE NEAR SUFFICIENT. MAYBE THERE WAS SOMETHING ELSE I SHOULD HAVE/COULD HAVE DONE BUT HAVING GONE OVER IT IN MY MIND AGAIN AND AGAIN I'M JUST NOT SURE WHAT ELSE I COULD HAVE DONE. I WISH THERE WAS A STANDARD AND RECOGNIZABLE WAY TO CLOSE AN UNCTLED FIELD AT NIGHT IN THE EVENT OF A PROB (SUCH AS AN AIRPLANE ON THE RWY) THAT WOULD PREVENT SOMEONE FROM LNDG).
