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.

The 15,600 hour commercial rated pilot was initiating the first aerial application flight of the day and decided to make the takeoff with a full fuel load and full hopper of chemicals on an upslope runway. The airplane was not able to establish an initial climb and began to settle back to the ground. The pilot attempted to dump the chemical load, but was unsuccessful and the airplane impacted the ground and cart wheeled, coming to rest in the upright position. The pilot was not injured and was able to exit the aircraft unassisted. The airplane sustained substantial damage to the wings, landing gear, engine case, propellers, and empennage. Weather reported at the time of the accident was winds 340 degrees at 23 knots gusting to 28 knots.
NTSB Probable Cause
The pilot's improper decision to takeoff uphill with full fuel and fuel chemical load. A factor was the pilot's failure to calculate performance data.
