Procedure
During an approach for runway 03 I entered a left downwind via a 45 degree entry. I determined the runway in use via ASOS and other aircraft in the pattern. Just after making the self-announce transmission on CTAF; my passenger and I both observed a Beech Bonanza opposite direction and descending to pattern altitude; approaching head on. I applied strong forward pressure on the yoke to effect a rapid and immediate descent. We passed under the other aircraft by approximately 50 feet. No other transmissions were heard from the incident aircraft; however two other aircraft on the frequency in the same pattern did answer. As I observed the Bonanza begin a wide; climbing turn to enter the pattern behind us; and still heard no transmissions; I announced their positon for the other aircraft. As I was taxiing to the ramp; I made my last transmission for the other aircraft as I observed them touching down. They finally made a transmission stating; 'We are on the frequency; what is the problem?' I did not reply. My guess; is that the CTAF frequency is one that is not common (122.72); and may have not been known by the other aircraft. The other aircraft descending into the pattern did not make for scanning for traffic easy. It was pure luck that we missed one another.
A C150 pilot reported taking evasive action to prevent airborne conflict with an aircraft entering approach pattern to an uncontrolled airport and not communicating their intentions on CTAF.
