Narrative:

I was in a cruise climb after departing the palmer; ak; airport. This flight concluded a 2 day aerial/visual survey. We had flown about 4.5 hours of survey during the day at about 500-1000 ft AGL. My right front seat crew member/observer called out traffic. I asked for a position and he told me off the right. I did not immediately see the reported traffic so I banked the airplane to the left. Once I entered the left turn I saw the airplane appear from behind the right front door post. The airplane was about 1200 ft away and converging on our track. The high wing piper PA11/12/18 style airplane passed behind and slightly below our aircraft. I don't think the piper saw our aircraft until he was within about 120 ft away. The piper appeared to descend slightly from the first position that I saw him since he was at our same altitude when I first saw the airplane. A midair collision occurred near this location less than 2 yrs ago. I normally transit this geographical area above 2500 ft in order to be above the local traffic. There is a very high density of private airstrips within 5 mi of the location of this near miss event.

Title: A CESSNA CLIMBING OUT OF PAQ HAD AN NMAC WITH A PIPER.

Narrative: I WAS IN A CRUISE CLB AFTER DEPARTING THE PALMER; AK; ARPT. THIS FLT CONCLUDED A 2 DAY AERIAL/VISUAL SURVEY. WE HAD FLOWN ABOUT 4.5 HRS OF SURVEY DURING THE DAY AT ABOUT 500-1000 FT AGL. MY R FRONT SEAT CREW MEMBER/OBSERVER CALLED OUT TFC. I ASKED FOR A POS AND HE TOLD ME OFF THE R. I DID NOT IMMEDIATELY SEE THE RPTED TFC SO I BANKED THE AIRPLANE TO THE L. ONCE I ENTERED THE L TURN I SAW THE AIRPLANE APPEAR FROM BEHIND THE R FRONT DOOR POST. THE AIRPLANE WAS ABOUT 1200 FT AWAY AND CONVERGING ON OUR TRACK. THE HIGH WING PIPER PA11/12/18 STYLE AIRPLANE PASSED BEHIND AND SLIGHTLY BELOW OUR ACFT. I DON'T THINK THE PIPER SAW OUR ACFT UNTIL HE WAS WITHIN ABOUT 120 FT AWAY. THE PIPER APPEARED TO DSND SLIGHTLY FROM THE FIRST POS THAT I SAW HIM SINCE HE WAS AT OUR SAME ALT WHEN I FIRST SAW THE AIRPLANE. A MIDAIR COLLISION OCCURRED NEAR THIS LOCATION LESS THAN 2 YRS AGO. I NORMALLY TRANSIT THIS GEOGRAPHICAL AREA ABOVE 2500 FT IN ORDER TO BE ABOVE THE LCL TFC. THERE IS A VERY HIGH DENSITY OF PVT AIRSTRIPS WITHIN 5 MI OF THE LOCATION OF THIS NEAR MISS EVENT.
