NTSB narrative
ABOUT 5 TO 10 MIN PRIOR TO THE ACDNT, SVRL WITNESSES IN THE VICINITY OF THE WILLOW ARPT SAW THE ACFT HEADED SOUTHBOUND. THEY RPRTD THE ENG WAS RUNNING ROUGH, BUT THEY SAW NO SMOKE OR FIRE. APRX 3 MI FURTHER SOUTH, OTHER WITNESSES SAW THE ACFT MAKE A 180 DEG TURN BACK TWD THE ARPT. THEY RPRTD THE ENG WAS RUNNING ROUGH & THEY BELIEVED BLACK SMOKE WAS TRAIL- ING FROM THE LOWER ENG AREA. AS THE ACFT CONTD TWD THE ARPT, OTHERS HEARD &/OR SAW THE ACFT. SOME RPRTD THE ENG WAS RUNNING VERY ROUGH. OTHERS CLOSER TO THE ARPT SAW NO SMOKE & SVRL THOUGHT THE ENG WAS NOT RUNNING. ONE WITNESS NEAR THE ARPT STATED THE AIRSPEED WAS SLOW JUST BEFORE THE ACFT HIT TREES AT THE EDGE OF A WOODED AREA. THE ACFT CRASHED & BURNED APRX 1600 FT FROM THE APCH END OF RWY 31. AN EXAM OF THE WRECKAGE & A TEARDOWN OF THE ENG WERE MADE, BUT NO PREIMPACT MECHANICAL MALFUNCTION OR FAILURE WAS VERIFIED. HOWEVER, THE ACFT WAS EXTENSIVELY DAMAGED BY IMPACTED & FIRE.

- 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 1986-07-28.
