## Sequence of events

- In flight collision with object, landing
  - object - fence (contributing factor)
  - clearance - not possible, pilot in command (cause)
- In flight collision with terrain/water, landing

## Analysis

WHILE MAKING A POWER OFF APPROACH TO SIMULATE A FORCED LANDING AN OVER SHOOT WAS ASSURED. THE PLT ADDED PWR AND THE ENGINE CEASED OPERATING. IN ORDER TO AVOID TREES AT THE END OF THE RUNWAY THE PILOT MADE A 90 DEGREE TURN TO LAND IN A PLOWED FIELD. THE ACFT STRUCK THE TOP OF A FENCE AND THEN STRUCK THE GROUND IN A FLAT ATTITUDE. THE ACFT THEN NOSED OVER. THE TEMPERATURE ON THE SURFACE WAS 90 DEGREES AND THE PILOT HAD BEEN USING AUTOMOBILE FUEL. NO MECHANICAL REASON FOR THE ENGINE FAILURE COULD BE FOUND.
