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.

WPR11CA286
The pilot stated that he loaded the hopper of the airplane with chemicals for an agricultural flight and proceeded to take off. During the initial climb, at approximately 50 feet above ground level (agl), the pilot noticed a tailwind from the southwest and at 60 feet agl noticed that his climb rate had diminished. He performed a forced landing in the wash across a main road, and on touchdown the main landing gear separated and the airplane proceeded inside a gully where the wings sustained substantial damage. At the time of the accident, the density altitude was approximately 3,600 feet. The pilot reported no mechanical issues or malfunctions that would have precluded normal operation and he felt that he was unable to attain an adequate flying speed due to the high humidity.

Full Narrative
The pilot stated that he loaded the hopper of the airplane with chemicals for an agricultural flight and proceeded to depart on runway 30. During the climb out, at approximately 50 feet above ground level (agl), the pilot noticed a tailwind from the southwest and at 60 feet agl noticed that his climb rate had diminished. The pilot attempted to initiate a forced landing in the wash across a main road. On touchdown the main landing gear broke off and the airplane proceeded inside a gully where the wings sustained substantial damage. The pilot reported no mechanical issues or malfunctions that would have precluded normal flight. At the time of the accident, the density altitude was approximately 3,600 ft.
