- 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
- Maneuvering
- 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/spin
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed

- Pilot in command(cfi) › Aerobatics, performed

NTSB narrative
THE ACFT IMPACTED THE GROUND IN AN INVERTED POSITION IN ABOUT A 30 DEGREE NOSE DOWN ATTITUDE. THE ACFT WAS OBSERVED DOING AEROBATICS WITH THE LAST MANEUVER A SPIN. THE ACFT SPUN TO AN OUT OF SIGHT POSITION BEHIND THE TREES AND A CRASH WAS HEARD. THE CFI ON THIS FLT HAD BEEN KNOWN TO PERFORM AEROBATICS IN THIS ACFT AND TO ALLOW STUDENTS TO DO THEM. THE PILOT RECEIVING INSTRUCTION ON THE DAY OF THE FLT HAD BEEN RECOMMENDED FOR AN INSTRUMENT RATING CHECK RIDE. ONE PILOT WHO HAD FLOWN WITH THIS CFI SAID LIMITED AEROBATICS HAD BEEN PERFORMED WITH HIM BUT THE CFI PERFORMED AT A POOR PROFICIENCY LEVEL DURING AEROBATICS. A NOTED AEROBATIC PILOT WHO HAD FLOWN THIS ACFT SAID IT SPUN RELATIVELY FLAT. HE STATED THAT WITHOUT TRAINING MOST PROFESSIONAL AEROBATIC PILOTS WERE UNABLE TO RECOGNIZE EITHER THE DIRECTION OR PROPER PROCEDURE FOR RECOVERY FROM AN INVERTED FLAT SPIN.

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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1983-06-23.
