Narrative:

I was flying on pipeline patrol southeast past the west end of runway 27 at portage county airport at 600 ft AGL, which is approved by our operations manual. I had reported my intentions on the proper advisory frequency immediately after hearing another aircraft reported taking the runway. I advised I would be on the lookout for him. I watched the runway closely but suddenly he appeared at my 9 O'clock level. He was climbing and I dove down so we then had a comfortable separation. In the future I must pay a lot more attention to other aircraft, and not quite so much on the pipeline.
