- 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/mush
- 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 PLT HAD RECENTLY PURCHASED THE ACFT. WHILE ON A X-COUNTRY TRIP, HE LANDED AT AN ARPT WITH AN ELEVATION OF 4363 FT & REFUELED. WHEN HE WAS TAKING OFF, THE DENSITY ALT WAS APRX 7089 FT & THE ACFT WAS NEAR ITS MAX GROSS WT LIMIT. SHORTLY AFTER LIFT-OFF, THE PLT RADIOED THAT HE 'WAS HAVING A LITTLE TROUBLE GAINING ALT.' HE THEN STATED THAT THE ACFT HAD PROBLEMS & HE DIDN'T KNOW WHAT THEY WERE. A STALL WARNING HORN WAS OPERATING AS HE WAS TRANSMITTING. THE ACFT SUBSEQUENTLY CRASHED IN A NOSE DOWN, LEFT WING LOW ATTITUDE WHILE AT A RELATIVELY LOW AIRSPEED. AN EXAM OF THE ENG, ACFT SYSTEMS & FLT CONTROLS REVEALED NO EVIDENCE OF A FAILURE OR MALFUNCTION. ACCORDING TO A LYCOMING REP, THE ENG WOULD HAVE BEEN PRODUCING A MIXIMUM OF 79% OF ITS RATED POWER AT A DENSITY ALT OF 7089 FT.

- 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.
