Narrative:

I was on an instrument flight plan cleared for the VOR-a approach into emt. I had passed kelog intersection. I was descending from 3500 ft to 2800 ft approaching azusa intersection. My safety pilot was sitting in the right front seat watching for traffic. I had a 'vision restricting' device on as I was under simulated IFR. The other aircraft, a beech bonanza, came up from behind and to my left below me. I had been turned over to emt tower at that time by ont approach, so I did not have any warning because emt does not have BRITE radar. I saw something move out of the corner of my left eye. What I saw was an aircraft about 100-150 ft below me, almost directly under me, but slightly to the left. I reported to emt tower that I had traffic, they said they did not have radar. The other aircraft continued its climb and crossed over my flight path. Since its speed was much greater, no evasive action was necessary. The pilot of the other aircraft called emt requesting east to west transition at 3000 ft through the class D airspace. Emt told him about me, he said I was behind him, so he saw me as he passed. Proposed solution -- emt should have BRITE radar to allow them to see targets on approach.

Original NASA ASRS Text

Title: 2 SMAS HAD AN NMAC ON THE INST APCH TRACK.

Narrative: I WAS ON AN INST FLT PLAN CLRED FOR THE VOR-A APCH INTO EMT. I HAD PASSED KELOG INTXN. I WAS DSNDING FROM 3500 FT TO 2800 FT APCHING AZUSA INTXN. MY SAFETY PLT WAS SITTING IN THE R FRONT SEAT WATCHING FOR TFC. I HAD A 'VISION RESTRICTING' DEVICE ON AS I WAS UNDER SIMULATED IFR. THE OTHER ACFT, A BEECH BONANZA, CAME UP FROM BEHIND AND TO MY L BELOW ME. I HAD BEEN TURNED OVER TO EMT TWR AT THAT TIME BY ONT APCH, SO I DID NOT HAVE ANY WARNING BECAUSE EMT DOES NOT HAVE BRITE RADAR. I SAW SOMETHING MOVE OUT OF THE CORNER OF MY L EYE. WHAT I SAW WAS AN ACFT ABOUT 100-150 FT BELOW ME, ALMOST DIRECTLY UNDER ME, BUT SLIGHTLY TO THE L. I RPTED TO EMT TWR THAT I HAD TFC, THEY SAID THEY DID NOT HAVE RADAR. THE OTHER ACFT CONTINUED ITS CLB AND CROSSED OVER MY FLT PATH. SINCE ITS SPD WAS MUCH GREATER, NO EVASIVE ACTION WAS NECESSARY. THE PLT OF THE OTHER ACFT CALLED EMT REQUESTING E TO W TRANSITION AT 3000 FT THROUGH THE CLASS D AIRSPACE. EMT TOLD HIM ABOUT ME, HE SAID I WAS BEHIND HIM, SO HE SAW ME AS HE PASSED. PROPOSED SOLUTION -- EMT SHOULD HAVE BRITE RADAR TO ALLOW THEM TO SEE TARGETS ON APCH.
