## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - lift-off - inadvertent, pilot in command (cause)
  - fuel system,carburetor - incorrect (contributing factor)
- Hard landing, landing - flare/touchdown
  - precautionary landing - attempted, pilot in command (contributing factor)

## Analysis

THE PILOT HAD JUST COMPLETED SOME ADJUSTMENTS TO THE CARBURETOR AND WAS MAKING A HIGH-SPEED TAXI TEST WHEN HE BECAME AIRBORNE. HE APPLIED MORE POWER TO AVOID STALLING AND IMMEDIATELY THEREAFTER, THE ENGINE STARTED RUNNING ROUGH. HE THEN DECIDED TO MAKE A PRECAUTIONARY LANDING AND LANDED HARD IN A MILO FIELD JUST BEYOND THE FENCE AT THE END OF THE RUNWAY.
