Narrative:

It was a VFR day flight and I flew with my student to casa grande/stanfield VOR to practice instrument approachs. We entered holding over stanfield VOR at 4500 ft and after a few rounds in holding I pulled an engine on my student and instructed him to feather it. After another couple of rounds in the hold (single engine) I told him he was cleared ILS runway 5 approach and instructed him to restart and set us up for 0 thrust. The engine would not restart and we decided to go ahead and shoot the ILS approach and do full stop landing at casa grande to check problem. I reported on local unicom to the traffic that we were inbound on the ILS practice approach, I also reported VOR inbound and roxie inbound (which is 4 mi final). When we were on 1 mi final and I was just about to report so, someone reported base to final runway 5. I turned my head to the left and saw a yellow tail dragger (type unknown) turning from downwind to base. Because of our engine being feathered, I called as follows: airplane on base at casa grande, this is small aircraft twin engine aircraft, we're on 3/4 mi final, would you mind letting us go first we have one engine out. The person in the other airplane answered: you guys go ahead, if you have an emergency. But even as he was saying this he made no attempt to change course and was approaching us very fast. I told my student to break right which we did, and we afterwards lined up again to the runway and landed with no incident. When rolling down the runway I turned to see if the other airplane was doing a 360, but he was already on the runway behind us, rolling out. We taxied off the runway, pulled over to a runup area to attempt to find problem with engine. Meanwhile the pilot of the other airplane is asking lots of questions about the safety of feathering an engine in an small aircraft twin and he said he would call us on the phone, which he never did. I called him on the radio and politely thanked him for his help and said I was sorry I did not know he was there until he called. My biggest problem with this incident is the other pilots attitude. You would think that the natural thing to do is to help a fellow pilot not try to nail him for something. When we saw him we were also lower than him on our approach. I did not mean to cut in front of him and if we had had both engines we would have gone around immediately.

Title: NMAC BTWN AN SMA TWIN ENG ACFT ON PRACTICE ILS APCH TO UNCTLED ARPT AND AN SMA ACFT IN THE ATA.

Narrative: IT WAS A VFR DAY FLT AND I FLEW WITH MY STUDENT TO CASA GRANDE/STANFIELD VOR TO PRACTICE INST APCHS. WE ENTERED HOLDING OVER STANFIELD VOR AT 4500 FT AND AFTER A FEW ROUNDS IN HOLDING I PULLED AN ENG ON MY STUDENT AND INSTRUCTED HIM TO FEATHER IT. AFTER ANOTHER COUPLE OF ROUNDS IN THE HOLD (SINGLE ENG) I TOLD HIM HE WAS CLRED ILS RWY 5 APCH AND INSTRUCTED HIM TO RESTART AND SET US UP FOR 0 THRUST. THE ENG WOULD NOT RESTART AND WE DECIDED TO GO AHEAD AND SHOOT THE ILS APCH AND DO FULL STOP LNDG AT CASA GRANDE TO CHK PROBLEM. I RPTED ON LCL UNICOM TO THE TFC THAT WE WERE INBOUND ON THE ILS PRACTICE APCH, I ALSO RPTED VOR INBOUND AND ROXIE INBOUND (WHICH IS 4 MI FINAL). WHEN WE WERE ON 1 MI FINAL AND I WAS JUST ABOUT TO RPT SO, SOMEONE RPTED BASE TO FINAL RWY 5. I TURNED MY HEAD TO THE L AND SAW A YELLOW TAIL DRAGGER (TYPE UNKNOWN) TURNING FROM DOWNWIND TO BASE. BECAUSE OF OUR ENG BEING FEATHERED, I CALLED AS FOLLOWS: AIRPLANE ON BASE AT CASA GRANDE, THIS IS SMA TWIN ENG ACFT, WE'RE ON 3/4 MI FINAL, WOULD YOU MIND LETTING US GO FIRST WE HAVE ONE ENG OUT. THE PERSON IN THE OTHER AIRPLANE ANSWERED: YOU GUYS GO AHEAD, IF YOU HAVE AN EMER. BUT EVEN AS HE WAS SAYING THIS HE MADE NO ATTEMPT TO CHANGE COURSE AND WAS APCHING US VERY FAST. I TOLD MY STUDENT TO BREAK R WHICH WE DID, AND WE AFTERWARDS LINED UP AGAIN TO THE RWY AND LANDED WITH NO INCIDENT. WHEN ROLLING DOWN THE RWY I TURNED TO SEE IF THE OTHER AIRPLANE WAS DOING A 360, BUT HE WAS ALREADY ON THE RWY BEHIND US, ROLLING OUT. WE TAXIED OFF THE RWY, PULLED OVER TO A RUNUP AREA TO ATTEMPT TO FIND PROBLEM WITH ENG. MEANWHILE THE PLT OF THE OTHER AIRPLANE IS ASKING LOTS OF QUESTIONS ABOUT THE SAFETY OF FEATHERING AN ENG IN AN SMA TWIN AND HE SAID HE WOULD CALL US ON THE PHONE, WHICH HE NEVER DID. I CALLED HIM ON THE RADIO AND POLITELY THANKED HIM FOR HIS HELP AND SAID I WAS SORRY I DID NOT KNOW HE WAS THERE UNTIL HE CALLED. MY BIGGEST PROBLEM WITH THIS INCIDENT IS THE OTHER PLTS ATTITUDE. YOU WOULD THINK THAT THE NATURAL THING TO DO IS TO HELP A FELLOW PLT NOT TRY TO NAIL HIM FOR SOMETHING. WHEN WE SAW HIM WE WERE ALSO LOWER THAN HIM ON OUR APCH. I DID NOT MEAN TO CUT IN FRONT OF HIM AND IF WE HAD HAD BOTH ENGS WE WOULD HAVE GONE AROUND IMMEDIATELY.
