- 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
- In flight collision with object
- 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

- 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
TAKEOFF WAS FROM A DIRT DRIVEWAY WHICH HAD A USABLE LENGTH 0F 330 FT BEFORE IT CURVED NORTH. BEFORE TAKEOFF, THE PLT HADBENT SEVERAL SMALL TREES BACK AWAY FROM THE DRIVEWAY & TIED THEM DOWN SO THEY WOULD NOT INTERFERE WITH THE TAKEOFF. THERE ARE NUMEROUS TREES SURROUNDING THE AREA, WITH AN OPENING AT THE DEPARTURE END OF AOUT 40 FT WIDE. THE WINGSPAN OF THE ACFT WAS 38 FT 6 INCHES. AS THE PLT TRIED TO FLY THRUUGH THE OPENING, THE LEFT WING CONTACTED A TALL TREE & THE LEADING EDGE SLAT SEPARATED. THE ACFT ROLLED & CRASHED INVERTED ONTO A GUARD RAIL OF AN ADJACENT HIGHWAY. THE ACFT WAS EQUIPPED WITH AN AUTOMOBILE RESTRAINT SYSTEM. THE SHOULDER HARNESS ATTACHING BRACKET WAS LOCATED AT THE TOP OF THE BENCHSEAT. THE SHOULDER HARNESS STRAP CAME LOOSE FROM THAT ATTACHING POINT DURING THE CRASH SEQUENCE. THE ACFT HAD BEEN REPORTEDLY REBUILT BY THE PLT WHO IS NOT AN A&P. THERE WERE RIVETS MISSING IN THE VERTICAL STABILIZER, & WHERE HOLES DIDN'T MATCH UP, NEW ONES WERE DRILLED & SCREWED TOGETHER.

- 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 1983-07-20.
