NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot and passenger departed the airport’s south runway for a local flight. Several witnesses reported that the airplane reached an altitude of about 300 feet, the left wing dropped, and the airplane descended and impacted the ground in a near vertical attitude. The airplane’s ballistic parachute system was partially deployed, but the airplane was too low at deployment for the parachute to fully deploy. An examination of the airframe and engine did not reveal any preimpact abnormalities that would have precluded normal operation. A handheld global positioning system (GPS) unit was located in the wreckage and downloaded. A plot from the GPS indicated that the airplane departed from runway 18 and tracked westward in a large circle before it returned to the airport. The track then showed that the airplane descended as it approached the airport from the southwest and was aligned with the runway at an altitude that corresponded with the runway’s altitude. The airplane then climbed to an altitude of 1,027 mean sea level (msl) (about 122 feet above ground level [agl]) and started a left turn. The final GPS point showed the airplane at an altitude of 1,035 msl (about 130 feet agl) and at an airspeed of 47 mph. Based on the events, it is likely that the pilot did not maintain adequate airspeed and the airplane entered a power-on stall during takeoff.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot did not maintain adequate airspeed during takeoff, which resulted in an aerodynamic stall. Full narrative available
