- Initial climb
- 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
- Airframe, component or system failure
- 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
WITNESSES SAW THE ACFT CLIMB TO AN ALT OF ABOUT 500 TO 800 FT AGL AFTER TAKING OFF FROM RWY 32. AT ABOUT THAT TIME, THEY HEARD A LOUD NOISE FM THE ACFT, THEN THEY NOTED THAT THE ENG SOUND HAD CEASED. THE ACFT WAS OBSERVED TO MANEUVER AS IF THE PLT WAS TRYING TO RETURN TO THE RWY. THE PLT TRANSMITTED A 'MAYDAY' REPORT, STATING HE HAD 'LOST THE ENGINE.' WHILE TURNING BACK TO THE RWY, THE LEFT WING & NOSE OF THE ACFT DROPPED & THE PLANE ENTERED A LEFT DSCNDG TURN. IT IMPACTED THE GND IN A NR FLAT ATTITUDE WHILE IN A HIGH RATE OF DSCNT, THEN IT SLID INTO A TREE & BURNED. AN EXAM OF THE WRECKAGE REVEALED 1 PROP BLADE HAD SEPD FM THE HUB DRG FLT. A METALLURGICAL EXAM SHOWED THE HUB HAD FAILED FM FATIGUE. DRG THE PREVIOUS 87 HRS OF OPN, THE ACFT HAD BEEN INVOLVED IN TWO OCCURRENCES OF GEAR COLLAPSE, WHICH RESULTED IN PROP STRIKES WITH THE GND. ACCORDING TO RECORDS, THE HUB WAS INSPECTED & FOUND TO BE IN ACCORDANCE WITH THE REQUIREMENTS OF THE MANUFACTURER (MCCAULEY) & THE FAA. THE PLT'S PREVIOUS FLT TIME IN THIS MAKE/MODEL OF ACFT WAS NOT DETERMINED.
Probable cause
FAILURE OF THE PROPELLER HUB DUE TO PREVIOUS DAMAGE, WHICH RESULTED IN SUBSEQUENT FATIGUE FAILURE OF THE HUB; AND FAILURE OF THE PILOT TO MAINTAIN FLYING SPEED, WHICH RESULTED IN A STALL AND SUBSEQUENT IMPACT WITH THE GROUND. INADEQUATE MAINTENANCE/INSPECTION OF THE PROPELLER HUB (AFTER THE PROPELLER STRIKES) WAS CONSIDERED TO BE A CONTRIBUTING FACTOR.

- 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.
