On July 15, 2022, at 1245 eastern daylight time, a Cessna T210F, N6195R, was destroyed when it was involved in an accident near Monticello, New York. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot stated that he conducted an uneventful flight earlier during the day from Maine to Sussex County Airport (FWN), Sussex, New Jersey, to fly a potential buyer in the airplane, which he was selling. After the short flight, the pilot dropped off the potential buyer at FWN and planned to fly to Sullivan County International Airport (MSV), Monticello, New York, for fuel before returning home to Maine. Upon beginning a descent into MSV, the engine began losing power and “making noises.” The pilot verified the fuel quantity and mixture setting, and estimated that 10 gallons of fuel remained in each tank. He switched fuel tanks, but the power loss continued. He subsequently began looking for a place to land the airplane. The pilot then heard what sounded like an “explosion” from the engine. The oil service door blew open and began spewing oil and smoke from the service door opening, covering the windscreen. Smoke then began entering the cabin. The pilot reported extending the wing flaps and landing gear, but did not have time to verify extension. He identified a field as an emergency landing location. As the airplane approached the field, about 200 ft above the ground, the pilot saw high voltage power lines crossing the field and he repositioned the airplane for a landing on a road. After landing, the airplane caught on fire, and the pilot egressed before the cockpit was consumed. Postaccident examination of the airplane by a Federal Aviation Administration inspector revealed that the landing gear did not extend, and that the engine had a large section of the crankcase missing from the forward left side. The No. 6 connecting rod was laying on top of the engine and the crankshaft and camshaft were fractured. Further examination revealed that the engine was thermally damaged. The spark plug wires were burnt. The oil filter was thermally damaged. When it was cut open, metal shavings were noted in the filter element. The fuel pump was thermally damaged; however, the shear shaft was unremarkable. The oil pump was impact damaged and could not be rotated. The turbocharger was thermally damaged but rotated freely. Both magnetos were thermally damaged and would not produce spark on any leads. The oil pan was melted away and missing. The crankshaft and camshaft were fractured at the No. 5 cylinder. The propeller, oil cooler, front section of the camshaft and crankshaft were fractured off the engine. The spark plugs exhibited normal wear. The cylinder skirts on cylinder Nos. 5 and 6 were damaged by the corresponding connecting rod failures and the cylinders could not be removed. The connecting rod for cylinder No. 5 was missing. The No. 6 connecting rod was thermally damaged and discolored. The fuel flow divider was thermally damaged, and the diaphragm was melted. The propeller was thermally damaged, and one blade tip was melted away. Review of the airplane’s maintenance logbooks revealed that 105 and 106 flight hours before the accident (about 5 months), engine through-bolt nuts were removed and resealed due to oil leaks.
