NTSB narrative
The accident, an on-ground collision between two airplanes at a non-towered airport, occurred when the lead airplane in a flight of four RV-8s, which had landed and exited the runway, was struck by a Velocity not associated with the flight. Witnesses stated that the flight of four RV-8s announced their intentions to land in formation on Runway 15 over the radio and on the same frequency that the Velocity announced its intention to conduct a straight in approach to Runway 15. The Velocity arrived on final just behind the fourth RV-8, and touched down on the runway close to the approach end. The Velocity then drifted left off the runway and onto the grass. It passed to the left of the three trailing RV-8s that were still on the runway, and struck the lead RV-8, which had cleared the runway to the left on a taxiway in the vicinity of the departure end of the runway. At some point prior to the collision, engine power on the Velocity increased. Examination of the Velocity did not reveal any evidence of preimpact mechanical failures or malfunctions, and the weather in the area was conducive for visual flight rules operations.
Probable cause
The pilot of the Velocity’s failure to see and avoid the flight of four RV-8s that had landed and were in the process of clearing the runway.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
