Key Takeaways:

  • The NTSB determined the fatal AT-6D Texan accident at EAA AirVenture 2023, which killed pilot Devyn Reiley and her passenger, was caused by an inadvertent aerodynamic stall/spin.
  • The aircraft entered a flat spin after its speed diminished during turns, with a calculated load factor reaching 1.8 G, consistent with an accelerated stall at approximately 87 mph (accelerated stall speed at that load factor was about 89 mph).
  • Pilot Devyn Reiley had 687.8 total flight hours, including 33 hours in the AT-6D, though her one-hour checkout flight log entry for the AT-6D did not specify maneuvers performed.
