NTSB summary
On September 23, 2024, about 1357 central daylight time, an Aviat Aircraft Inc. S-1-11B airplane, N5111B, was substantially damaged when it was involved in an accident near Chapmansboro, Tennessee. The commercial pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot’s spouse, the pilot was flying that day to practice aerobatic routines in preparation for seeking a qualification to fly in airshow performances. According to FAA ADS-B flight track data, the airplane departed to the southeast from Whifferdill Airport (TN77), Chapmansboro, Tennessee, about 1345. The flight track showed that, after overflying the airport twice, the airplane spent the remainder of the flight about one mile south of the airport in the waivered aerobatic practice box performing low-altitude maneuvers between 400 and 2,000 ft agl. The final ADS-B flight track data point was recorded 12 minutes after takeoff, at 1357. According to a witness who was on a kayak on the Cumberland River about one half mile south of the accident site, the airplane had been performing a variety of aerobatic maneuvers at low altitude. He described that the airplane’s engine sound would go quiet and then “rev” back up during the maneuvering. He recorded several videos of the airplane as it flew, including a video that was about two minutes long that captured the final moments of the flight. In the last few seconds of the video, the airplane entered a climb and completed a 4-point aileron roll. The airplane continued to climb briefly after
Probable cause
The pilot’s loss of airplane control while performing an aerobatic maneuver, which resulted in the airplane entering an inverted flat spin at an altitude too low for recovery.
