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.

AFTER TAKEOFF, THE PLT TURNED TO A NORTHERLY HEADING & REMAINED AT LOW ALT TO VIEW HIS AGRICULTURAL DEVELOPEMENT NEAR THE AIRSTRIP. THIS HEADING TOOK THE ACFT TOWARD HIGH TENSION POWER LINES, JUST NORTH OF THE PRIVATE STRIP. THE PLT SELECTED A FLT PATH OVER THE LOWEST SAG IN THE LINES; HOWEVER, NEITHER HE NOR THE PASSENGER SAW THE STATIC CABLES ABOVE THE MAIN TRANSMISSION LINES. SUBSEQUENTLY, THE ACFT COLLIDED WITH AN UPPER (STATIC) CABLE. THE CABLE STOPPED THE ACFT'S FORWARD MOVEMENT & IT DROPPED NEARLY STRAIGHT-DOWN TO THE GROUND.
NTSB Probable Cause
FAILURE OF THE PILOT TO MAINTAIN PROPER ALTITUDE AND HIS FAILURE TO MAINTAIN ADEQUATE VISUAL LOOKOUT TO SEE AND AVOID OBSTRUCTIONS. THE STATIC LINE (OBSTRUCTION) WAS A CONTRIBUTING FACTOR.
