On August 7, 2022, about 1425 eastern daylight time a Diamond Aircraft DA-40, N723AG, sustained minor damage when it was involved in an accident at Samuels Field Airport (BRY), Bardstown, Kentucky. A passenger was fatally injured and the private pilot and additional passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, after about a one-hour pleasure flight with a passenger in the front seat and in the back seat, they decided to land at BRY so the two passengers could switch seats. As they approached the airport, light rain was developing. The pilot stated they were quickly going to change seats because of the rain and the large canopy style door: he wanted to keep the rain out of the cockpit. During the taxi to the ramp, the front seat passenger handed the rear seat passenger her purse and phone and asked her to place it on the rear seat in preparations for switching seats. The pilot stated that before starting the shutdown checklist he briefed both passengers that when they exited the airplane, they would walk around the back of the airplane and meet at the tail then come back around and to watch out for the propeller. The pilot turned the airplane around to face the taxiway then came to a stop. Shortly after parking, the pilot opened the canopy as the engine was still operating but commenced the shutdown procedures per the checklist. As he was shutting down the engine, the front passenger exited the cockpit. The front seat passenger got out of the cockpit onto the right wing and stepped off the front step where she proceeded to walk into the operating propeller before the engine could be shut off and was fatally injured. According to the rear seat passenger, it all transpired “so fast” and the pilot did not provide any briefing information regarding exiting the airplane after they landed. The airplane was a four-seat, low-wing cantilever monoplane made from composite materials. It had fixed tricycle landing gear and a T-tail. The front canopy opened forward and up with the hinge on the front and the aft seat door was in a gullwing configuration only on the left side. The right wing, which was designed to be entered and exited off the front had a fuselage-mounted step forward of the leading edge wing root that was about 5 ft from the propeller arc. According to Diamond Aircraft, a temporary revision to the airplane flight manual was generated in 2014. Under the Temporary Revision, Entering and Exiting the Airplane; Chapter 4A.3 Checklists for Normal Operating Procedures. It stated the following: CAUTION Before starting the engine and until the engine is shut down, the canopy must be closed and latched in position 1 or 2 (‘cooling gap’) and the door must be closed and latched. During engine operation it is prohibited to enter or exit the airplane.
