Numerous witnesses reported that, shortly after takeoff, the airplane entered a steep right turn, the nose dropped, and the airplane entered a spiraling descent in a near-vertical attitude. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The damage to the airplane and surveillance video were consistent with a near-vertical descent indicative of an aerodynamic stall. Based on the available information, it is likely that the pilot failed to maintain sufficient airspeed while maneuvering, which resulted in an exceedance of the airplane’s critical angle of attack and a subsequent aerodynamic stall.

On November 07, 2021, about 1402 Alaska standard time, an experimental, amateur-built 2+2 airplane, N540AK, sustained substantial damage when it was involved in an accident near Kodiak, Alaska. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot departed from Kodiak Municipal Airport (KDK), Kodiak, Alaska, destined for a remote off-airport landing site near Saltery Cove. A friend of the pilot reported that the purpose of the flight was to transport hunting gear to the remote location to establish a hunting camp. Numerous witnesses reported that, shortly after departure from KDK, the airplane entered a steep right turn, the nose dropped, and the airplane entered a spiraling descent in a near-vertical attitude. The airplane impacted a gravel road at an elevation of about 92 ft mean sea level. A surveillance camera captured the impact sequence and showed the airplane impact in a right-wing-low, near-vertical attitude. The airplane came to rest about 25 ft from the initial impact site in a heavily wooded area and sustained substantial damage to the fuselage, wings, and tail. A postaccident examination of the airframe and engine revealed no pre-accident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
