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.

The pilot said that he was practicing touch-and-go landings. After one of the takeoffs, he pulled the throttle back to practice an aborted takeoff from an altitude of 50 feet above ground level (agl). He lowered the flaps and performed a three-point landing. He added power for takeoff again, but had only climbed 3 feet agl before impacting a 4-foot fence at the end of the 3,675-foot-long gravel runway. The airplane came to rest upright with its left main landing gear bent back under the fuselage. The left wing sustained structural damage.
