On September 4, 2023, at 1031 eastern daylight time, a Beech A36, N1WN, was substantially damaged when it was involved in an accident near Frankfort, Kentucky. The pilot and three passengers were not injured. The flight was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot stated that he had performed a preflight inspection with no anomalies noted before departing Gary/Chicago International Airport (GYY), Gary, Indiana with his passengers for a flight to Greenwood County Airport (GRD), Greenwood, South Carolina. He began the flight with full fuel tanks and the fuel selector set to the right fuel tank. He flew for about an hour before switching to the left fuel tank. About 30-40 minutes later, while in cruise flight at 7,000 ft mean sea level, the engine stopped producing power and the propeller continued to windmill. The pilot disengaged the autopilot, advanced the throttle, and established best glide speed. He declared the emergency to air traffic control who advised him that the nearest airport was Capital City Airport (FFT), Frankfort, Kentucky, about 8 nm ahead. The pilot took no further remedial actions to restore engine power. When he realized that the airplane would not reach the runway at FFT, he landed with the landing gear retracted on airport property, where the airplane slid across a taxiway, struck a taxiway light, and came to rest in the grass. Postaccident examination of the airplane revealed that the fuselage sustained lateral scraping and gouging along the belly skin, which was wrinkled aft of the firewall. The left wing was damaged consistent with ground contact. The engine mount structure was bent upward about 3º. Postaccident examination of the fuel strainer screen and fuel strainer bowl revealed they were free from debris. Both wing fuel tanks were intact and contained fuel, with the fuel tank caps seated in place. The fuel was tested with water finding paste and was free from contamination. All fuel screens were free of obstructions. Although the inboard fuel vent tubes were obstructed by insect nests, air was passed through the remainder of the fuel vent system with no restriction to airflow noted, and testing of the fuel boost pump revealed that fuel flow was not restricted even with the restricted vent. All spark plugs showed normal wear when compared to a Champion Aerospace Aviation Check-A-Plug chart. Borescope examination of the cylinders revealed no anomalies. Thumb compression was achieved on all cylinders when the propeller was rotated by hand. The impact-damaged propeller was replaced with a serviceable one and the ignition switch was bypassed since the ignition key was not present for the examination. The engine was started using the airplane’s battery, which had retained its charge since the accident. The engine idled at 700 rpm. The right magneto was disconnected, and the engine was started on the left magneto only and ran normally. The right magneto was reconnected, and the left magneto was disconnected, and the engine was started on the right magneto only and ran normally. The crankshaft was slightly bent and produced vibration, so the engine was not operated above idle. Examination of the airframe and engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane. The airplane was equipped with an engine data monitor; however, no data was recovered from the engine data monitor since the data recording was a user configurable option on the device and was not configured to record any data. Review of maintenance logbooks revealed that the engine had accumulated less than 30 hours since factory overhaul.
