General Aviation pilot reported the need to take evasive action while on base leg to TRM Airport to avoid a jet that had not been communicating on CTAF. The reporter stated this airport is very busy with a mix of jets and small general aviation aircraft.

Narrative

This airport is literally a major accident waiting to happen!!! This airport needs a tower asap or lives will be lost!!! This happens nearly every time I have been flying from October to June which is the 'season' here in the Palm Springs area. There is so much traffic in the area from small General Aviation aircraft to very large corporate aircraft up to B757s and a G7 the other day and even though some pilots like me follow the uncontrolled airport rules many do not. On the day noted here; there were 7 large planes in the pattern flying both left and right traffic; there were 7 large planes waiting to take off IFR. The other day we were flying the pattern on right base with 3 other planes behind us and a Challenger who had not said a word says on base turning to final! We had to abort and make a quick 360 to not run into him. Part of the problem is all these corporate jets and others who are IFR are talking to SoCal Approach and then get handed off within 5 miles of the airport moving fast and come up on everyone else in the pattern VERY quickly! What does it take to get a Tower before and accident happens soon?
