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.

According to a Federal Aviation Administration (FAA) inspector, the pilot reported that he was spraying a field at a low altitude. He said that transmission wires were located near the beginning of the field. He said the airplane encountered an unexpected downdraft which shifted the flight path towards the wires. He unsuccessfully attempted to fly under the wires, but the airplane's propeller and vertical fin struck the wires. The airplane sustained substantial damage to the fuselage, both wings, the vertical fin, and empennage. According to the FAA inspector, the pilot did not report any preimpact or mechanical malfunctions with the airplane.
NTSB Probable Cause
The pilot's failure to maintain adequate clearance from transmission wires during a low-level maneuvering flight.
Full Narrative
According to the Federal Aviation Administration (FAA) inspector, the pilot reported that he was maneuvering at low-altitude to apply applicant to a field. Transmission wires were located near the beginning of his job area. The pilot stated that while overflying the wires, the airplane encountered a gust of wind which shifted the airplane's flight path towards the wires. The pilot unsuccessfully attempted to fly under the wires. The wires struck the airplane's propeller and vertical fin. Aircraft control was lost and the airplane impacted terrain. Substantial damage was sustained to the fuselage, both wings, the vertical fin, and empennage. According to the FAA inspector, the pilot did not report any mechanical malfunctions prior to the collision.
