Probable cause

The pilot in command's inability to effectively eliminate carburetor ice to avoid an emergency landing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(partial) - nonmechanicalCruise
Weather condition - carburetor icing conditions
Carburetor heat - not possiblePilot in commandCause
Forced landingDescent - emergency
On ground/water collision with objectLanding - roll
Object - tree(s)

Analysis

While in cruise flight the engine began to lose power and run rough. The pilot had experienced carburetor icing during a low power ground run previously. He believed this to be the reason for the current partial loss of power. He was unable to maintain flight and initiated an emergency landing on a roadway. He was unable to stop the aircraft prior to impact with a tree. The engine was not equipped with carburetor heat.
