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.

LAX08CA057
The pilot reported that during the night flight, and prior to landing, he discovered that both landing lights were burned out. During the landing, the nose of the right skid contacted the ground and the helicopter bounced back into the air and rotated to the right resulting in the tail rotor striking a hangar. The helicopter rotated about 360 degrees before impacting the ground. The helicopter sustained substantial damage to the tail rotor gearbox attachment point. The pilot reported no other abnormalities with the helicopter prior to the accident.
NTSB Probable Cause
The pilot's misjudged landing flare, inadequate bounced landing recovery, and failure to maintain directional control during a bounced landing that resulted in the tail rotor blades colliding with a hangar. Contributing to the accident was the burned out landing lights.
