## Sequence of events

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

- Loss of engine power, cruise - normal
  - weather condition - carburetor icing conditions (contributing factor)
  - fuel system,carburetor - ice (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - rough/uneven (contributing factor)
  - terrain condition - dirt bank/rising embankment (contributing factor)

## Analysis

THE STUDENT PILOT WAS CRUISING AT 2000' MSL ON A SOLO FLIGHT, WHEN THE ENGINE LOST POWER. EMERGENCY PROCEDURES WERE INITIATED AND A FORCED LANDING WAS MADE IN AN OPEN FIELD. DURING THE LANDING ROLL, THE AIRCRAFT STRUCK A DIRT BANK AND WAS DAMAGED. A POST-ACCIDENT INSPECTION OF THE ENGINE REVEALED NO EVIDENCE OF A MECHANICAL PROBLEM. WHEN AN ENGINE RUN-UP WAS MADE, ALL SYSTEMS OPERATED SATISFACTORILY. WEATHER CONDITIONS WERE CONDUCIVE TO FORMATION OF CARBURETOR ICE.
