Narrative:

We were practicing ground reference maneuvers and experienced a near midair collision/conflict in the portion of the school's designated practice area that was closest to the airport. Ways we could have avoided the incident: 1) exercised greater vigilance in clearing the practice area, and 2) listening more closely to the radio. Inactions on the other aircraft's part: 1) lack of proper TA calls, 2) lack of situational awareness, since we had made several position reports stating our position, altitude, and intentions.

Title: C172 MANEUVERING IN PRACTICE AREA EXPERIENCES NMAC.

Narrative: WE WERE PRACTICING GND REF MANEUVERS AND EXPERIENCED A NMAC/CONFLICT IN THE PORTION OF THE SCHOOL'S DESIGNATED PRACTICE AREA THAT WAS CLOSEST TO THE ARPT. WAYS WE COULD HAVE AVOIDED THE INCIDENT: 1) EXERCISED GREATER VIGILANCE IN CLRING THE PRACTICE AREA, AND 2) LISTENING MORE CLOSELY TO THE RADIO. INACTIONS ON THE OTHER ACFT'S PART: 1) LACK OF PROPER TA CALLS, 2) LACK OF SITUATIONAL AWARENESS, SINCE WE HAD MADE SEVERAL POS RPTS STATING OUR POS, ALT, AND INTENTIONS.
