PVT PLT OF A BEECH 36 LANDED AT A TWR CTLED ARPT AT OWN RISK DUE TO THE RWY BEING OFFICIALLY CLOSED AFTER SUNSET.

Narrative

RWY 26R/8L AT BROWN FIELD WAS NOTAMED CLOSED DUE TO CONSTRUCTION ON THE RWY. RWY 26L/8R; AN UNLIT RWY; WAS OPEN DURING THE DAY. ALL RWYS AND TXWYS WERE NOTAMED CLOSED FROM SUNSET TO SUNRISE. I ASSUMED THAT RWY 26L/8R WAS CLOSED AFTER SUNSET SINCE IT WAS UNLIT SO I ASKED BROWN TWR EARLIER IN THE DAY WHEN I LANDED ON MY WAY TO MEXICO IF I COULD USE RWY 26L/8R WITHIN THE 30 MINS AFTER SUNSET SINCE AFTER 30 MINS IS THE TIME WHEN NIGHT FLT BEGINS. THE TWR RESPONDED THAT THEY COULD NOT ISSUE CLRNCS FOR LNDG OR TAKING OFF AFTER OFFICIAL SUNSET OFF BUT THAT I COULD USE THE RWY AT MY OWN RISK. I ASKED FOR OFFICIAL SUNSET AND WAS TOLD XA53. ON MY RETURN FROM MEXICO; I CALLED BROWN TWR AT XA55 AFTER A HDOF FROM TIJUANA TWR AND THE CTLR INFORMED ME THAT THE ARPT WAS CLOSED AND ASKED ME TO STATE MY INTENTIONS. I INFORMED THE CTLR THAT I WAS UNDER THE IMPRESSION THAT I COULD USE RWY 26L/8R AT MY OWN RISK. THE CTLR DID NOT RESPOND IMMEDIATELY BUT CAME BACK ON THE RADIO AFTER A SHORT WHILE AS IF HE HAD CONFERRED WITH OTHER CTLRS IN THE TWR AND SAID 'PROCEED AT YOUR OWN RISK.' I ANNOUNCED MY INTENTIONS IN THE BLIND ON THE CTAF; LANDED; CLRED CUSTOMS AND DEPARTED AT XB06. ON ALL PHASES OF THE LNDG; TAXIING AND TKOF; I HAD EXCELLENT VISIBILITY AND DID NOT BELIEVE THAT I WAS ACTING IN AN UNSAFE MANNER. AFTER REACHING MY DEST; I CONFERRED WITH SOME FRIENDS ABOUT WHAT HAD TRANSPIRED AND THEY BELIEVED THAT I WAS NOT LEGALLY ALLOWED TO LAND SINCE THE ARPT WAS NOTAMED CLOSED. I CAN SEE THEIR POINT SO I HAVE FILED THIS RPT IN HOPES THAT PLTS COULD BE BETTER EDUCATED AS TO HOW TO PROCEED IN THIS TYPE OF SIT.
