NTSB narrative
BOTH AIRPLANES HAD ENTERED THE TRAFFIC PATTERN FOR LANDING. THE PILOT OF THE CESSNA 150, N6059J, STATED THAT HE HAD REPORTED HIS LOCATION AND INTENTION TO ENTER THE UPWIND LEG OF RWY 17 WHEN HE WAS 2 MI NW OF THE AIRPORT. WHEN THE CESSNA 150 WAS ABOUT MID-FIELD, ANOTHER AIRPLANE, A PIPER ARCHER, ANNOUNCED HE WAS ALSO ON THE UPWIND LEG OF RWY 17. THE CESSNA PILOT REPORTED TO THE PIPER PILOT THAT HE HAD HIM IN SIGHT. THE PILOT OF THE HOMEBUILT CHALLENGER RECOUNTS REPORTING ON THE RADIO 3 MI EAST OF THE AIRPORT, AND THEN AGAIN ENTERING 45 DEG TO THE DOWNWIND LEG OF RWY 17.
Probable cause
THE FAILURE OF THE PILOT OF THE CESSNA 150, N6059J, AND THE PILOT OF THE CHALLENGER TO SEE AND AVOID EACH OTHER.

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. 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.
