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.

JUST AFTER LIFT OFF THE GLIDER BALLOONED ABOVE THE TOW PLANE. THE PILOT USED ELEVATOR CONTROL TO LOWER THE ALTITUDE WHICH RESULTED IN THE GLIDER MAKING CONTACT WITH THE RUNWAY AND CAUSING DAMAGE TO THE HORIZONTAL STABILIZER. THE GLIDER CLIMBED ABOVE THE TOW PLANE AGAIN, THEN PITCHED NOSE DOWN INTO THE GROUND. ACCORDING TO THE PILOT THIS WAS HIS FIRST FLIGHT IN THIS TYPE OF GLIDER AND HE SAID HE ESTIMATED THE TRIM SETTING BECAUSE HE WAS NOT FAMILIAR WITH THE TRIM SYSTEM ON THIS TYPE OF GLIDER.

NTSB Probable Cause

THE PILOT ROTATED THE GLIDER PREMATURELY, RESULTING IN AN INADVERTENT STALL AT TOO LOW AN ALTITUDE TO ALLOW RECOVERY. FACTORS RELATED TO THE ACCIDENT WERE THE PILOT'S TOTAL LACK OF EXPERIENCE IN GLIDERS, NO EXPERIENCE IN THIS TYPE OF GLIDER, AND IMPROPER TRIM SETTING.
