- 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
- Post-impact
- 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
- Ground collision
- 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
- Wire
- 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 he was flying his weight-shift control trike at low altitude when it struck power lines. Subsequently, the trike descended to the ground, which resulted in substantial damage to the structural tubing. The pilot further stated that his smoke colored visor attached to his helmet prevented him from clearly seeing the power lines. The pilot reported no preimpact mechanical failures or malfunctions with the aircraft that would have precluded normal operation.
Probable cause
The pilot's failure to monitor the environment and to maintain sufficient altitude to clear power lines during low altitude flight.

Source notes (5)
- 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. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2014-06-20.
- API snapshot SHA-256: 8a7600241adec9cddc3ec3ace725ec791990d5ebd88f8268b68d2ef64f489c86; retrieved 2026-09-16T00:23:52.822Z.
- Corrected after a review of the NTSB narrative and the aircraft's make and model, which establish these values: aircraft category. COSMOS PHASE II PHASE II 582 NO SERIES is a weight-shift (trike); the manufacturer builds nothing else. The NTSB MDB codes it AIR (Airplane), which is how the aircraft was registered rather than what it is.
