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.

NTSB Number
WPR11CA198
The pilot stated that he took off into a 15-mph headwind from a dirt strip with an 1,800-pound load of fertilizer. When the airplane was about 100 to 150 feet above ground level, he started turning into the downwind leg of the traffic pattern. The airplane began to descend as he turned and he could not maintain altitude. He had insufficient altitude to release the full load before the airplane collided with the terrain. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.
NTSB Probable Cause
The pilot’s failure to maintain adequate airspeed while maneuvering, resulting in an aerodynamic stall and collision with terrain.
Full Narrative
The pilot stated that he took off into a 15-mph head wind from a dirt strip with a 1,800 pound load of fertilizer. He climbed the airplane to around 100 to 150 feet above ground level (agl) and started the downwind turn. The airplane began to descend as he turned downwind and he could not maintain altitude. He had insufficient altitude to release all the load before the airplane collided with the terrain. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.
