Narrative:

While in cruise at 4500 ft MSL on a magnetic heading of 190 degrees, I observed a piper multi-engine aircraft climbing directly towards me from my 11 O'clock. I banked sharply to the right using full aileron and rudder and dove in order to avoid a mid-air collision. I was receiving radar service (VFR), had an assigned squawk code, and was in radar contact. The traffic was never called by ATC. When I reported the near collision to the controller working me, he replied 'roger, flight XXXX.' had I not been maintaining a scan, I would not be filing this report. Especially in single-pilot operations, it is important to maintain separation without depending on ATC when in the VFR environment. This incident occurred in a matter of seconds (3). What if I'd been tuning a radio frequency or looking at a chart? This incident emphasized to me the importance of keeping one's head out of the flight deck.

Title: NMAC BTWN A SMA SEL AND A SMT TWIN.

Narrative: WHILE IN CRUISE AT 4500 FT MSL ON A MAGNETIC HDG OF 190 DEGS, I OBSERVED A PIPER MULTI-ENG ACFT CLBING DIRECTLY TOWARDS ME FROM MY 11 O'CLOCK. I BANKED SHARPLY TO THE R USING FULL AILERON AND RUDDER AND DOVE IN ORDER TO AVOID A MID-AIR COLLISION. I WAS RECEIVING RADAR SVC (VFR), HAD AN ASSIGNED SQUAWK CODE, AND WAS IN RADAR CONTACT. THE TFC WAS NEVER CALLED BY ATC. WHEN I RPTED THE NEAR COLLISION TO THE CTLR WORKING ME, HE REPLIED 'ROGER, FLT XXXX.' HAD I NOT BEEN MAINTAINING A SCAN, I WOULD NOT BE FILING THIS RPT. ESPECIALLY IN SINGLE-PLT OPS, IT IS IMPORTANT TO MAINTAIN SEPARATION WITHOUT DEPENDING ON ATC WHEN IN THE VFR ENVIRONMENT. THIS INCIDENT OCCURRED IN A MATTER OF SECONDS (3). WHAT IF I'D BEEN TUNING A RADIO FREQ OR LOOKING AT A CHART? THIS INCIDENT EMPHASIZED TO ME THE IMPORTANCE OF KEEPING ONE'S HEAD OUT OF THE FLT DECK.
