On June 12, 2020, at 1950 eastern daylight time, an experimental amateur-built Vans RV8, N553KM, was substantially damaged when it was involved in an accident at Henry County Airport (HMP), Hampton, Georgia. The airline transport pilot was seriously injured. The flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.
During the airplane’s initial climb after takeoff, witnesses reported hearing the engine misfire and seeing black smoke trailing the airplane. The pilot performed a 180° turn and approached the departure runway in the opposite direction and overflew the airport environment. The airplane subsequently entered a 180° turn for landing on the departure runway and impacted terrain in a flat attitude at the approach end of the runway. The landing gear and cockpit canopy separated, and the wings and the fuselage were substantially damaged. Video of the accident captured the airplane in steep pitch and roll attitudes at low altitude.
A detailed postaccident examination of the engine revealed that the fuel nozzle on the No. 2 cylinder was blocked and the spark plugs (top and bottom) revealed signatures consistent with "rich" mixtures in the Nos. 1 and 4 cylinders and "lean" mixtures in the Nos. 2 and 3 cylinders. The blocked fuel nozzle likely resulted in the partial loss of engine power.
Probable Cause: The pilot’s excessive maneuvering at low altitude following a partial loss of engine power which resulted in an aerodynamic stall and collision with terrain.
