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.

INADEQUATE SUPERVISION BY THE INSTRUCTOR PILOT (CFI), WHICH RESULTED IN FAILURE TO MAINTAIN AIRSPEED AND A SUBSEQUENT STALL. FACTORS RELATED TO THE ACCIDENT WERE: GUSTY/CROSSWIND CONDITIONS, THE STUDENT PILOT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS AND FAILURE TO MAINTAIN RUNWAY ALIGNMENT, AND THE CFI'S LACK OF TOTAL EXPERIENCE AS AN INSTRUCTOR PILOT.
