The NTSB's narrative final · quoted from the NTSB record
The helicopter pilot stated that he was performing a landing to a field by his workshop and was fast during the final approach. He landed hard to avoid overshooting his landing and hitting nearby power lines. The left skid dug in and the helicopter rolled over. Examination of the helicopter revealed that all three main blades were damaged, the tail rotor blades were damaged, and the tail boom was bent.

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 CEN09CA133.
