Narrative:

While on approach to pabv, I entered 45 degrees to downwind 'swift.' used CTAF 123.0, called 45 degrees and downwind, landed. I was told that on downwind I passed 20 ft below a 'cub' that was in the pattern. I did not see the aircraft. It was all 'white' and the day was overcast. My view of him would have been with a 'snowy' mountain range background, and his relative position to me would have been stationary. He had no lights or beacon on at the time.
