## Probable cause

LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS AND THE UNSUITABLE TERRAIN ENCOUNTERED DURING THE FORCED LANDING.

## Sequence of events

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

- Loss of engine power, cruise - normal
  - reason for occurrence undetermined, pilot in command (cause)
- On ground/water collision with object, descent - emergency
  - object - tree(s)
  - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (cause)

## Analysis

WHILE MANEUVERING THE ENG QUIT PRODUCING POWER. THE RT WING SEPARATED AFTER COLLIDING WITH A TREE DURING THE LANDING ROLL; THEREFORE, NO DETERMINATION COULD BE MADE IF THE SUPPLY WAS CONTAMINATED.  THE REMAINING FUEL SUPPLY WAS CHECKED FOR CONTAMINANTS; NONE WERE FOUND. THE ENG WAS STARTED & FOUND TO OPERATE NORMALLY.  NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE LOSS OF ENG POWER.
