## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing
  - terrain condition - ground

## Analysis

THE PLT STATED THAT THE ENGINE RAN GOOD DURING THE RUN UP & ON HIS TAKEOFF ROLL THE ACFT ACCELERATED NORMALLY UNTIL HE REACHED 45 KNOTS, HE LOOKED DOWN AND NOTICED THAT THE CARBURETOR HEAT WAS ON & HE WASN'T GETTING ANY MORE POWER. REALIZING HE WAS GOING TO HIT THE FENCE, HE PULLED BACK ON THE STICK & GAVE THE ACFT FULL RIGHT AILERON, CLEARED THE FENCE, & CRASHED INTO A PASTURE. AN ATTEMPT WAS MADE TO RUN THE ENGINE IN FRONT OF THE FAA AT THE ACFT SALVAGE FACILITY. JUST AS THE ENGINE WAS BEING READIED TO START THE PILOT TOLD EVERYONE TO STOP & GET AWAY FROM HIS ACFT, WHICH WAS DONE. THEREFORE THE LOSS OF POWER WAS UNABLE TO BE DETERMINED DUE TO THE PILOTS REQUEST THAT NO ONE TOUCH HIS ACFT.
