Air carrier X departed runway 21 at the eugene airport, climbing to 9000'. Departure controller observed a VFR coded target flying from south to north approximately four mi southwest of the eugene airport. This aircraft was not in communication with ATC and was not displaying mode C altitude information. Traffic was issued to air carrier X and a right turn to the north was given. Shortly thereafter, the pilot of the air carrier X stated that the traffic was a yellow and white small aircraft Y and passed off his left wing about 40', same altitude. At that time the mode C on the air carrier X was changing from 3800' to 4000'. This type of incident is a continuing problem at facs/airports where communication with and/or control by ATC is not mandatory.
Original NASA ASRS Text
Title: ACR X HAD NMAC WITH VFR SMA Y.
Narrative: ACR X DEPARTED RWY 21 AT THE EUGENE ARPT, CLBING TO 9000'. DEP CTLR OBSERVED A VFR CODED TARGET FLYING FROM S TO N APPROX FOUR MI SW OF THE EUGENE ARPT. THIS ACFT WAS NOT IN COM WITH ATC AND WAS NOT DISPLAYING MODE C ALT INFO. TFC WAS ISSUED TO ACR X AND A R TURN TO THE N WAS GIVEN. SHORTLY THEREAFTER, THE PLT OF THE ACR X STATED THAT THE TFC WAS A YELLOW AND WHITE SMA Y AND PASSED OFF HIS L WING ABOUT 40', SAME ALT. AT THAT TIME THE MODE C ON THE ACR X WAS CHANGING FROM 3800' TO 4000'. THIS TYPE OF INCIDENT IS A CONTINUING PROB AT FACS/ARPTS WHERE COM WITH AND/OR CTL BY ATC IS NOT MANDATORY.
