Narrative:

I was on a 230 degree radar vector heading approximately 10 mi e-ne of mkc airport. I was given a descent from 4000 ft to 3000 ft. At the time of start of descent, I looked out my left wing and saw wingtip red and green navigation lights. They were immediately behind my wing same direction, maybe a 25 degree heading difference. I could tell it was a small single-engine piper -- probably a cherokee. I passed within 20 seconds. Then I called approach who had no radar contact before or during. Not until after he passed did they get a primary only target. That's when I informed approach of the near- miss. The main problem I think was that the other plane did not have his transponder on, which he was supposed to in the 30 mi area of the class B, which he was.

Original NASA ASRS Text

Title: CPR LTT HAD A CLOSE NMAC WITH A SMA, PROBABLY A PA28.

Narrative: I WAS ON A 230 DEG RADAR VECTOR HEADING APPROX 10 MI E-NE OF MKC ARPT. I WAS GIVEN A DSCNT FROM 4000 FT TO 3000 FT. AT THE TIME OF START OF DSCNT, I LOOKED OUT MY L WING AND SAW WINGTIP RED AND GREEN NAV LIGHTS. THEY WERE IMMEDIATELY BEHIND MY WING SAME DIRECTION, MAYBE A 25 DEG HDG DIFFERENCE. I COULD TELL IT WAS A SMALL SINGLE-ENG PIPER -- PROBABLY A CHEROKEE. I PASSED WITHIN 20 SECONDS. THEN I CALLED APCH WHO HAD NO RADAR CONTACT BEFORE OR DURING. NOT UNTIL AFTER HE PASSED DID THEY GET A PRIMARY ONLY TARGET. THAT'S WHEN I INFORMED APCH OF THE NEAR- MISS. THE MAIN PROB I THINK WAS THAT THE OTHER PLANE DID NOT HAVE HIS XPONDER ON, WHICH HE WAS SUPPOSED TO IN THE 30 MI AREA OF THE CLASS B, WHICH HE WAS.
