Probable cause
The improper use of carburetor heat control, which resulted in a loss of engine power and subsequent emergency forced landing and collision with a fence. A factor to the accident was weather conditions suitable to formation of 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
The airplane was reporting surface vehicle traffic, when according to the pilot, 'engine began running rough...declared an emergency...landed in an abandoned drive in...hit a cyclone fence causing substantial damage'. The local weather at the time of the accident reported a temperature of 64 degrees f and a dew point of 60 degrees f. when these figures are plotted on a graph which depicts the probability of encountering carburetor icing, it shows a probability of 'serious icing at cruise power'.
