## Probable cause

AN ENGINE FAILURE FOR UNDETERMINED REASONS.  THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING WAS A FACTOR.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, maneuvering
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - none suitable (contributing factor)

## Analysis

AFTER A LOW PASS DOWN THE RUNWAY AT A PRIVATE AIR STRIP, THE PILOT APPLIED THROTTLE TO GO AROUND AND THE ENGINE DID NOT RESPOND.  HE SUBSEQUENTLY LANDED STRAIGHT AHEAD IN A ROUGH WET PASTURE.  DURING THE LANDING ROLL HE HAD TO APPLY MAXIMUM BRAKING TO AVOID A TREE LINE AND THE AIRPLANE NOSED OVER.  THE ICING PROBABILITY CHARTS PREDICTED CARBURETOR ICING AT GLIDE AND CRUISE POWER SETTINGS.  THE PILOT STATED THAT HE USED CARBURETOR HEAT. HOWEVER, THE LENGTH OF TIME AND DEGREE OF APPLICATION WAS NOT REPORTED. NO CAUSE FOR THE POWER LOSS WAS DETERMINED.
