Narrative:

My airplane was entering a 45 degree entry to runway 6 at evb. Small aircraft Y asked for an advisory and I told them runway 6. As we entered, I saw a plane on what appeared to be a 90 degree entry to runway 6. I made several radio calls to clarify my position. The plane (small aircraft Y) then turned right downwind to runway 24. I made several evasive maneuvers to avoid a collision. As I started a right turn, aircraft appeared to start a 180 degree turn to the right towards me. I made a steep dive to avoid. When the plane (small aircraft Y) finally broke off to the right, we were able to land with no further problems. Small aircraft Y finally entered correctly. The aircraft appeared to be based at evb where there is no right traffic. Small aircraft Y never made a radio call, except to announce a go around.

Narrative: MY AIRPLANE WAS ENTERING A 45 DEG ENTRY TO RWY 6 AT EVB. SMA Y ASKED FOR AN ADVISORY AND I TOLD THEM RWY 6. AS WE ENTERED, I SAW A PLANE ON WHAT APPEARED TO BE A 90 DEG ENTRY TO RWY 6. I MADE SEVERAL RADIO CALLS TO CLARIFY MY POS. THE PLANE (SMA Y) THEN TURNED R DOWNWIND TO RWY 24. I MADE SEVERAL EVASIVE MANEUVERS TO AVOID A COLLISION.
