On October 8, 2021, about 1900 Pacific daylight time, a Beech B36TC airplane, N7220B, was substantially damaged when it was involved in an accident near Los Banos, California. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot reported that he flew to Paso Robles Municipal Airport (PRB), Paso Robles, California, where he refueled and was on his return flight to Gnoss Field Airport (DVO), Novato, California. He was about 10,000 ft mean sea level, when the engine lost oil pressure and the manifold pressure dropped. He immediately diverted to Los Banos Municipal Airport (LSN), Los Banos, California.
While in the descent to LSN, the engine momentarily produced partial power, but then serious vibrations were experienced and subsequently the engine lost all power. During this time, the cockpit filled with smoke and fire, and sparks were observed emanating from the engine cowling.

The pilot attempted to make the runway but then elected to conduct a forced landing on a road near the approach end of runway. The pilot opined that he struck an object during the landing roll which resulted in substantial damage to the wings.

The airplane was recovered to a secure location for future examination.
