NTSB narrative
THE PLT WAS TAKING A FRIEND AND TWO OF HER ACQUAINTANCES ON A SIGHTSEEING RIDE WHEN THE ACFT CRASHED INTO A PLOWED FARM FIELD. THE ACFT'S WEIGHT WAS ESTIMATED TO BE 60 LBS UNDER MAX ALLOWABLE GROSS WEIGHT AT THE TIME OF THE CRASH. A WITNESS NEAR THE CRASH STATED THAT THE AIRCRAFT WAS FLYING LOW, CLEARING A POWERLINE JUST BEFORE THE CRASH. SHE SAID THE ACFT WAS NOSE LOW AND TRAVELING AT A HIGH RATE OF SPEED. INVESTIGATION REVEALED NO PREIMPACT PART FAILURE OR MALFUNCTION. A CHECK OF THE PLT'S LOGBOOK REVEALED THAT THE PLT HAD 133.4 HOURS WITH 5.6 HOURS LOGGED IN THE PREVIOUS 12 MONTHS.

- 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 1986-04-18.
