## Probable cause

AN UNDETERMINED LOSS OF ENGINE POWER.

## Sequence of events

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

- Loss of engine power, approach - vfr pattern - final approach
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll

## Analysis

AT THE END OF A CROSS COUNTRY PLEASURE FLIGHT, THE PILOT REPORTED THAT WHILE ON FINAL APPROACH FOR LANDING, THE ENGINE QUIT. A LANDING ON THE RUNWAY WAS NOT POSSIBLE; THEREFORE, THE  PILOT INITIATED AN EMERGENCY LANDING TO AN OPEN FIELD, SHORT OF THE RUNWAY.  DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH THE TERRAIN. DURING THE POST CRASH INVESTIGATION, THE ENGINE WAS PREPARED FOR A TEST RUN. THE ENGINE STARTED IMMEDIATELY AND WAS RUN FOR SEVERAL MINUTES WITH NO NOTED MECHANICAL FAILURE OR MALFUNCTION.
