C152 PLT IN PATTERN MADE CALLS ON UNICOM AND ON FINAL SAW ANOTHER ACFT WHICH HAD CUT RPTR OUT WITHOUT ANY RADIO CALLS. RPTR DID GAR AND CONFRONTED OTHER PLT ON THE GND.

Narrative

I WAS IN THE PATTERN OF OCEANSIDE ARPT PRACTICING TKOFS AND LNDGS ON RWY 24. I CALLED OUT XWIND; DOWNWIND; BASE AND FINAL. AS I WAS COMING OUT OF MY FINAL TURN FOR RWY 24 I OBSERVED A MOONEY ON FINAL ABOUT 500-1000 FT IN FRONT OF ME AND 100-200 FT BELOW. OCEANSIDE HAS A NOISE ABATEMENT POLICY AND STRAIGHT-INS ARE PROHIBITED. I HEARD NO ACFT RPT A STRAIGHT-IN APCH. I WAS FORCED TO DO A GAR. I CALLED THE MOONEY THAT WAS NOW ON THE RWY AS I CLBED OUT FOR THE GAR I ASKED 'WHERE DID YOU COME FROM?' AND THE UNICOM OPERATOR CALLED THE MOONEY TO FIND OUT WHAT HAPPENED. THE MOONEY DID NOT REPLY TO EITHER REQUESTS. I CAME AROUND; LANDED; TIED DOWN AND CONFRONTED THE MOONEY PLT THAT WAS NOW BACK IN HIS ACFT AND READY TO DEPART. I ASKED HIM IF HE FLEW A STRAIGHT-IN APCH; HE SAID YES. ASKED IF HE ANNOUNCED HIS INTENTIONS; HE THOUGHT HE DID. ASKED IF HE HEARD MY XMISSION IN THE PATTERN; NO. DID HE SEE MY ACFT; NO. IN MY VIEW THE MOONEY PLT: A) DSNDED TO DO A STRAIGHT-IN APCH; DID NOT XMIT HIS INTENTIONS OR POS ON UNICOM; SAW MY ACFT ON BASE; KNEW HE COULD GET AHEAD OF ME ON FINAL; KNEW IT WOULD FORCE ME TO DO A GAR; DID NOT CARE. OR B) DID NOT XMIT INTENTION OR POS; DID NOT SEE ME; IGNORED MY RADIO REQUESTS; DID NOT CARE. I DON'T KNOW WHAT CAN BE DONE OTHER THAN THE FAA CONTACTING THE PLT OF THE MOONEY ABOUT THE INCIDENT AND REQUIRE ADDITIONAL TRAINING REQUIRING OPS AT A NON-CTLED FIELD.
