NTSB summary

HISTORY OF FLIGHTOn August 9, 2022, about 1106 Pacific daylight time, a Sonex Aircraft Waiex airplane, N51YX, was destroyed when it was involved in an accident near Maxwell, California. The pilot sustained fatal injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the family members of the pilot, the purpose of the flight was personal and the exact route of the flight was unknown. A review of automatic dependent surveillance – broadcast (ADS-B) data showed that the experimental airplane departed runway 13 at the Colusa County Airport (O08), Colusa, California. The airplane traveled to the north of Colusa and then traveled to the west. The airplane crossed Highway I-5, then traveled to the north of Maxwell, California, where the ADS-B data terminated in a remote area populated with fields used for agricultural work. The airplane came to rest nose down, in a flat dirt field. The wreckage, which was destroyed, sustained fire damage. The airplane was equipped with a Dynon FlightDEK-D180 unit. The unit recorded about 22 minutes of data that began when the engine was started. A review of the data showed that shortly before the data ended, the airplane went from a straight and level attitude to a nose down attitude.
