NTSB narrative
DURING THE TAKEOFF ROLL, IT APPEARED TO THE PLT THAT THE ENG WAS NOT DEVELOPING FULL POWER. THE ULTRALIGHT WAS NOT EQUIPPED WITH A TACHOMETER & THE SUSPECTED LOSS OF POWER WAS BASED ON THE PLT'S ESTIMATED LIFT-OFF POINT. THE PLT FURTHER STATED THAT HE WAS WEARING A HELMET & THE ENG NOISE WAS MUFFLED MAKING IT DIFFICULT TO DETERMINE ENG POWER. THE TAKEOFF RUN WAS LONGER THAN NORMAL. HE CONTINUED TO CLIMB OUT & WITH WHAT APPEARED TO BE A PARTIAL LOSS OF POWER ATTEMPTED TO SET UP A GLIDE. THE ULTRALIGHT STALLED WHILE THE PLT WAS AVOIDING TREES. TWO WITNESSES STATED THAT THE ENG QUIT.

- 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.
