Accident Details
On August 18, 2015, at approximately 1025 central daylight time, a Cessna 182P single-engine airplane, registration N6KW, departed the runway surface during a precautionary landing at Bolivar Municipal Airport (M17) in Bolivar, Missouri. The private-rated pilot sustained minor injuries, and the airplane was substantially damaged. The airplane was owned by a private individual and operated by the pilot as a personal flight under 14 Code of Federal Regulations Part 91. Day, visual meteorological conditions prevailed, and no flight plan was filed. The flight departed Joplin Regional Airport (JLN), Joplin, Missouri, and was destined for Spirit of St Louis Airport (SUS), St. Louis, Missouri.
Electrical Failure
During cruise flight, the airplane experienced a total electrical failure. The pilot elected to divert to M17 for a no-flap landing.
Landing and Impact
The pilot reported that the airspeed was too fast on landing, and she landed long on the airport's 4,000-foot runway. With the excess speed, she was unable to keep the airplane on the runway. The airplane went through the grass, struck a ditch, and nosed over, coming to rest inverted.
Wreckage Examination
Examination of the wreckage showed the lower forward fuselage crushed upward, the nose gear broken aft, the right wing bent downward at the root, and the right wing strut bent inward at mid span. The top 12 inches of the vertical stabilizer and rudder were bent to the left about 70 degrees. Flight control continuity was confirmed. The airplane's voltage regulator and alternator were retained for further examination.
Post-Accident Component Testing
The alternator was examined at Aerotech of Louisville, Incorporated, Louisville, Kentucky, on January 19, 2016. It passed all functional testing, and a disassembly inspection of its components showed no anomalies. The voltage regulator was examined at Lamar Technologies, Marysville, Washington, on January 27, 2016. The voltage regulator, part number VR600 and manufactured in June 1996, failed the functional test.
Pilot Information
The pilot reported 185 total flight hours, with 90 hours in the airplane make and model. No other anomalies were found with the airplane.
