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 the pilot, after an aerial tow aloft he soared in thermals above nearby ridges as he flew toward the San Luis Reservoir. As the thermals began to dissipate he turned back toward Hollister and took what he described as the long route to [the airport]. The lack of available lift precluded making the airport and he landed in an open field. As the right wing dropped, the tip snagged in a large gopher hole and the aircraft ground looped, damaging the wing and empennage.

NTSB Probable Cause

the pilot's improper in-flight decision to take a longer than necessary route back to the airport during a period of marginal lift.
