On August 06, 2023, about 0927 Pacific daylight time, a Grumman G164A, N5450, sustained substantial damage when it was involved in an accident near Davis, California. The pilot sustained fatal injuries. The airplane was operated as Title 14 Code of Federal Regulations Part 137 aerial application flight.
The pilot was flying an aerial application flight over a tomato field from west to east when the airplane impacted a field and was consumed by a postimpact fire. There were no witnesses to the accident.
Postaccident examination of the airplane revealed substantial impact and thermal damage to the airframe and its corresponding systems. Impact signatures on the propeller revealed leading edge gouges, chordwise scratches on the face side of one propeller blade, and aft bending on both propeller blades in the opposite direction of rotation, which is consistent with some rotation at the time of impact.
The propeller exhibited some indication of power at the time of impact; however, the impact and thermal damage prevented a determination to what extent the engine was operating at the time of the accident.
- Probable Cause: An inflight loss of control during a low altitude operation for undetermined reasons.
