Probable cause
The carburetor icing causing a partial loss of engine power, and the pilot's failure to maintain aircraft control leading to the inadvertent stall. A factor contributing to the accident was the conditions conducive for carburetor icing.
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.
Analysis
According to the pilot he was too high during the approach to land and initiated a go-around. The pilot reported a temporary power failure and a stall of the left wing. The airplane impacted several trees and came to rest in a nose down attitude, resulting in substantial damage. An examination of the airplane revealed no anomalies. The temperature was 73 degrees Fahrenheit (F), and the dewpoint was 57 degrees F. According to the carburetor icing chart, the conditions were conducive for "serious icing at glide power."
