Narrative:

Departed runway 15 hya straight out towards ack; level at 1000 ft. An aircraft called tower south of hya for landing; was instructed to report left base for runway 24. A second aircraft reported south of hya and was also instructed to report left base for runway 24. The second pilot then requested straight in runway 33 and was granted permission. The first aircraft's pilot then also requested straight to runway 33 and was granted permission. I was advised of traffic 12 o'clock; 2 miles; aircraft at 1500 ft. I saw traffic; the first airplane; and acknowledged traffic in sight. The first aircraft's pilot was advised traffic 12 o'clock; 2 miles; 1000 ft (me). The pilot acknowledged traffic in sight and then descended to my altitude directly in front of me. In order to avoid a midair collision I had to turn using 40 degrees of bank. When we passed each other we were at the same altitude going in opposite direction approximately 400 ft apart.
