NTSB narrative
THE SURVIVING RIGHT SEAT PASSENGER, A PRIVATE PILOT WITH ABOUT 440 HRS TOTAL FLIGHT TIME, STATED THAT THE STUDENT PILOT/ACFT OWNER WAS PERFORMING A GO-AROUND WHEN THE ACFT STALLED, TURNED LEFT, DESCENDED UNCONTROLLED, STRUCK A TREE BY THE RUNWAY, AND IMPACTED THE GROUND. THE TOXICOLOGY REPORT ON THE STUDENT PILOT REVEALED A BLOOD ALCOHOL LEVEL OF 0.191%.
Probable cause
THE STUDENT PILOT'S ALCOHOLIC IMPAIRMENT OF EFFICIENCY AND JUDGEMENT RESULTING IN HIS FAILURE TO MAINTAIN AIRSPEED DURING A GO-AROUND.

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 1992-03-16.
- API snapshot SHA-256: 43905e9127a1ae8edb8b71bf43fdc61c2c6b942c745ca06d88fdbc8c92cfee0a; retrieved 2026-09-21T01:18:49.821Z.
