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.

WITNESSES REPORTED THE MOTORIZED GLIDER LIFTED, CLIMBED, AND THEN DESCENDED INTO A 45 FOOT HIGH POWERLINE BEFORE IT COLLIDED WITH THE GROUND. WITNESSES STATED THE GLIDER TAKEOFF RUN WAS LONGER THAN USUAL. WITNESS STATED THE ENGINE SOUNDS WERE NORMAL. THE DENSITY ALTITUDE WAS COMPUTED TO BE OVER 4000 FEET MSL. ACCORDING TO PERFORMANCE CHARTS, THE TAKEOFF ROLL AND TOTAL DISTANCE OVER A 50 FOOT OBSTACLE WAS 1696 AND 2972 FEET RESPECTIVELY BASED ON AN ELEVATION OF 1500 FEET AND 86 DEGREE F TEMPERATURE. THE AIRFIELD ELEVATION WAS 1320 FEET, AND THE TEMPERATURE WAS 96 DEGREES F. THE GLIDER WAS DETERMINED TO BE ABOUT 15 LBS OVERGROSS. THE EXAMINATION DID NOT DISCLOSE EVIDENCE OF MECHANICAL MALFUNCTION.
NTSB Probable Cause
THE PILOT'S FAILURE TO MAINTAIN ADEQUATE AIRSPEED WHICH RESULTED IN A STALL MUSH. CONTRIBUTING WAS A HIGH DENSITY ALTITUDE CAUSING DETERIORATED AIRCRAFT PERFORMANCE, AND AN INADEQUATE PREFLIGHT PREPARATION WHICH RESULTED IN AN OVERGROSS AIRCRAFT CONDITION.
