Incident Overview
During a late-night preflight, a pilot started the aircraft's engine and advanced the throttle to move the airplane forward. The pilot felt an obstacle stopping the airplane and requested a friend standing nearby to inspect for any obstruction. The friend checked and reported that nothing was holding the aircraft back.
The Accident
As the friend turned to walk away, the rotating propeller struck and severed her right arm. The following morning, airport personnel discovered that the left wing and tail sections were not secured by their respective tie-down chains. However, the right wing tie-down chain remained fastened to the right wing.
