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.

THE PILOT WAS PERFORMING A NORMAL TAKEOFF FROM A LOCAL FLIGHT TRAINING AREA AND HAD ATTAINED AN AIRSPEED OF ABOUT 60 MILES PER HOUR AND AN ALTITUDE OF ABOUT 75 FEET ABOVE GROUND LEVEL. HE STATED THAT HE SAW A SINGLE ENGINE FIXED-WING AIRPLANE ON A COLLISION COURSE WITH HIS HELICOPTER. TO AVOID A COLLISION, HE EXECUTED A HARD DIVE. THE HELICOPTER'S RIGHT SKID MADE CONTACT WITH TRANSMISSION WIRES. THE WIRE CONTACT CAUSED A LOSS OF CONTROL AND SUBSEQUENT COLLISION WITH THE TERRAIN.
NTSB Probable Cause
1) THE PILOT FAILING TO MAINTAIN VISUAL LOOKOUT, AND 2) INFLIGHT COLLISION WITH UNMARKED TRANSMISSION WIRES.
