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 February 26, 1994, at approximately 0830 central standard time, a Grumman G-164, N730Y, was substantially damaged during landing at a private grass strip near Almyra, Arkansas. The airplane, owned and operated by the commercial pilot, was landing after a local aerial application flight. There was no flight plan filed and visual meteorological conditions prevailed. The pilot was not injured. The pilot stated he applied brakes after touchdown and the right one failed. The airplane subsequently veered left off the runway into a muddy field and nosed over. A subsequent inspection of the brake system by an A&P mechanic revealed that the right brake was locked up at the master cylinder and would not operate. No reason for the lock up was reported.
