NTSB narrative
A Cessna 150, N1766Q, preceded the Stearman, N89X, in a left traffic pattern at the uncontrolled airport. The Cessna pilot was heard to call on downwind. The Stearman pilot reported he observed traffic on downwind and then lost sight of it. When the Stearman pilot called on downwind, the Cessna was observed on base. The Stearman pilot was then heard to call on base with traffic not in sight. A witness observed both aircraft on final. The Stearman and the the Cessna collided with the Stearman above the Cessna when the impact occurred. The right aileron separated from the Cessna and the aircraft descended to the ground. The Stearman pilot was able to continue the flight and landed at the airport. According to the Airman's Information Manual (AIM), at uncontrolled airports, traffic calls should be made on downwind, base, and final. Additionally, according to the AIM, pilots should monitor the frequency and exchange traffic information.
Probable cause
the Stearman, N89X, pilot's inadequate visual lookout. A factor was the failure of the flight instructor of the Cessna 150, N1766Q, to announce his position in the traffic pattern in accordance with recommended procedures.

- 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.
