## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, landing
- Gear collapsed, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

DURING INITIAL CLIMB, AT ABOUT 100 FEET AGL, A LOSS OF POWER OCCURRED. THE PILOT MADE A SHALLOW TURN TO AVOID OBSTACLES AND LANDED IN A PLOWED FIELD. DURING LANDING ROLL THE NOSE GEAR AND RIGHT MAIN GEAR COLLAPSED, DRAGGING THE RIGHT WING. NO REASON COULD BE DETERMINED FOR THE LOSS OF POWER.
