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 instructor and pilot rated student were practicing pattern work. The instructor asked the student to switch the fuel selector from the right tank to the left tank. The student moved the selector but did not look at it. He inadvertently selected the OFF position. The engine quit, and could not be restarted. The instructor landed the airplane about 50 yards short of the runway. The main landing gear wheels dug into the snow during landing roll, and the airplane nosed-over.

NTSB Probable Cause

FUEL STARVATION DUE TO THE IMPROPER POSITIONING OF THE FUEL TANK SELECTOR BY THE STUDENT PILOT.
