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.

NTSB Number
GAA15CA196
The pilot reported that after he dropped his passenger off on a road, he departed to the east in smoky and hazy conditions. Shortly after takeoff, the helicopter impacted power transmission line wires that ran across the road. The helicopter then impacted the ground and skidded to a stop. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The helicopter sustained substantial damage to the main rotors, upper arm, and fork assembly.
NTSB Probable Cause
The pilot's failure to monitor the flight environment for adequate terrain/obstacle clearance during takeoff, which resulted in the inflight collision with power transmission line wires.
