## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

  - lift-off - inadvertent, pilot in command (contributing factor)
  - aborted takeoff - not performed, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

WHILE PERFORMING A HIGH SPEED TAXI RUN ON A TURF RWY THE PLT STATED THE ACFT HIT A BUMP IN THE RWY WHERE A DRAINAGE PIPE RUNS BENEATH THE SURFACE AND INADVERTENTLY BECAME AIRBORNE. THE PLT DID NOT REDUCE THROTTLE TO ABORT THE TAKEOFF AND THE ACFT STALLED AFTER THE PLT MADE A TURN TO THE EAST. THE ACFT IMPACTED THE GROUND SHORT OF GROUP OF TREES. THE ACFT WAS A RECENTLY CONTRUCTED EXPERIMENTAL AND HAD NOT BEEN CERTIFICATED FOR FLT. THE PLT STATED HE COULD NOT REMEMBER IF HE HAD CLOSED THE THROTTLE OR IF THE ENG FAILED JUST PRIOR TO GROUND IMPACT. EXAM OF THE ENG DID NOT REVEAL ANY DISCREPANCY. THE NEW WOODEN PROPELLER WAS COMPLETELY DESTROYED DURING THE IMPACT. THE PURPOSE OF THE TAXI TESTS WAS TO DETERMINE THE PERFORMANCE OF THE ACFT WITH VARIOUS PROPELLERS INSTALLED ON THE ACFT.
