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.

DURING THE FIRST DEPARTURE OF THE DAY THE AIRPLANE DID NOT ACCELERATE SUFFICIENTLY TO GET AIRBORNE AND CLEAR EIGHT FOOT TALL WEEDS AT THE SOUGH END OF THE PRIVATE STRIP. THE AIRPLANE GOT AIRBORNE AT THE END OF THE STRIP BUT THE CHEMICAL SPREADER ON THE BOTTOM OF THE AIRPLANE CONTACTED THE TALL WEEDS. THIS RESULTED IN A LOSS OF AIRSPEED, AND A SUBSEQUENT COLLISION WITH AN EARTHEN IRRIGATION DIKE. THE AIRPLANE CAME TO REST ABOUT 200 FEET FROM INITIAL IMPACT AND POST IMPACT FIRE CONSUMED THE WRECKAGE. INVESTIGATION REVEALED THAT ABOUT 50 FEET OF THE STRIP WAS COVERED BY TWO FOOT TALL WEEDS AND THAT THE REST OF THE TAKEOFF SURFACE WAS A HARD SURFACE DIRT CRUST WITH A SPONGY UNDER LAYER.
NTSB Probable Cause
