Analysis

After landing at the airport, the passenger seated in the left seat of the Cessna 172 exited the airplane to notify restaurant staff of her arrival. As she walked toward the front of the airplane, the passenger stated she did not see the rotating propeller and "walked into it." In a statement taken by local police immediately following the accident, the pilot reported he asked the passenger to get out of the airplane and go into the restaurant to find out where the airplane could be parked. In a subsequent written statement provided to the Safety Board, the pilot stated the passenger exited the airplane without his knowledge, while he was shutting down the engine. The passenger was not available to answer subsequent questions regarding what, if any, briefing was given to the passenger by the pilot, pertaining to procedures for exiting the airplane. During an interview, the pilot stated that prior to the flight he had not briefed the passenger on procedures for exiting the airplane.
