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
CEN14CA360
One witness reported seeing the helicopter transition to the west with "low power indications" and "multiple yaws." The helicopter settled to the ground and then struck a fuel trailer near the taxiway, resulting in substantial damage to the tail boom. According to the pilot, he transitioned the helicopter to a hover and taxied adjacent to the taxiway. When he attempted a forward takeoff from the hover, the "low rotor rpm warning sounded, the helicopter lost lift," and he performed a "running landing." He stated that there were no mechanical malfunctions or failures with the helicopter during the flight. An examination of the helicopter confirmed that there was nothing mechanically wrong with the helicopter.
NTSB Probable Cause
The pilot did not maintain control of the helicopter during the takeoff resulting in low rotor rpm and impact of the fuel trailer during the running landing.
