- 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

- 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
- Collision with terrain/object (non-CFIT)
- 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 before takeoff he calculated the airplane weight to be 104 lbs below maximum gross weight, the takeoff distance to be about 985 ft, and estimated the wind to be from 250° at 15 knots gusting to 30 knots. The pilot departed from runway 17 and rotated the airplane for takeoff about 1,250 ft down the 2,000 ft runway. He noted that the airplane did not climb as expected, and he kept the airplane wings level in ground effect, but the airplane drifted left and collided with the runway end lights. The pilot continued the initial climb and realized that the right main landing gear tire had separated from the airplane. He continued to his destination airport and landed on the runway without further incident. Postaccident examination of the airplane revealed substantial damage to the left horizontal stabilator. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. Following the accident, the pilot assessed that wind may have shifted to a tailwind resulting in a loss of airplane performance. The closest aviation weather reporting facility was 25 nautical miles from the departure airport which reported a variable wind from 260° to 320° at 14 knots gusting to 24 knots.
Probable cause
The airplane’s collision with runway lights during takeoff due to reduced airplane climb performance. Contributing to the accident was the shifting winds during takeoff which likely developed into a tailwind.

- 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, cause areas. 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.
