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.

Full Narrative
On March 14, 1994, at 1756 central standard time, a Grumman G- 164B, N6665Q, was substantially damaged during a forced landing. The commercial pilot was not injured. Visual meteorological conditions prevailed for the aerial application flight. The pilot reported to a Federal Aviation Administration inspector that the engine lost power during the application of fertilizer. He then proceeded to dump the remainder of his load. The aircraft impacted the ground, bounced twice, and nosed over to the inverted position. An examination of the engine by a Federal Aviation Administration inspector and the owner revealed that the spark plugs were fouled. The aircraft was released to the owner.
