- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Approach
- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Aerodynamic stall/spin

NTSB narrative
Radar data indicated that, when the accident airplane was about 1 nautical mile southwest of the airport, another airplane entered a left downwind leg for the landing runway. The first airplane was on the base leg of the traffic pattern when the accident airplane entered the left downwind. The accident airplane's speed slowly decreased as it continued the downwind leg, and the first airplane landed when the accident airplane was turning toward the base leg at about 69 knots groundspeed. Shortly thereafter, the airplane descended and impacted a residential area about 1/2 mile from the runway threshold. A witness saw the accident airplane enter the traffic pattern shortly behind the first airplane. As the first airplane landed, the accident airplane was on base to final flying “low and very slow,” like it was “waiting for” the first airplane. The left wing dropped, and the airplane descended to the ground. Postaccident examination of the airframe and engine revealed no anomalies that would have precluded normal operation. Based on the available information, the accident is consistent with the pilot’s exceedance of the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall, loss of control, and impact with terrain. It is possible that the pilot may have been distracted by the airplane landing in front of him, which contributed to his loss of situation awareness regarding the airplane’s speed.
Probable cause
The pilot's exceedance of the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall and loss of control.

- 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.
