## Probable cause

THE LOSS OF ENGINE POWER. A FACTOR WAS THE UNSUITABLE TERRAIN.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, cruise - normal
  - engine assembly,connecting rod - failure,total (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - none suitable (contributing factor)

## Analysis

DURING CRUISE FLIGHT THE AIRPLANE LOST TOTAL ENGINE POWER AND THE PILOT EXECUTED A FORCED LANDING TO A SOFT FIELD. DURING THE LANDING ROLL THE AIRPLANE NOSED OVER TO THE INVERTED POSITION. EXAMINATION OF THE AIRPLANE REVEALED A FAILED MASTER ROD IN THE ENGINE.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
