On ILS 35R to low approach, G/south indications was erratic (ATIS report indicated ILS localizer was being worked on but received it correctly). No flag displayed on HSI for either localizer-G/south malfunction. Student attempted to follow G/south and arrived over airport at 8000' MSL. No report received by tower at OM inbound. Reported to tower over airport and they advised of missed approach procedure. Should be as published. Changed to approach for another ILS 35R at apa which was flown correctly. Callback conversation with reporter revealed the following: ATC did clear them for the ILS approach even though the ATIS said the ILS was being worked on. They did not get any indication of the LOM on the first approach but did on the second. He couldn't remember if they got the LMM. He says that the ILS has been shut down for the past few days for work, so there apparently was something wrong with it on the day of his report.
Original NASA ASRS Text
Title: DURING TRAINING FLT, STUDENT FLEW APCH AND MISSED APCH IMPROPERLY.
Narrative: ON ILS 35R TO LOW APCH, G/S INDICATIONS WAS ERRATIC (ATIS RPT INDICATED ILS LOC WAS BEING WORKED ON BUT RECEIVED IT CORRECTLY). NO FLAG DISPLAYED ON HSI FOR EITHER LOC-G/S MALFUNCTION. STUDENT ATTEMPTED TO FOLLOW G/S AND ARRIVED OVER ARPT AT 8000' MSL. NO RPT RECEIVED BY TWR AT OM INBND. RPTED TO TWR OVER ARPT AND THEY ADVISED OF MISSED APCH PROC. SHOULD BE AS PUBLISHED. CHANGED TO APCH FOR ANOTHER ILS 35R AT APA WHICH WAS FLOWN CORRECTLY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ATC DID CLR THEM FOR THE ILS APCH EVEN THOUGH THE ATIS SAID THE ILS WAS BEING WORKED ON. THEY DID NOT GET ANY INDICATION OF THE LOM ON THE FIRST APCH BUT DID ON THE SECOND. HE COULDN'T REMEMBER IF THEY GOT THE LMM. HE SAYS THAT THE ILS HAS BEEN SHUT DOWN FOR THE PAST FEW DAYS FOR WORK, SO THERE APPARENTLY WAS SOMETHING WRONG WITH IT ON THE DAY OF HIS RPT.
