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.

PLT STATED, 'I MADE ONE PASS ON LOW BOUNDRY SPREADING 100% OF SEED AND BEGAN A CLIMBING LEFT TURN TO MAKE A PASS FROM HIGH SIDE DOWN EAST BOUNDRY. I REACHED ALTITUDE OF APPROXIMATELY 300 FT AGL (ABOVE GROUND LEVEL) AND ATTEMPTED TO PASS OVER TELEPHONE DRAW RIDGE WHEN I ENCOUNTERED A STRONG DOWN DRAFT. I APPLIED FULL CLIMB POWER AND ATTEMPTED TO TURN TO LOWER GROUND BUT WAS UNABLE TO OVERCOME SINK AND CLEAR TERRAIN. I THEN FLARED THE PLANE TO A LANDING ALTITUDE JUST BEFORE TOUCHING DOWN TO MINIMIZE SPEED AND DAMAGE. I DON'T RECALL MUCH AFTER IMPACT BUT INDICATIONS ARE THAT LEFT WING AND MAIN STRUCK FIRST CAUSING 180 DEGREE COUNTER CLOCKWISE ROTATION, THEN TAIL STRUCK AND COLLAPSED LETTING PLANE LAND ON BACK ON TOP OF TAIL.' DENSITY ALT OVER THE 6700 FT MSL TERRAIN WAS 9205 FT.
