Aircraft Accident/Incident Report
Mcrae, Georgia 31055
Thursday, August 20, 2009 16:00 EDT
NTSB Narrative Summary Released at Completion of Accident
During an aerial application flight, the pilot noticed the engine oil temperature rise and the oil pressure decrease. The oil pressure went to zero and the engine lost all power. The pilot initiated a forced landing into a soybean field. Examination of the engine found an abnormal fuel flow through the return fitting at full rich mixture setting and a leak at the mixture shaft. Additionally, the Nos. 1 and 4 piston heads exhibited thermal erosion consistent with a pre-ignition/detonation event. This type of piston damage would elevate crankcase pressure and allow oil loss through the crankcase breather system, decreasing oil pressure and increasing oil temperature.
NTSB Probable Cause Narrative
A total loss of engine power due to pre-ignition/detonation as a result of a fuel control malfunction.
