Human Factors
I was flying with a student pilot; practicing simulated engine failure emergency procedures. Student selected Frazier Lake airport (1C9) as the landing point. We positioned the airplane directly towards 1C9 for runway 5 which is a grass runway. I scanned the area in front and right of us to make sure there was no other traffic nearby. We descended towards runway 5 and ended the practice by going around above runway 5 at about 800 ft AGL. The next day we received a phone call from another pilot who was operating in traffic pattern at 1C9 attempting to land on the hard surface taxiway parallel to runway 5. He told us that he saw us on final flying next to him only approximately 200 ft above. He made few radio calls trying to reach us but no response; because we were not on 1C9 CTAF at the time. What have caused this event was that the student was busy performing the maneuver; forgot to change frequency to 1C9 CTAF and announce our intention. I was too focused on the training but overlooked the safety aspect of the flight. The corrective action is I should have changed frequency to 1C9 CTAF and monitor it when the student decided to head over there.
C152 Instructor reported failure to utilize CTAF resulted in a NMAC on final.
