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 may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
On August 3, 2016, about 1155 central daylight time, a Sonex Limited Waiex airplane, N12YX, impacted terrain following a partial loss of engine power near the Fond du Lac County Airport (KFLD), Fond du Lac, Wisconsin. The private rated pilot and flight instructor were both seriously injured. The airplane was substantially damaged. The airplane was registered to and operated by Sonex Ltd under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which operated without a flight plan.
According to preliminary information obtained by investigators, the pilots were performing touch-and-go landings at KFLD. Shortly after takeoff, the pilots reported a loss of engine power. During the forced landing, the airplane collided with a transmission line and impacted terrain. An inspection of the airplane revealed substantial damage to the fuselage and both wings.
The airplane was retained for further examination.
A pilot and passenger practicing landings and takeoffs at the Fond du Lac County Airport Wednesday experienced engine failure when their plane lost altitude, hit a guide wire and crashed, the Fond du Lac County Sheriff's Office said Thursday.
A complete investigation into the crash of the single-engine plane is being conducted by the National Transportation and Safety Board. The official findings could take months to complete, said airport manager John Wehner.
The passenger, David Plathe, 60, of Dedham, Massachusetts, was flown from the scene by Flight for Life to ThedaCare Regional Medical Center in Neenah. He was released Thursday, according to a hospital spokesperson.
St. Agnes Hospital could not release information on the condition of the 73-year-old pilot, Thomas Helm from Neenah, the spokesperson said.
The plane, owned by Sonex Aircraft LLC in Oshkosh, took off from the airport shortly before 12:30 p.m. Helm, who was training Plathe how to fly the aircraft, attempted to return to the airport but did not have enough altitude and struck a power line before crashing into the edge of a corn field southwest of the airport property along Esterbrook Road.
This was the second plane crash in Fond du Lac within a week's time. On July 30, a time when the Fond du Lac County Airport was busy due to EAA AirVenture in Oshkosh, a single-engine airplane crashed in the northwest corner of the airport. David Spencer and Rafael Chavez from Santa Fe, New Mexico, were critically injured.
Wehner said the two crashes in one week are not related to airport operations. The crashes represent a streak of bad luck, he said. The July 30 crash was the first at the airport since the 1990s.
Wisconsin State Patrol, Fond du Lac Fire/Rescue and the Fond du Lac Fire Department and First Responders aided at the scene.
FOND DU LAC - Fond du Lac was the scene Wednesday of a second plane crash within a week's span.
A single-engine Sonex airplane that took off from Fond du Lac County Airport shortly before 12:30 p.m. clipped a power line and dropped almost instantly about 40 feet to the ground, injuring both the pilot and passenger.
Alisha Adams, who lives at N6311 Esterbrook Road, was about to go swimming with her kids for the day when she heard what she thought was a tractor crash.
“All of the sudden I heard a (sound) and a loud explosion,” Adams said. Looking out her side window, she saw the downed aircraft and people nearby, who had rushed to the scene to give aid.
The pilot, a man in his 70s from the Neenah area, was transported by ambulance to St. Agnes Hospital in Fond du Lac. The passenger, a man in his 50s, was transported by Flight for Life to ThedaCare Regional Medical Center in Neenah, according to Fond du Lac County Sheriff’s Capt. Rick Olig.
Apparently the plane, owned by SONEX Aircraft LLC out of Oshkosh, was practicing takeoffs and landings and had taken off heading west when it banked and the wing caught a guide wire of an electrical power line, spinning the plane backward.
It came down on its belly at the edge of a cornfield skirting Esterbrook Road, the first major street west of the airport, near Grove Street. Both men were conscious and able to answer questions, Olig said.
Mark Schaible, general manager at Sonex, said the pilot was on contract with the company providing transition training to a customer who had purchased a Sonex aircraft kit to build his own plane.
Customers often train with one of Sonex’s certified flight instructors to gain familiarity with the aircraft before flying it on their own, Schaible said.
“Right now our concern is with the occupants (of the plane) and have learned both are in stable condition,” Schaible said Wednesday afternoon.
The same type of company-owned Sonex plane crashed in Oshkosh on June 2, 2015, killing Sonex CEO Jeremy Monnett and assembly mechanic Mike Clark, a new employee with the company. Schaible said he couldn’t speak as to whether the accidents were similar.
Last week, on July 30, as Fond du Lac County Airport was busy with flyers arriving for EAA AirVenture in Oshkosh, a single-engine airplane crashed in the northwest corner of the airport. David Spencer and Rafael Chavez from Santa Fe, New Mexico, were critically injured.
Esterbrook Road was closed Wednesday between Forest Avenue Road and Rogersville Road while emergency and power crews from Alliant Energy work at the scene.

TOWN OF FOND DU LAC (WLUK) -- Two people were hospitalized following a plane crash in the Town of Fond du Lac Wednesday afternoon.
The Fond du Lac County Sheriff's Office says the crash happened around 12:15 p.m. just south of the intersection of Esterbrook Road and Grove Street in the Town of Fond du Lac. That's just west of the Fond du Lac County Airport.
The pilot, a Neenah man believed to be in his 70s, was taken by ambulance to St. Agnes Hospital in Fond du Lac. The passenger, a man believed to be in his 50s, was airlifted to ThedaCare Regional Medical Center-Neenah. He was listed in good condition Wednesday afternoon.
According to the sheriff's office, the pilot was practicing taking off and landing at the airport. The plane had just taken off, headed west, when the wing tip clipped a power line, causing the plane to slingshot into the ground.
The two-seat experimental aircraft is owned by Sonex Aircraft of Oshkosh.
Authorities are recommending drivers avoid the area as utility crews repair the power lines.
