- 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

- First occurrenceThe 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
- Loss of control in flight
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Stall
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The certificated flight instructor and student pilot/owner took off with the winds from 330 degrees magnetic at 18 knots. After practicing in the local training area, they flew to another airport 31 miles to the east. After entering the traffic pattern, they noticed the windsock favoring runway 36 and estimated the wind to be 5 knots. During the first attempt at landing, the student pilot was too high and fast, and a go-around was executed. Throughout the go-around and traffic pattern, the student and CFI did not notice any changes in the wind. On descent to the runway, the CFI stated that the '(air)speed needle jumped from 75 to 60 and the airplane started sinking in a pre-stall configuration. Before the student had time to react, I pushed the nose of the airplane down in an attempt to restore enough (air) speed while telling him to add power.' The airplane impacted the runway, collapsing the nose landing gear and came to rest in an upright position off the right side of the runway.
Probable cause
The student pilot's failure to maintain adequate airspeed and the certified flight instructor's inadequate supervision.

- 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.
