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 May 27, 1994, approximately 1100 mountain daylight time (MDT), a Piper PA-12, N3960M, impacted terrain approximately 10 miles East of Nashua, Montana while conducting aerial application activities. The private pilot, who was the sole occupant of the airplane, received serious injuries, and the aircraft sustained substantial damage. The aerial application flight, which departed a private airstrip near Nashua, Montana approximately 15 minutes earlier, was in visual meteorological conditions at the time of the accident. No flight plan had been filed and there was no report of ELT activation. The pilot stated that the aircraft was heavily loaded. He said he was in a turn and didn't have enough airspeed. The aircraft stalled with insufficient altitude to recover.
