Probable cause

Carburetor icing and the pilot's failure to use carburetor heat. A factor contributing to the accident was the transmission wires.

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.

In flight collision with terrain/waterDescent - uncontrolled

Analysis

At the conclusion of a reduced power descending spiral, without the use of carburetor heat, the pilot applied throttle and the engine failed to respond. A forced landing was executed during which the aircraft struck power lines which the pilot did not see. Surface temperature and dew point near the accident site fell into a range conducive for carburetor icing.
