UNCLEAR NOTAM REGARDING RWY AND TXWY LIGHT OUTAGES AT HIS DESTINATION LURES PC12 PLT TO FLY THERE ONLY TO BE INFORMED THE ARPT IS CLOSED.

Narrative

BEFORE MY FLT TO ZZZ I CALLED THE ZZZ TWR REGARDING THE UNCLEAR NOTAM AND WAS BRIEFED ON THE NOTAM AFFECTING ZZZ. THE NOTAM READ TO ME OVER THE PHONE BY ZZZ TWR INDICATED THAT ALL ARPT LANDING AND TAXI LIGHTS WOULD BE OFF BEGINNING AT XA:00. I DISCUSSED THIS NOTAM WITH THE TWR AND THEY AGREED THAT THE NOTAM DID NOT SAY THAT THE RWY WAS CLOSED NOR THAT THE ARPT WOULD BE CLOSED. WITH THAT UNDERSTANDING; I PROCEEDED TO FLY TO ZZZ KNOWING THE WX WAS VFR; THAT I HAD A GREAT DEAL OF NIGHT LANDING EXPERIENCE AT THAT ARPT AND THAT MY ACFT LANDING LIGHTS WERE SUFFICIENT FOR A SAFE LANDING. UPON CONTACTING APCH ENRTE I WAS AGAIN NOTIFIED THAT ZZZ HAD A NOTAM FOR ARPT LIGHTS AND THAT THE NOTAM WAS UNCLEAR AS TO WHETHER THE ARPT WAS CLOSED OR WHETHER THERE WAS ACTUAL WORK ON THE FIELD. UPON DISCUSSING THIS WITH APCH; AS I NEARED ZZZ AT APPROXIMATELY XA:05; I THEN CHANGED FREQ TO ZZZ TWR TO ASCERTAIN THE ACTUAL CONDITIONS AT ZZZ AND I REACHED A MAINT PERSON WHO TOLD ME THE RWY WAS IN FACT CLOSED. AFTER PASSING OVER ZZZ; I RECONTACTED APCH AND CHOSE TO LAND AT ZZZ1. IT HAD BEEN SUGGESTED THAT I MAY HAVE DESCENDED BELOW AN APPROPRIATE ALT; OR THAT I SHOULD NOT HAVE APCHED ZZZ TO DETERMINE VISUALLY IF THE FIELD WAS OPEN. ALL PROCS WERE SAFE; APPROPRIATE AND CONTROLLED.
