Analysis

The plt of N621SR said that as he entered the pattern downwind he saw only one low wing acft which was just turning final for rwy 25. On short final the plt said he noticed the wing and cockpit of the other acft in his left side periphial vision one second prior to the collision. The plt of N80579 said that he entered the pattern behind a PA28 acft, and, as he turned final, he noticed that the speed difference between his acft and the PA28 was erroding the spacing to the point that he elected to do a 360 degre turn on final to allow the PA28 time to land. On short final the plt felt a violent jerk and then saw the Boeing prop chewing into his right wing. The plt of N621SR said he was monitoring the UNICOM, but did not make any position reports. The plt of N80579 said he made '5 or 6' position reports, including one during the 360 turn, but heard none from the Boeing.
