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.

WPR20CA092
The pilot reported that, during an agricultural application flight, he sprayed a row on the field and then climbed the helicopter to avoid wires on the south side of the field. He then turned the helicopter right and began to descend back to the field. After he cleared the wires, he entered the field's spray line and began raising the collective and noticed that the torque gauge was responding; however, he failed to arrest the descent, and the helicopter subsequently impacted terrain and came to rest on its right side. The helicopter sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to arrest the descent rate while maneuvering at low altitude, which resulted in impact with terrain.
Full Narrative
The commercial pilot reported that during an aerial application flight, he sprayed a row on the field and climbed to avoid wires on the south side of the field. He then made a right turn and began his descent back to the field. After he cleared the wires, he entered the field on the spray line and began raising the collective. He noticed that the torque gauge was responding, however, the rate of descent was not being halted and the helicopter subsequently impacted the ground and came to rest on its right side. The helicopter sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
