Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

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.
NTSB Probable Cause
The pilot’s improper preflight fuel planning, which resulted in fuel exhaustion and the subsequent total loss of engine power.
Full 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.
