Narrative:

Flight was from buenos aires to santiago. After navigating the appropriate STAR, I joined the localizer and reported 'runway in sight' to my crew (not the controller since this was our first time to santiago -- all of us). The approach controller, who was obviously also the local controller, said 'cleared to land runway 17R'. My approach plate showed only one runway 17. Now I am wondering if I have the right airport. All through final approach I questioned the controller as to the name of the airport, confirm runway 17R, etc. The only response was 'cleared to land runway 17R.' everything matched up so I landed. The problem: often at night, for maintenance purposes, the chileans close the main runway 17 and light a parallel taxiway for operations. The taxiway is concrete, 150 ft wide and has runway lighting. Perfectly safe. But, they won't tell you and it is not notamed. I think crews operating into santiago should be aware of this possibility so they don't go crazy like I did.

Title: AN ACR HVT FRTR LANDED ON RWY 17R AT SCEL. THERE IS ONLY ONE RWY, BUT A TXWY CAN BE USED FOR LNDG.

Narrative: FLT WAS FROM BUENOS AIRES TO SANTIAGO. AFTER NAVING THE APPROPRIATE STAR, I JOINED THE LOC AND RPTED 'RWY IN SIGHT' TO MY CREW (NOT THE CTLR SINCE THIS WAS OUR FIRST TIME TO SANTIAGO -- ALL OF US). THE APCH CTLR, WHO WAS OBVIOUSLY ALSO THE LCL CTLR, SAID 'CLRED TO LAND RWY 17R'. MY APCH PLATE SHOWED ONLY ONE RWY 17. NOW I AM WONDERING IF I HAVE THE RIGHT ARPT. ALL THROUGH FINAL APCH I QUESTIONED THE CTLR AS TO THE NAME OF THE ARPT, CONFIRM RWY 17R, ETC. THE ONLY RESPONSE WAS 'CLRED TO LAND RWY 17R.' EVERYTHING MATCHED UP SO I LANDED. THE PROB: OFTEN AT NIGHT, FOR MAINT PURPOSES, THE CHILEANS CLOSE THE MAIN RWY 17 AND LIGHT A PARALLEL TXWY FOR OPS. THE TXWY IS CONCRETE, 150 FT WIDE AND HAS RWY LIGHTING. PERFECTLY SAFE. BUT, THEY WON'T TELL YOU AND IT IS NOT NOTAMED. I THINK CREWS OPERATING INTO SANTIAGO SHOULD BE AWARE OF THIS POSSIBILITY SO THEY DON'T GO CRAZY LIKE I DID.
