NTSB narrative
THE PLT STATED THAT SHORTLY AFTER A NIGHT DEPARTURE, THE ACFT ENTERED A FOG BANK. THE PLT SAID HE WAS TURNING TO REVERSE DIRECTION AND DESCENDING IN ORDER TO AVOID IMC. PRIOR TO COMPLETING THE TURN, THE PLT ENCOUNTERED IMC AND LOST ALL OUTSIDE VISUAL REFERNCE. ACCORDING TO THE PLT, HE LEVELED THE ACFT'S WINGS AND PULLED BACK ON THE YOKE JUST PRIOR TO GROUND CONTACT. THE PVT PLT WAS NOT INSTRUMENT RATED AT THE TIME OF THE ACCIDENT.

Source notes (4)
- 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 1985-12-16.
