On April 20, 1994, at 1550 Pacific daylight time, an individual was struck by the propeller of a Cessna 152, N159BC, that was standing on the ramp at the Auburn Airport, Auburn, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was not damaged and the commercial pilot was not injured. The individual sustained serious injuries to her left arm and shoulder. The pilot reported that this individual met him at the airport to deliver a letter to him. The individual approached the airplane from the right side and opened the door. At the conclusion of their conversation, the pilot instructed the individual to walk straight out to the wing tip and remain clear of the propeller. The individual instead, walked out around the right wing strut, then forward and was struck by the moving propeller.
