Narrative:

After receiving my clearance down to 4000 ft I heard a falcon jet check-on with palm springs approach. The flacon had just departed udd and was climbing through 1300 ft requesting an IFR clearance. Approach's reply to the falcon was to stand-by for his clearance and maintain VFR. Approach then reported the falcon traffic to me, and although I was already trying to find the falcon, the haze and distance making it extremely difficult, I reported to psp approach negative contact. About 1 min later, psp approach called the falcon traffic to me again, I reported negative contact with the falcon and that I had udd in sight. A few moments later I established visual contact with the falcon at my 1 O'clock position. At that instant, it appeared that the falcon was climbing and would pass of my right side. I called palm springs approach and said traffic in sight no factor. Just as I finished my radio transmission to psp approach the falcon was in a climbing right turn coming directly at me. I initiated evasive action to avoid the falcon by maneuvering my aircraft into a steep diving right turn. Upon recovering from my evasive maneuver, I called psp approach and told them I had to maneuver to avoid the falcon.

Title: AN IFR BEECH-90 HAD A NEAR MISS WITH A VFR FALCON JET NEAR PSP.

Narrative: AFTER RECEIVING MY CLRNC DOWN TO 4000 FT I HEARD A FALCON JET CHK-ON WITH PALM SPRINGS APCH. THE FLACON HAD JUST DEPARTED UDD AND WAS CLBING THROUGH 1300 FT REQUESTING AN IFR CLRNC. APCH'S REPLY TO THE FALCON WAS TO STAND-BY FOR HIS CLRNC AND MAINTAIN VFR. APCH THEN RPTED THE FALCON TFC TO ME, AND ALTHOUGH I WAS ALREADY TRYING TO FIND THE FALCON, THE HAZE AND DISTANCE MAKING IT EXTREMELY DIFFICULT, I RPTED TO PSP APCH NEGATIVE CONTACT. ABOUT 1 MIN LATER, PSP APCH CALLED THE FALCON TFC TO ME AGAIN, I RPTED NEGATIVE CONTACT WITH THE FALCON AND THAT I HAD UDD IN SIGHT. A FEW MOMENTS LATER I ESTABLISHED VISUAL CONTACT WITH THE FALCON AT MY 1 O'CLOCK POS. AT THAT INSTANT, IT APPEARED THAT THE FALCON WAS CLBING AND WOULD PASS OF MY R SIDE. I CALLED PALM SPRINGS APCH AND SAID TFC IN SIGHT NO FACTOR. JUST AS I FINISHED MY RADIO XMISSION TO PSP APCH THE FALCON WAS IN A CLBING R TURN COMING DIRECTLY AT ME. I INITIATED EVASIVE ACTION TO AVOID THE FALCON BY MANEUVERING MY ACFT INTO A STEEP DIVING R TURN. UPON RECOVERING FROM MY EVASIVE MANEUVER, I CALLED PSP APCH AND TOLD THEM I HAD TO MANEUVER TO AVOID THE FALCON.
