AN A300 ACR ACFT PREPARING FOR APCH TO FOREIGN ARPT FLC CLRED TO INTERCEPT VOR RADIAL INBOUND; BUT FLC NOTAM SHOWED THE VOR OTS. WHEN QUESTIONING APCH CTLR ABOUT VOR STATUS HE WOULD NOT COMMIT; BUT AN IDENT WAS RECEIVED ON THE VOR AND IT APPEARED TO BE NORMAL SO FLC USED IT. LATER THEY REALIZED THAT IF THE VOR WAS DOWN THEY WERE IN THE VICINITY OF HIGH HILLS AND AT NIGHT; SO THEY SHOULD HAVE BEEN MORE DILIGENT IN GETTING THE VOR STATUS.

Narrative

CLRED TO INTERCEPT AND TRACK INBOUND A RADIAL TO MIQ VOR. WE RESPONDED THAT OUR NOTAMS SHOWED MIQ OTS. AGAIN A SIMILAR CLRNC WAS GIVEN. THE VOR TUNED AND IDENTED; WE CONTINUED IN USING THE VOR AND MADE AN ILS TO RWY 9 WHICH REQUIRES MIQ VOR. AFTER UNEVENTFUL APCH AND LNDG; I REGRET NOT PRESSING FOR CONFIRMATION MORE FORCEFULLY FROM TWR ON STATUS OF MIQ VOR. IT WAS NIGHT AND NEAR HILLS AND VOR MAY INDEED HAVE BEEN OTS EVEN THOUGH IT WAS PROPERLY IDENTED. SUPPLEMENTAL INFO FROM ACN 384022: APCH PLATE INSTRUCTIONS DICTATED USE OF VOR RADIAL. MIQ APCH WOULD NOT COMMIT WHEN ASKED IF VOR WAS OPERABLE. RECEIVED RADAR VECTORS TO LOC. WE PAINTED THE SHORELINE WITH RADAR AND HAD A GOOD IDENT ON THE BEACON. LNDG WAS UNEVENTFUL. PAPERWORK FOR THE TRIP OUT THE NEXT DAY INDICATED VOR IN SVC (NO NOTAMS OR SPECIAL MESSAGE); BUT A DIFFERENT SPECIAL MESSAGE STATED FMS ACFT DID NOT REQUIRE VOR FOR ILS RWY 9. BESIDES LEGALITY CONCERNS; A FALSE LOC N OF THE ILS AND MOUNTAINOUS TERRAIN CAUSED US TO DESIRE RAW DATA VERIFICATION OF POS.
