On May 16, 2021, about 1545 Pacific daylight time, a Cessna 210 airplane, N7350E, was substantially damaged when it was involved in an accident near Lake Arrowhead, California. The pilot and passenger were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot reported that the engine lost partial, then total, power while flying over mountainous terrain. The pilot initiated a forced landing to a clearing, during which the airplane collided with vegetation and came to rest upright on a steep slope, resulting in substantial damage.
Examination of the airplane revealed that the fuel flow manifold valve failed to open when fuel pressure was applied on a test stand. The fuel flow manifold valve was disassembled; tooling marks were observed on the plunger, and the seal near the plunger was deformed and not seated flat on the manifold body. The plunger assembly and diaphragm were substituted in the fuel flow manifold valve, reattached to the test stand, and performed within manufacturer specifications. The malfunction of the fuel flow manifold likely resulted in the total loss of engine power.
Probable Cause: A total loss of engine power due to a malfunction of the fuel flow manifold valve.
