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.

ACCORDING TO THE PILOT, HE DEPARTED FROM THE JACKSON AG STRIP AT ABOUT 0400 HOURS AFTER LOADING CHEMICALS TO BE SPRAYED ON A FIELD ABOUT 15 MILES TO THE EAST. THE NIGHT WAS DARK WITH NO MOON VISIBLE. THE PILOT SELECTED 300 FEET AGL AS A CRUISE ALTITUDE DURING THE FLIGHT TO THE FIELD. THE PILOT STATED THAT HE THINKS HE ENCOUNTERED A STRONGER THAN EXPECTED CROSS WIND WHICH BLEW HIM ABOUT ONE MILE OFF COURSE. THE AIRCRAFT STRUCK AN UNLIGHTED 'H' FRAME POWER LINE SUPPORT STRUCTURE AT A POWER STATION.
NTSB Probable Cause
FAILURE OF THE PILOT TO SELECT A CRUISE ALTITUDE WHICH WOULD ENSURE ADEQUATE CLEARANCE FROM OBSTRUCTIONS. A FACTOR IN THE ACCIDENT WAS THE DARK NIGHT WHICH INHIBITED THE PILOT'S ABILITY TO SEE THE OBSTRUCTION.
