Location: Prairie Du Sac, WI
Accident Number: CEN17LA090
Date & Time: 12/28/2016, 1230 CST
Registration: N6941X
Aircraft: CESSNA 172B
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The private pilot was conducting a local flight. He reported that, during the flight, the engine started to run roughly. He decided to return to the airport for a precautionary landing. About 4 miles from the airport and while lined up for landing, the pilot increased the engine throttle with no response; the airplane lost total power. He decided to land the airplane on a roadway about 1 mile from the airport. After landing on the roadway and coming to a complete stop, the pilot restarted the engine and attempted to taxi off the roadway. While he was taxiing the airplane, it struck three roadway signs and a fence, which resulted in structural damage to the left wing.
After the airplane was recovered, small amounts of water were present in the fuel from both wing sumps and the gascolator. The engine was started, ran normally, and both magnetos checked within normal limits. The loss of engine power could have resulted from water in the fuel but the definitive reason could not be determined.
Although the pilot landed the airplane successfully on the roadway after having engine power problems, his decision to taxi the airplane from the roadway and his failure to avoid the roadway signs and fence resulted in substantial damage to the airplane.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's decision to taxi the airplane from the roadway and his subsequent failure to maintain clearance from signs and a fence after a successful emergency landing following a total loss of engine power.

Factual Information
On December 28, 2016, about 1230 central standard time, a Cessna 172B single engine airplane, N6941X, registered to a private individual, sustained substantial damage after it struck roadway signs while attempting to taxi after a successful emergency landing near Prairie Du Sac, Wisconsin. The private pilot and one passenger were not injured. The flight was being conducted under the provisions of Federal Code of Regulations Part 91. Visual meteorological conditions prevailed throughout the area and a flight plan was not filed. The flight originated from the Sauk-Prairie Airport (91C), Prairie Du Sac, Wisconsin about 1130.
The pilot reported that he was flying locally at 4,500 feet after departing from 91C. The engine started to run rough and the pilot applied carburetor heat. He decided to return to the airport for a precautionary landing. About 4 miles from the airport, and lined up for landing on runway 18, the pilot increased the engine throttle but had no response. He decided to land on a roadway about 1 mile from the airport.
After landing on the roadway and coming to a stop, the pilot started the engine and attempted to taxi off the roadway. While taxiing, the airplane struck 3 road signs and an iron fence, resulting in structural damage to the left wing.
The local Sheriff closed the highway as the airplane was loaded onto a trailer and transported to 91C where it was examined by an FAA inspector. Approximately 4-5 gallons of fuel were present in each wing tank. Small amounts of water were present in the fuel from both wing sumps and the gascolator. The engine was started, ran normally, and both magnetos checked within normal limits. The fuel appeared to be automotive fuel. The pilot confirmed that he used automotive fuel. Review of the logbooks did not disclose that the airplane was approved for the use of automotive fuel.

PRAIRIE DU SAC – No one was injured Wednesday when a plane made an emergency landing on U.S. Highway 12 near the Sauk Prairie Airport.
At about 12:30 p.m., a southbound 1961 single-engine Cessna headed to the airport lost power over the Baraboo Bluffs, prompting the pilot to land unexpectedly. The plane touched down on Highway 12's southbound lanes near the intersection with Sauk County Highway Z.
The pilot, 69-year-old pilot Stephan L. Arnold of Madison, restored power after the landing and attempted to take off, but hit a road sign, causing the plane to cross the median and come to rest on the east side of U.S. 12 next to Sauk Prairie Cemetery. Arnold and his passenger were unhurt.
A pair of witnesses, Anthony Kirkus and wife Meg of Wisconsin Dells, were driving north on U.S. 12 when they saw the plane headed for their car’s windshield.
Kirkus said “the plane touched down right as we passed it going the other way, it was crazy.”
The plane did not show any outward signs of having a problem, aside from flying extremely low, Kirkus said. “Just before it landed, we saw this low-flying plane that almost hit a set of wires going across the highway,” Kirkus said. “It just missed that and then we said, ‘Well, this is definitely landing on Highway 12.’”
Deputies directed vehicles around the landing site Wednesday afternoon, temporarily slowing traffic on U.S. 12. The plane sustained moderate damage and was towed to the airport.
The Sheriff’s Office was assisted by several agencies, including Sauk City Fire, Sauk Prairie EMS, Sauk Prairie Police, the county Highway Department, the state Department of Transportation and the Federal Aviation Administration.

SAUK CITY, Wis. - The Sauk County Sheriff's Department said a plane made an emergency landing on U.S. Highway 12 just north of Sauk City on Wednesday afternoon.
Two people were in the aircraft when the plane made the landing just before 12:30 p.m. Wednesday, according to the sheriff's department. No injuries were reported.
A sheriff's chief deputy told News 3 that the plane had taken off from the Sauk-Prairie Airport in Prairie Du Sac.
The pilot, a Madison man, told deputies he lost power and landed on the road. When he regained power, he tried to take off again and hit a sign post, the official said. There was some damage to the plane, which was being towed back to the airport Wednesday afternoon.
The highway where the plane landed is just north of an airport outside of Sauk City.
A stretch of Highway 12 was closed briefly after the landing but was reopen before about 1 p.m., officials said.

Anthony Kirkus was driving, his wife, Meg, was in the passenger seat, and an airplane was headed for their car's windshield.
This was Wednesday just after noon as the couple was driving north on Highway 12 near Highway Z outside of Prairie Du Sac, adjacent to Sauk Prairie Airport and a cemetery.
"The plane touched down right as we passed it going the other way. It was crazy," said Kirkus, who lives in Wisconsin Dells.
Stephen L. Arnold, of Madison, was operating the 1960 single-engine Cessna when the plane lost power, prompting the emergency landing, the Sauk County Sheriff's Office said. Arnold and a passenger were not injured, the Sheriff's Office said.
"Just before it landed, we saw this low-flying plane that almost hit a set of wires going across the highway," Kirkus said. "It just missed that and then we said, 'Well, this is definitely landing on Highway 12.'"
"It was coming straight at us, and I thought a little optimistically that it was going to land nearby because it was not really lining up with us and then it came down," he said.
Arnold, 69, attempted to take off from the highway after the plane regained power, the Sheriff's Office said. But the aircraft struck a road sign, sending it over the median before stopping on the east side of the highway.
The moderately damaged plane was towed to the nearby airport, the Sheriff's Office said.
