Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
According to the pilot in the tailwheel-equipped airplane, during an agricultural application flight, he accidentally loaded more fertilizer to disperse than he had initially planned, which made the airplane "heavy." He chose not to add fuel to prevent the airplane from being over its gross weight. During flight, the engine lost power, and the pilot conducted a forced landed in a dirt field that was water-logged due to recent storms. During the landing roll, the airplane nosed over. The pilot reported that "I misjudged what I believed to be a safe quantity of fuel remaining." The airplane sustained substantial damage to the rudder and vertical stabilizer. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Factual narrative
According to the pilot in the tailwheel-equipped airplane, during an aerial application flight the pilot took onboard more product to disperse than he had initially planned. The airplane was heavy, and he chose not to take on additional fuel, to prevent an over-gross weight scenario. However, during flight the engine lost power and he forced landed in a dirt field that was water-logged due to recent storms. During the landing roll, the airplane nosed over. The pilot reported that, "I misjudged what I believed to be a safe quantity of fuel remaining." The airplane sustained substantial damage to the rudder and vertical stabilizer. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
