## Sequence of events

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

- Loss of control - in flight, landing - flare/touchdown
  - precautionary landing - selected, pilot in command
  - directional control - not maintained, pilot in command (cause)
- In flight collision with object, landing - flare/touchdown
  - object - fence

## Analysis

IN ORDER TO SLOW THE AIRCRAFT DOWN DURING FLIGHT THE PILOT LOWERED 15 DEGREES OF FLAPS. AS THE FLAPS WERE TRANSITIONING DOWN THE PILOT STATED HE HEARD A "POP SOUND" WHICH WAS NOT NORMAL. HE THEN DECIDED TO MAKE A PRECAUTIONARY LANDING ON A DIRT ROAD. DURING THE APPROACH THE FLAPS WERE LOWERED ANOTHER NOTCH. JUST BEFORE TOUCHDOWN THE PLANE VEERED LEFT INTO A FENCE, THE NOSE GEAR WENT INTO THE GROUND, AND THE AIRCRAFT FLIPPED INVERTED.
