## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, descent - normal
  - fuel system,carburetor - ice (contributing factor)
  - carburetor heat - not used, pilot in command (cause)
  - weather condition - carburetor icing conditions (contributing factor)
- In flight collision with object, maneuvering
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, maneuvering

## Analysis

THE ACFT COLLIDED WITH TREES AND THE GROUND FOLLOWING A REPORTED LOSS OF POWER. THE ACFT HAD COMPLETED A DESCENT OF 2000-3000 FT TO OBSERVE ROCK FORMATIONS AND HAD COMMENCED A CLIMB WHEN POWER LOSS OCCURRED. THE PLT SAID THE MIXTURE WASLEFT IN LEAN POSITION AND CARBURETOR HEAT WAS NOT APPLIED DURING THE DESCENT. WHEN THE POWER WAS ADVANCED TO 25 INCHES MP THE POWER DECREASED TO 22 INCHES AFTER ABOUT 45 SECONDS WITHOUT PLT ACTION. COMPLETE POWER WAS NEVER LOST BUT THE RISING TERRAIN TRAPPED THE ACFT. THE ENGINE RAN NORMALLY IN A POST ACCIDENT CHECK. AT THE TEMPERATURE/DEW POINT COMBINATION OF 71/58 DEG F THE PROBABILITY OF SERIOUS ICING AT GLIDE POWER EXISTED.
