NTSB narrative
AFTER THE ACFT TOOK OFF, WITNESSES HEARD A POWER CHANGE & SAW WHAT APPEARED TO BE A LEFT TURN TO RETURN TO THE GRASS STRIP. SUBSEQUENTLY, IT ENTERED A DESCENT & CRASHED IN A LEFT WING DOWN, NOSE LOW ATTITUDE. THE PASSENGER WAS TAKEN TO A HOSPITAL, BUT DIED ABOUT 9-1/2 HRS AFTER THE ACDNT. EXAMS OF THE ACFT & ENG WERE MADE. NO PREEXISTING MECHANICAL FAILURE OR MALFUNCTION WAS NOTED, EXCEPT DAMAGE TO THE WOODEN PROP WAS CONSISTENT WITH LITTLE OR NO ENG POWER. THE KLOB TWINSTAR WAS A FOLLOW-ON, TWO-PLACE ACFT THAT WAS MANUFACTURED AFTER THE SINGLE-PLACE, ULTRALIGHT, KLOB ULTRASTAR WAS PRODUCED. RPRTDLY, THE ACFT HAD BEEN EQUIPPED WITH MANY ACCESSORIES, WHICH WHEN COMBINED WITH THE WEIGHT OF THE PLT & PASSENGER, WOULD HAVE EXCEEDED ITS NORMAL GROSS WEIGHT.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
