Narrative:

[I was in] uncontrolled airspace; in traffic pattern; training a student; landing lights on. I was in the traffic pattern using proper radio technique flying from left crosswind to downwind when bonanza called in 'ten miles north landing at airport.' I announced my position at just entering left downwind. Bonanza kept asking where I was in downwind. Three times I reported where I was. [I] never got a response from my answers to his requests. When I was 50 feet from midfield left downwind the bonanza 'diving in front of me' from directly over the airport higher than the recommended traffic pattern and missed me by 50 feet. Summary: no entry over the airport should be emphasized from any transition point on uncontrolled airports. All pilots should follow the aim recommendations for entry into the traffic patterns. There are the potential safety issues as gliders; sky divers; helicopters; are also using these uncontrolled facilities. In my instance this bonanza pilot was at the wrong traffic pattern altitude and entered the pattern outside the recommended procedure as written in the aim. This happened because of the cavalier attitude that some pilots have regarding the traffic pattern rules from the good ole days. Keep the rules as written in the aim and emphasize the problem with diving into the traffic pattern especially while aircraft are in the pattern.
