Narrative:

Departed home airport ona on IFR flight. Departure WX conditions VFR. FSS informed us ona VOR OTS but we had full letter identifier study signal solid instrument indications on departure along outbnd course to VOR 29 approach. Looked good to us therefore felt VOR was on line only maintenance had not called on correction. On return flight VOR approach to 29 at ona required VOR identify on, AWOS on steady solid navigation indications. ATC told us again VOR OTS. We relayed the above information and shot approach to just above minimums and landed. Subsequent telephone conversation with FSS personnel indicated that identify on a navigation aid does not mean it is in service. We thought that it did. Out deduction was from aim chapter #1 paragraph 16. Further research by us not in progress. Note: approach looked absolutely normal to us, both on instruments and when we broke out. Callback conversation with reporter revealed the following information. Reporter claims home field advantage, claiming that non-removal of the out of service NOTAM was an administrative error. Upon the rptrs return to ona, the ARTCC controller asked if the reporter was aware the NAVAID was notamed out of service. The reporter replied in affirmative, but indicated he was receiving a clear identifier. The controller then asked if the CDI needle indication appeared solid. Again the reporter replied in the affirmative. The center controller then rptedly cleared the reporter for an approach.

Title: ATX PLT FLYS APCH ON NAVAID NOTAMED OUT OF SERVICE.

Narrative: DEPARTED HOME ARPT ONA ON IFR FLT. DEP WX CONDITIONS VFR. FSS INFORMED US ONA VOR OTS BUT WE HAD FULL LETTER IDENTIFIER STUDY SIGNAL SOLID INSTRUMENT INDICATIONS ON DEP ALONG OUTBND COURSE TO VOR 29 APCH. LOOKED GOOD TO US THEREFORE FELT VOR WAS ON LINE ONLY MAINT HAD NOT CALLED ON CORRECTION. ON RETURN FLT VOR APCH TO 29 AT ONA REQUIRED VOR IDENT ON, AWOS ON STEADY SOLID NAV INDICATIONS. ATC TOLD US AGAIN VOR OTS. WE RELAYED THE ABOVE INFO AND SHOT APCH TO JUST ABOVE MINIMUMS AND LANDED. SUBSEQUENT TELEPHONE CONVERSATION WITH FSS PERSONNEL INDICATED THAT IDENT ON A NAV AID DOES NOT MEAN IT IS IN SVC. WE THOUGHT THAT IT DID. OUT DEDUCTION WAS FROM AIM CHAPTER #1 PARAGRAPH 16. FURTHER RESEARCH BY US NOT IN PROGRESS. NOTE: APCH LOOKED ABSOLUTELY NORMAL TO US, BOTH ON INSTRUMENTS AND WHEN WE BROKE OUT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR CLAIMS HOME FIELD ADVANTAGE, CLAIMING THAT NON-REMOVAL OF THE OUT OF SVC NOTAM WAS AN ADMINISTRATIVE ERROR. UPON THE RPTRS RETURN TO ONA, THE ARTCC CTLR ASKED IF THE RPTR WAS AWARE THE NAVAID WAS NOTAMED OUT OF SVC. THE RPTR REPLIED IN AFFIRMATIVE, BUT INDICATED HE WAS RECEIVING A CLR IDENTIFIER. THE CTLR THEN ASKED IF THE CDI NEEDLE INDICATION APPEARED SOLID. AGAIN THE RPTR REPLIED IN THE AFFIRMATIVE. THE CTR CTLR THEN RPTEDLY CLRED THE RPTR FOR AN APCH.
