- 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
- Landing
- 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
- Landing area overshoot
- 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 conducting a night landing on a runway contaminated with ice and patchy packed snow, the airplane overshot the touchdown zone. The pilot tried to fly the airplane onto the runway to avoid floating. The airplane touched down firm and the pilot applied moderate braking, but the airplane did not decelerate normally. The airplane went off the end of the runway and collided with several Runway End Identifier Lights (REILs) and a tree. The airplane sustained substantial damage to the left and right wings. The pilot reported that he did not feel modulation in the anti-lock braking system (ABS) and felt that might have contributed to the accident. An examination of fault codes from the airplane’s diagnostic storage unit indicated no ABS malfunctions or failures. An airport employee reported that he saw the airplane unusually high on the final approach and during the landing the airplane floated or stayed in ground effect before it touched down beyond the midpoint of the runway. The airplane’s long touchdown was captured by an airport surveillance video, which is included in the report docket.
Probable cause
The pilot’s failure to maintain proper control of the airplane, which led to an unstabilized approach and a long landing on a runway contaminated with ice and patchy packed snow resulting in a runway excursion.

- 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, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2020-12-14.
