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.

WRECKAGE AND IMPACT INFORMATION The airplane wreckage came to rest on a paved road, upright, facing a magnetic heading of 130°. The field that the pilot was spraying was to the east of the accident site and was bordered on three sides by power lines. Damaged power lines were located on the western edge of the field. Portions of the left wing were scattered around the powerlines and to the north of the wreckage. The airplane engine was driven near vertical into the edge of a paved road about 7 yards west of the damaged powerlines. A post-impact fire consumed a majority of the left wing, fuselage, and empennage. Figure 1 Accident Site (Photo from Monona County Sheriff's Office) Examination of the airplane did not reveal any preimpact anomalies which would have precluded normal operation.
