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
During a pleasure flight, just after take-off, the engine experienced a partial loss of power when the plt positioned the carb heat control to full cold. The plt stated that in order to obtain full power, during the runup he would position the carb heat to one eighth hot. Inspection and a flow test of the carb revealed that the carb would sustain engine operation. There were no mechanical failures or malfunctions reported. The temperature recorded at Mammoth Lakes airport 13 minutes after the accident was 82 degrees. The density altitude was 10,300 feet. The dew point was not recorded therefore the probability of carburetor icing could not be determined.
