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
WPR12CA229
During an aerial application pass, the pilot mistakenly descended the airplane too early and struck a pipe on a center pivot irrigation system. As a result, the left main landing gear sustained damage, and the pilot flew the airplane back to the airport to land. The pilot stated that the airplane ground looped upon touchdown due to the damaged landing gear. The airplane's left wing was damaged during the ground loop. The pilot reported that there were no mechanical malfunctions or failures with the airplane prior to striking the object.
NTSB Probable Cause
The pilot’s failure to maintain adequate clearance from an object during an aerial application, which resulted in damage to the landing gear and led to the airplane ground looping during the subsequent landing.
Full Narrative
The pilot stated that the purpose of the flight was to perform an aerial application on a wheat field. During a pass, he mistakenly descended the airplane too early and struck a pipe on a center pivot irrigation system. As a result, the left main landing gear sustained damage, and the pilot flew the airplane back to the airport to land. Upon touchdown, the airplane ground looped due to the damage incurred by the landing gear. The airplane's left wing was damaged during the landing. The pilot reported that there were no mechanical malfunctions or failures with the airplane prior to striking the object.
