The NTSB's narrative final · quoted from the NTSB record
The purpose of the flight was to perform a cyclic-rigging check, and a rotor-rpm check during autorotation. The pilot and a friend performed a preflight inspection, and neither noted any mechanical deficiencies. The pilot started the helicopter, and performed the run-up checks, to include the magneto check and the rotor-engagement check with the helicopter "light on the skids." The pilot then completed the before takeoff checks, and initiated a takeoff to a hover. As the pilot applied collective pitch and power for takeoff, he felt a few bumps. He was aware of the phenomena of ground resonance, and continued applying collective pitch and power, but the helicopter would not take off. Within seconds, he had no control of the helicopter, as it disintegrated around him. The friend's version of the events leading up to the accident was consistent with the pilot/owner's. According to the witness, "It happened so fast! It started to shake, a blade hit the tailboom, and it shook to pieces." He added that the helicopter never left the ground, and that it rocked side-to-side two or three times before it came apart.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number IAD05LA075.
