## Probable cause

THE LOSS OF ENGINE POWER, CAUSE UNDETERMINED.  A FACTOR RELATING TO THE ACCIDENT WAS THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.

## Sequence of events

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

- Loss of engine power, descent - normal
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing
  - terrain condition - none suitable (contributing factor)

## Analysis

THE PILOT WAS DESCENDING IN IMC ON AN IFR FLT WHEN THE ENGINE LOST POWER. HE INITIATED A FORCED LANDING AND THE ACFT IMPACTED OBSTACLES WHILE HE WAS ATTMEPTING TO LAND ON A ROAD.  THERE WAS NO EVIDENCE OF MALFUNCTION OR FAILURE THAT WOULD HAVE CAUSED THE LOSS OF POWER.  THE ENGINE RAN NORMALLY AFTER THE ACCIDENT.
