NTSB narrative

THE OWNER OF THE NEW HOME BUILT ACFT HAD GIVEN THE PLT PERMISSION TO TAXI THE PLANE, BUT NOT TO TAKEOFF. THE PLT STATED THAT HE INADVERTENTLY BECAME AIRBORNE WHILE MAKING A HIGH SPEED TAXI CHECK, THEN THE ENG LOST POWER. A WITNESS STATED THAT THE ACFT BECAME AIRBORNE WHEN IT WAS APRX HALF WAY DOWN THE RWY, THEN IT CLIMBED ABOUT 30 FT, TRAVELED APRX 250 FT OFF THE END OF THE RWY & BEGAN LOSING ALTITUDE. THE PLT INITIATED A LEFT TURN & CRASHED IN AN OPEN FIELD. THE ACFT HAD NO PREVIOUS FLT TIME & THE PLT HAD NO PREVIOUS FLT TIME IN THE MAKE & MODEL. DURING THE INVESTIGATION, THE PLT & OWNER COULD NOT BE CONTACTED TO VERIFY THE CIRCUMSTANCES OF THE REPORTED ENG FAILURES.

  • 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.
  • API snapshot SHA-256: 2322017a2a79343fb4f926f3c44a46b99c0b03e0c4e266137a20bf6cbbb4b240; retrieved 2026-09-21T17:48:27.854Z.
