Probable cause
FAILURE OF THE PILOT TO MAINTAIN CONTROL OF THE AIRCRAFT DURING TAKEOFF, DUE TO SPATIAL DISORIENTATION, WHICH RESULTED IN A COLLISION WITH THE TERRAIN. CONTRIBUTING FACTORS WERE: DARK NIGHT, PILOT'S VISUAL PERCEPTION, INADEQUATE INITIAL TRAINING OF THE PILOT BY THE OPERATOR, THE PILOT'S LACK OF FAMILIARITY WITH THE GEOGRAPHICAL AREA, AND THE COMPANY'S INSUFFICIENT STANDARDS/REQUIREMENTS.

- 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 1989-06-02.
