Thats kinda erie. A 210 out of KPWK about two months ago broke up in flight over Marion Wisconsin.

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.
On October 26, 2004, about 1125, a Cessna P210N, N5485W, piloted by a private pilot, was destroyed during an in-flight break-up and subsequent impact with terrain near Wautoma, Wisconsin. The personal flight was operating under 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident. An Instrument Flight Rules flight plan was on file and was activated. The pilot and passenger were fatally injured. The flight originated from the Palwaukee Municipal Airport, near Wheeling, Illinois, at time unknown and was destined for the Pine River Regional Airport, near Pine River, Minnesota.
Federal Aviation Administration data showed that the flight was in contact with an air traffic controller. Preliminary information showed that the flight advised the controller that it was losing its gyros and needed to go to a lower altitude. The flight reported that it was ok but had a problem a minute ago. The flight then reported it entered clouds. The flight's last transmission was that it was going into a spin. Radar contact was lost at that time.
Two witnesses reported to the Waushara County Sheriff's office that they observed the flight while they were planting trees on their property. In the sheriff's report of their statement, the witnesses indicated that they heard thunder or jets flying. The report showed that they heard a "high winding noise from [the] plane engine". The noise was directly above their position. They heard a loud bang. They reported seeing a plane at about 1,500 to 2,000 feet above ground level. The airplane was observed spinning straight down without its wings. The witnesses indicated that they observed something hanging from its tail section.
At 1154, the Alexander Field South Wood County Airport, near Wisconsin Rapids, Wisconsin, recorded weather was: Wind 060 degrees at 13 knots with gusting to 20 knots; visibility 10 statute miles; present weather light rain; sky condition overcast 1,300 feet; temperature 8 degrees C; dew point 6 degrees C; altimeter30.19 inches of mercury.
At 1153, the Fond Du Lac County Airport, near Fond du Lac, Wisconsin, recorded weather was: Wind 080 degrees at 10 knots; visibility 10 statute miles; present weather light rain; sky condition broken 6,000 feet, overcast 8,500 feet; temperature 10 degrees C; dew point 4 degrees C; altimeter 30.17 inches of mercury.
At 1135, the Clintonville Municipal Airport, near Clintonville, Wisconsin, recorded weather was: Wind 020 degrees at 5 knots; visibility 10 statute miles; present weather light rain; sky condition scattered 1,600 feet, broken 2,200 feet, overcast 6,000 feet; temperature 7 degrees C; dew point 6 degrees C; altimeter 30.24 inches of mercury.
At 1155, the Volk Field Airport, near Camp Douglas, Wisconsin, recorded weather was: Wind 060 degrees at 6 knots; visibility 4 statute miles; present weather light thunderstorms, rain; sky condition scattered 1,500 feet, broken 4,000 feet, cumulonimbus clouds, overcast 6,000 feet; temperature 8 degrees C; dew point 6 degrees C; altimeter 30.16 inches of mercury.
Sections of the wreckage came to rest in the southeast corner of section 10, Township of Marion. The fuselage and engine were found impacted in terrain near the bank of a pond at latitude 44 degrees 02.603' N and longitude 89 degrees 10.335'W. The found wreckage sections were recovered along a path approximately on a 180-degree magnetic heading from the furthest wreckage section to the fuselage. The distance of that path was about 2.4 miles.
An on-scene investigation was performed. The wreckage was recovered and was laid out at a Waushara County facility. All flight controls were recovered except for the left elevator. Inboard sections of both wings remained attached to the fuselage and both those wing sections were deformed upward. Examination of the right side of the vertical stabilizer revealed an indentation consistent with the shape of the wing tip and a paint transfer mark consistent with the paint color scheme on the wing tip. Examination of the right wing tip revealed an abrasion in the area of that paint. Flight control cables were traced and all brakes found were consistent with overload. Flight control cable continuity was established between the control surfaces and the fuselage. Impact damage precluded the cables' verification within the fuselage. The flaps were found in the up position. The landing gear handle was found selecting the gear up position. The auxiliary vacuum pump switch was found in the off position.
The engine was rotated by hand with a lever applying a rotational force on its propeller flange. All cylinders produced a thumb compression. The number four cylinder's exhaust valve push rod was found bent. Removed sparkplugs were tan to beige in color. Rotation of the right magneto produced spark at all terminals. The left magneto sustained impact damage. The left magneto was disassembled. Rotation of the left magneto produced spark at its center electrode. The propeller was found separated from its engine propeller flange. The propeller blades exhibited S shaped bending and chordwise abrasion. The engine tachometer indicated 2686.7 hours. The engine driven vacuum pump was separated from the engine's rear case. The pump housing was found impacted in terrain about a foot below the engine.
The attitude indicator, horizontal situation indicator, and turn coordinator were disassembled. The examination of their gyros revealed rotational scoring.
The engine driven vacuum pump, auxiliary dry air vacuum pump, and their manifold were retained for further examination.
