RPTR ON CHK FLT LANDS AT ARPT WITHOUT CLRNC.

Narrative

TO THIS DAY I STILL DON'T KNOW IF THERE WAS AN INCURSION OR VIOLATION. I AM NOT FROM THE DAYTON AREA. DURING MY 10 HRS OF MULTI ENG TRAINING I HAD BECOME AWARE THAT THE HRS AT WILLMINGTON AIRBORN AND SPRINGFIELD ARE IRREGULAR. CONSEQUENTLY; DURING MY WX BRIEFING WITH DAYTON FSS STATION I SPECIFICALLY ASKED ABOUT LCL NOTAMS ON THESE 2 ARPTS TFC AREAS. MY BRIEFER ADVISED THAT NEITHER TWR WAS GOING TO BE OPERATIONAL DURING MY FLYING TIMES - XA00 TO XE00 LCL TIME. DURING MY FLT TEST FOR MULTI ENG RATING; I WAS UNDER THE HOOD; HAD 1 ENG FEATHERED; AND WAS BEING VECTORED FOR THE APCH TO AIRBORNE RWY 4 BY DAYTON APCH. AT THIS TIME I ASKED FOR A LOW APCH. WHEN TURNED OVER TO CTAF I CALLED AND ADVISED THEM ON LOW APCH FOR RWY 4. THEY ANSWERED SOMETHING SO GARBLED IT WAS UNREADABLE LIKE SOMEONE WAS USING A HAND HELD. WE ASKED FOR THEM TO REPEAT; MEANWHILE THE ILS GAVE US AN OFF FLAG. THEY THEN ADVISED THEY HAD NO WAY OF MONITORING THE ILS. THE EXAMINER THEN ASKED IF THE TWR WAS OPERATING. NO ANSWER. THE EXAMINER THEN ASKED ME TO MAKE A FULL STOP LNDG WITH ONLY 1 ENG OPERATIONAL. WHICH I DID. THEY THEN SAID WE DID NOT HAVE PERMISSION TO LAND. SO WE ASK AGAIN IF THE TWR WAS OPERATIONAL? THEY AGAIN ANSWERED; SO GARBLED IT WAS UNINTELLIGIBLE. WE THEN CONTINUED TO OUR ORIGINAL DEST. AT THE TIME OF OUR LNDG THERE WERE NO X'S ON THE RWY. IF THE TWR WAS OPERATIONAL; THEY WERE HAVING PROBS WITH THEIR XMISSIONS. IF IT WAS NOT OPERATING; THEN THERE SHOULD BE SOME CTL OVER WHO IS OPERATING CTAF. I UNDERSTAND THIS A PROB AT THIS PARTICULAR ARPT AND SHOULD BE INVESTIGATED FOR SAFETY'S SAKE.
