Incident Overview
A pilot flew an aircraft to Boone County Airport to have the carburetor adjusted. Following the adjustment, the pilot took off to the south from a grass runway adjacent to the concrete runway. While climbing through approximately 300 to 400 feet above ground level (AGL), the engine began running roughly. The pilot elected to turn and return to the airport for landing.
Sequence of Events
On the final approach, the aircraft crossed over a building area at a low altitude. The pilot observed one of two persons on the ground ahead and realized a collision course was imminent. To avoid striking the person, the pilot pushed the control stick forward in an attempt to bounce the aircraft off the concrete and over the individual. However, the landing gear failed upon impact, causing the aircraft to skid 236 feet across the ramp and into a grass area. Both persons on the ground were struck by the aircraft.
Fuel Mixture
The pilot stated that a mixture of automotive and aviation fuel was being used in the aircraft at the time of the incident.
Damage
The aircraft sustained damage to the landing gear and subsequent skid marks were observed on the ramp. The extent of injury to the persons on the ground is not specified in the available information.
