Narrative:

I encountered a near miss situation with another airplane. I was downwind for runway 31 at st cloud, which I gave a radio call announcing that I am downwind for runway 31. I then prepared myself and the cockpit for the landing. As I approached abeam the numbers, I scanned the area southeast of runway 31 and did not see another aircraft. I also have not heard anyone else announce a position in the traffic pattern during the whole time that I had been in the traffic pattern. I gave a call that I was turning left base and started my descent. As I am on base to final, I again scanned the area southeast of runway 31 and did not see another airplane. I announced that I am turning final for runway 31 and proceeded my turn onto final when I heard a pilot from the ground call out 'do you guys see each other up there?' I looked out my left window and spotted an airplane about 300 ft below me heading for runway 31. I quickly responded by doing a go around and avoided the hazardous situation. I believe the problem was created from not communicating enough. I feel the other pilot should have announced position reports or more of them. I did not hear a word from the other aircraft from when I was mid downwind to when I was turning final. Shortly after the pilot on the ground expressed his concern, I did hear the aircraft that I encountered the near miss with, announce that they were going missed approach. My corrective action to prevent this occurrence from happening again is to extend my downwind a little more to give me extra time to scan the area and ask pilots to give position reports.

Title: A C172 PLT HAS AN NMAC WITH ANOTHER C172 WHILE LNDG AT AN UNCTLED FIELD.

Narrative: I ENCOUNTERED A NEAR MISS SIT WITH ANOTHER AIRPLANE. I WAS DOWNWIND FOR RWY 31 AT ST CLOUD, WHICH I GAVE A RADIO CALL ANNOUNCING THAT I AM DOWNWIND FOR RWY 31. I THEN PREPARED MYSELF AND THE COCKPIT FOR THE LNDG. AS I APCHED ABEAM THE NUMBERS, I SCANNED THE AREA SE OF RWY 31 AND DID NOT SEE ANOTHER ACFT. I ALSO HAVE NOT HEARD ANYONE ELSE ANNOUNCE A POS IN THE TFC PATTERN DURING THE WHOLE TIME THAT I HAD BEEN IN THE TFC PATTERN. I GAVE A CALL THAT I WAS TURNING L BASE AND STARTED MY DSCNT. AS I AM ON BASE TO FINAL, I AGAIN SCANNED THE AREA SE OF RWY 31 AND DID NOT SEE ANOTHER AIRPLANE. I ANNOUNCED THAT I AM TURNING FINAL FOR RWY 31 AND PROCEEDED MY TURN ONTO FINAL WHEN I HEARD A PLT FROM THE GND CALL OUT 'DO YOU GUYS SEE EACH OTHER UP THERE?' I LOOKED OUT MY L WINDOW AND SPOTTED AN AIRPLANE ABOUT 300 FT BELOW ME HDG FOR RWY 31. I QUICKLY RESPONDED BY DOING A GAR AND AVOIDED THE HAZARDOUS SIT. I BELIEVE THE PROB WAS CREATED FROM NOT COMMUNICATING ENOUGH. I FEEL THE OTHER PLT SHOULD HAVE ANNOUNCED POS RPTS OR MORE OF THEM. I DID NOT HEAR A WORD FROM THE OTHER ACFT FROM WHEN I WAS MID DOWNWIND TO WHEN I WAS TURNING FINAL. SHORTLY AFTER THE PLT ON THE GND EXPRESSED HIS CONCERN, I DID HEAR THE ACFT THAT I ENCOUNTERED THE NEAR MISS WITH, ANNOUNCE THAT THEY WERE GOING MISSED APCH. MY CORRECTIVE ACTION TO PREVENT THIS OCCURRENCE FROM HAPPENING AGAIN IS TO EXTEND MY DOWNWIND A LITTLE MORE TO GIVE ME EXTRA TIME TO SCAN THE AREA AND ASK PLTS TO GIVE POS RPTS.
