Cessna T210F accident near Monticello, New York, July 15, 2022

On July 15, 2022 at about 4:45 pm local time, a 1966 Cessna T210F, registered N6195R, was destroyed in an accident during enroute (cruise) near Monticello, New York. It was a personal flight under general aviation rules (Part 91). No one was hurt; 1 person was on board or involved. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

Maintenance personnel’s improper torque of the engine through-bolts during maintenance, which resulted in a bearing shift, oil starvation, and a total loss of engine power.

The NTSB's narrative final · quoted from the NTSB record

The pilot was descending toward the destination airport when the engine began losing power and “making noises.” The pilot 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 landed on a road with the landing gear retracted, and the airplane slid to a stop. The airplane caught on fire, and the pilot egressed before the cockpit was consumed. Postaccident examination of the engine revealed that the Nos. 5 and 6 connecting rods were fractured. The No. 5 connecting rod was missing and the No. 6 connecting rod exhibited thermal discoloration consistent with a loss of lubrication. The crankshaft and camshaft were fractured at the No. 5 cylinder. Review of the engine logbook revealed that about 100 flight hours (5 months) before the accident flight, engine through-bolt nuts were removed and resealed for oil leaks. Given this information, it is likely that maintenance personnel did not properly torque the crankcase through-bolts, which allowed the No. 5 main bearing to shift, resulting in loss of lubrication to that area and subsequent engine failure.
