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 conducting tree trimming operations on a power line right of way that consisted of a 10-blade aerial saw that was slung below the helicopter. During the cutting, a saw blade snagged a 1/2-inch cable that wrapped itself around the lower saw blades. A section of the cable broke off and struck the tail rotor assembly, damaging the stabilizers and tail rotor drive shaft. The helicopter lost all tail rotor authority and began an uncontrolled yaw, impacting the trees as it descended to the terrain where it came to rest on its left side. The impact resulted in substantial damage to the airframe and rotor blades. The operator did not report that there were any preimpact mechanical failures or malfunctions of the helicopter that would have precluded normal operation.
NTSB Probable Cause
An encounter with a foreign object, which resulted in a loss of control and collision with terrain.
