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 PERFORMED A PRETAKEOFF INSPECTION OF THE GLIDER, BOARDED AND BELTED IN A PASSENGER, AND HOOKED THE GLIDER TO THE TOW PLANE. HE THEN ENTERED THE GLIDER AND SIGNALED TO THE TOW PLANE THAT HE WAS READY FOR TAKEOFF. HOWEVER, HE NOTICED AN IMBALANCE IN TRAVEL OF THE LEFT RUDDER, OPENED THE COCKPIT AND SIGNALED THAT HE WAS ABORTING THE FLIGHT. HE WAITED MOMENTARILY TO ASSURE HIMSELF THAT THE TOW PILOT HAD GOTTEN THE SIGNAL; WHEN THERE WAS INACTION ON THE PART OF THE TOW PILOT, THE GLIDER PILOT EXITED THE COCKPIT TO VISUALLY INSPECT THE RUDDER AREA. WHILE THE GLIDER PILOT WAS OUT OF THE COCKPIT AND THE PASSENGER IN THE REAR SEAT, THE TOW PILOT INITIATED A TAKEOFF. SUBSEQUENTLY, THE TOW PILOT RELEASED THE GLIDER AND IT CRASHED IN A TRAILER PARK.

NTSB Probable Cause

IMPROPER DECISION OF THE GLIDER PILOT TO EXIT THE GLIDER WITHOUT POSITIVE ASSURANCE THAT THE TOW PILOT HAD RECEIVED HIS SIGNAL OR THAT THE GLIDER WAS RELEASED FROM THE TOW PLANE. A RELATED FACTOR TO THE ACCIDENT WAS: THE LACK OF CREW COORDINATION BETWEEN THE PILOTS.
