- 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
- Initial climb
- 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

- 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 pilot reported that, while the airplane was on final approach to the airport, he realized that it was too high, so he performed a slip to lose altitude; however, due to the excessive speed and descent rate, the airplane subsequently landed hard just before midfield and bounced twice. The pilot then added full power to initiate a go-around. However, the airplane would not climb at a sufficient rate to clear the trees at the end of the runway. The airplane collided with a tree and subsequently impacted the ground adjacent to the departure end of the runway. Postaccident examination of the airplane revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
The calculated density altitude was 7,697 ft mean sea level and the airplane was about 46 lbs under its maximum gross weight at the time of the accident. It is possible that these issues adversely affected the airplane's climb rate during the go-around.
Probable cause
The pilot's delayed decision to go around after realizing that the airplane’s airspeed and altitude were too high, which resulted in an inadequate flare and bounced landing and a subsequent go-around in high-density altitude conditions.

- 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.
