Saturday, June 15, 1996 17:45 CDT
NTSB Narrative Summary Released at Completion of Accident
The aerial application flight experienced a gradual power loss during its initial climbout from takeoff. The pilot landed in a field with a soft surface. The airplane nosed over upon touchdown. Examination of the airplane's engine revealed no mechanical aniomalies that would prevent the prodiuction of normal power. The pilot said he had fueled the airplane and checked for water in the fuel before takeoff. He said he had not encountered carburetor ice during previous takeoffs earlier in the day. The pilot said the engine had hesitated on takeoff during the past 2 to 3 weeks. He said it did this on a random basis. The pilot said the airplane's engine had been idling about 5 minutes before takeoff. He said he did not apply carburetor heat when he noticed the power loss. According to an FAA carburetor icing probability chart, the temperature/dew point at the accident site posed a serious threat for carburetor icing at low power settings.
NTSB Probable Cause Narrative
the pilot not using carburetor heat when the engine began to lose power. Factors in this accident were carburetor ice formation and the soft landing surface the pilot had to use for landing.
