Accident occurred Tuesday, October 25, 2016 in Nortonville, CA
Aircraft: BEECH A36, registration: N364RM
Injuries: 2 Fatal.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On October 25, 2016, about 1230 Pacific daylight time, a Textron Aviation Beech A36 Bonanza, N364RM, was destroyed when it impacted powerlines and terrain in a steep descent shortly after departure from Buchanan Field Airport (CCR), Concord, California. The private pilot/owner and the certificated flight instructor (CFI) received fatal injuries. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed. 

According to persons familiar with the pilot, airplane, and/or CFI, the airplane had recently undergone an installation of a new avionics suite, and the purpose of this flight was for the CFI to assist the pilot in becoming familiar with the new avionics. The airplane was based at CCR, but the avionics installation was accomplished at Westover Field / Amador County Airport (JAQ) Jackson, California, and the CFI was reported to have flown the airplane back from JAQ to CCR without the pilot. That was reported to be the first flight of the airplane since the maintenance, and the accident flight was the second flight. The new avionics suite was reported to have consisted of Garmin 750 and 600 devices; they replaced a previous Garmin suite of similar devices.

CCR fuel records indicated that the airplane was fueled with 37.0 gallons on the day of the accident flight. Air traffic control (ATC) audio communications and ground tracking radar information indicate that the airplane departed from CCR runway 19, and made a left turnout shortly thereafter. The airplane continued to climb in a relatively straight track to the east, with a climb rate of about 800 feet per minute. About 3 ½ minutes after takeoff, the airplane reached its maximum radar-indicated altitude of about 3,600 feet, and then commenced a left turn of about 20 degrees and a steep descent. The radar data indicated that the airplane descended at a rate of about 5,000 fpm. No communications from the airplane after takeoff were captured. 

The airplane struck two high tension powerlines and then the ground. Ground impact site elevation was approximately 590 feet, and the struck powerlines were situated about 200 feet above the impact site, and about 300 feet southwest of it. The powerlines were oriented approximately perpendicular to the flight path, and consisted of 6 lines total, with 3 lines on either side of the tower. The vertical separation of the lines was about 15 feet, and the horizontal separation was about 30 feet. The airplane first struck the middle line of the Pittsburg-San Mateo line, and then the lower line of the Pittsburg-East Shore. About 25 fracture separated sections of the airplane, consisting primarily of empennage aerodynamic surfaces, were scattered below the powerlines and in the field between the powerlines and the impact site. A post impact fire consumed much of the airplane at the impact site.

Federal Aviation Administration (FAA) information indicated that the airplane was manufactured in 1995. The pilot had owned the airplane for about 10 years. The airplane was equipped with a Continental Motors IO-520 that was field converted to a TIO 550 series, including a Tornado Alley brand turbocharger. A large quantity of maintenance records was on board the airplane at the time of the accident; they were thrown clear of the fire by the impact, and survived. The most recent annual inspection was completed in May 2016, at which time the airplane had about 2,626 total hours in service. The engine maintenance records indicated that the engine had about 2,382 total hours in service, and 681 hours since major overhaul, at the time of the annual inspection. 

The pilot held a private pilot certificate with airplane single-engine land and instrument rating. The CFI also held ground instructor and airline transport certificates. Their experience levels were not available at the time of this report. 

The 1220 CCR automated weather observation included winds from 180 degrees at 12 knots, visibility 10 miles, scattered clouds at 4,200 feet, overcast layer at 11,000 feet, temperature 68 degrees C, dew point 52 degrees C, and an altimeter setting of 30.07 inches of mercury.

CONCORD, CA – 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.




PITTSBURG — Investigators continued Wednesday to probe a small plane crash that killed its pilot in the hills near Pittsburg.

The Beech A36 Bonanza went down in the foothills near the Black Diamond Mines Regional Preserve just after 12:30 p.m. on Tuesday, authorities said. The pilot, the plane’s only occupant, died amid the wreckage and has not been identified, and authorities said Tuesday they do not anticipate being able to do so for several days.

A National Transportation Safety Board spokesman said the agency remained in the area and that it will have an preliminary report in a week.

Crews found the wreckage shortly after 1 p.m. on private property near the park on the western end of the Black Diamond Mines, along Nortonville and Kirker Pass roads, authorities said.

A web site devoted to tracking flights, FlightRadar24.com, appears to show the plane reaching 3,000 feet then falling sharply, a path that matches what witnesses described.

The plane’s tail number indicates the plane was owned by Accretion, LLC, a Portland, Oregon-based company that, according to its LinkedIn page, is devoted to outsourcing and offshoring.

Federal Aviation Administration spokesman Ian Gregor confirmed the plane left from Concord’s Buchanan Field at 12:15 p.m. on Tuesday after arriving from Westover Field in Amador County on Oct. 20.

Crews with Pacific Gas and Electric de-energized two power lines near the crash site Tuesday to assess damage and make repairs, spokeswoman Lynsey Paulo said.

That work, carried out in conjunction with investigators assessing the crash, had no impact on nearby customers and was expected to be completed late Wednesday, Paulo said.
