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.

A PRIVATE PILOT AND HIS PASSENGER WERE ON A LOCAL LOW LEVEL FLIGHT. THE AIRPLANE WAS OBSERVED FLYING SOUTHBOUND, PARALLEL TO HIGH TENSION POWER LINES, AT AN ALTITUDE ESTIMATED TO BE 200 FEET ABOVE GROUND LEVEL. THE AIRCRAFT WAS THEN SEEN TURNING EASTBOUND TOWARDS THE POWERLINES. AS THE AIRCRAFT APPROACHED THE WIRES, THE NOSE WAS ABRUPTLY PULLED UP AND THE AIRPLANE ROLLED TO THE LEFT AND THE NOSE PITCHED DOWN. THE AIRPLANE IMPACTED THE GROUND WITH THE WINGS LEVEL IN AN ALMOST VERTICAL ATTITUDE. A POST-IMPACT FIRE ENGULFED THE AIRPLANE WITHIN SECONDS AFTER IMPACT. THE TOXICOLOGY REPORT ON THE PILOT REVEALED A LEVEL OF 0.10% ETHANOL IN THE BLOOD, 0.09% IN THE VITREOUS FLUID, 0.14% IN THE URINE, 0.07% IN THE BILE, AND 0.05 MG/L DIPHENHYDRAMINE (BENADRYL) IN HIS SYSTEM.
NTSB Probable Cause
