## Probable cause

THE LOST OF ENGINE POWER FOR UNDETERMINED REASONS.

## Sequence of events

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

- Loss of engine power, go-around (vfr)
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing
  - terrain condition - high vegetation (contributing factor)
- Nose over, landing - roll

## Analysis

THE TWO PILOTS WERE PRACTICING LANDINGS WHEN A GO AROUND WAS INITIATED. THE ENGINE LOST POWER SHORTLY AFTERWARDS. A FORCED LANDING WAS MADE IN A FIELD BEYOND THE RUNWAY END, WHERE THE AIRPLANE NOSED OVER.  THE EXAMINATION OF THE AIRPLANE DID NOT DISCLOSE EVIDENCE OF MECHANICAL MALFUNCTION.
