On July 20, 2022, about 1845 central daylight time, a Beech N35 airplane, N1228Z, was substantially damaged when it was involved in an accident near Wardsville, Missouri. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight.
The pilot reported the flight was uneventful until he was approaching the destination airport. During the approach, he observed the oil pressure drop to zero and, shortly afterward, the engine started running rough. The pilot subsequently heard a “bang' from the engine and observed smoke from under the engine cowling. The engine lost power completely and he executed a forced landing to a field. The airframe sustained substantial damage to the forward fuselage.
Postaccident examination revealed that the engine failed because of oil starvation. At the time of the examination, the aftermarket oil filter adapter was loose and not safety wired in accordance with the manufacturer's instructions and the Federal Aviation Administration (FAA) airworthiness directive.
Probable Cause: Engine failure due to oil starvation resulting from an oil leak at the improperly installed aftermarket oil filter adapter.
