NTSB narrative
THE HOMEBUILT ACFT WAS BEING TESTED FOR FLT EVEN THOUGH PREVIOUS TESTS HAD PROVEN THAT THE ENGINE WOULD NOT SUPPORT FLT.THE PLT SAID THE CARBURETOR HAD BEEN IMPROVED PRIOR TO THIS TEST. THE ACFT TOOKOFF AND CLIMBED TO ABOUT 15 FT AGL AND STAYED AT THAT ALT FOR THE LENGTH OF THE RWY. WHEN THE ENGINE LOST POWER THE PLT SAID A LANDING WAS MADE OFF THE DEPARTURE END OF THE RWY. AFTER ABOUT 25 FT OF ROLL THE ACFT NOSED OVER. THE PLT SAID THAT THE LOSS OF POWER WAS DUE TO IMPROPER CARBURETOR NEEDLE VALVE SETTING. THE DENSITY ALT AT THE TIME OF THE ACCIDENT WAS ABOUT 8400 FT. THE ARPT IS 5680 FT MSL. THIS FLT WAS TO HAVE BEEN THE BASIS FOR APPLICATION FOR AN AIRWORTHINESS CERTIFICATE FOR THIS ACFT.

- 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.
