Narrative
A Piper PA-28-181 entered the traffic pattern via a 45-degree entry to the downwind leg. The pilot transmitted intentions on the Unicom frequency and announced position on downwind, base, and final legs. While at 100 feet on short final to runway 23, the pilot observed a "yellow airplane," described as resembling a "Piper J-3" or "American Legend Cub," enter the active runway ahead of his landing. The pilot transmitted a "going around" call and initiated a go-around, overflying the airplane on the runway. As the unknown airplane began its takeoff roll, the two aircraft came together. The PA-28-181 pilot subsequently landed straight ahead on the runway. The unknown airplane continued its flight and was not located.
Aircraft Damage
Examination of the PA-28-181 revealed a point of impact on the right wing leading edge; the airplane was substantially damaged. The unknown airplane was not examined or located.
Aftermath
The unknown airplane departed the airport and its identity, operator, and condition remain unknown. No further details about the occupants or injuries were provided in the source.
