Two men who died in a single-engine plane crash after taking off from Buchanan Field Airport in Concord last month have been identified by the Contra Costa County coroner's office.
Renato Simone, 58, from Danville, and Leon Dwulet Jr., 67, from Orinda, were killed when the Beechcraft A36 Bonanza they were in went down shortly after takeoff on Oct. 25, according to the coroner's office.
Investigators have not yet said which of the men was flying the plane at the time.
The Beechcraft crashed in a hilly area between Concord and Pittsburg near Nortonville Road after striking power lines at about 12:30 p.m., a little more than three minutes after taking off, according to a preliminary accident report released by the National Transportation Safety Board last week.
The report doesn't give a cause for the crash but does say the plane was recently installed with new navigation equipment, and the purpose of the flight was to familiarize the pilot with the new devices.
It was the second flight with the new equipment, according to the NTSB. The first was when a flight instructor flew the plane to Concord from Jackson in Amador County, where the equipment was installed.
