The NTSB's narrative final · quoted from the NTSB record
While en route, the left and right hydraulic system failure lights illuminated. The pilot diverted to an alternate airport. The pilot was unable to extend the landing gear using the normal system. The pilot tried the emergency system but the gear still would not extend. The pilot was forced to land wheels up after diverting to an alternate airport. The airplane's keel sustained substantial damaged during the landing. An examination of the airplane showed a hydraulic line had failed downstream of the left and right hydraulic pumps and the emergency landing gear extension air bottle, making gear extension impossible.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 CEN09CA343.
