A lubricant manifold includes a lubricant filter head, a pump inlet channel, an inlet transfer channel, and a lubricant cooler. The lubricant filter head is configured to be coupled to a lubricant filter. The pump inlet channel is fluidly coupled to the lubricant filter head and integrally formed with the lubricant filter head. The pump inlet channel is configured to receive a lubricant and provide the lubricant to the lubricant filter head. The inlet transfer channel is fluidly coupled to the lubricant filter head and integrally formed with the lubricant filter head and the pump inlet channel. The inlet transfer channel is configured to receive the lubricant from the pump inlet channel. The lubricant cooler is fluidly coupled to the inlet transfer channel and integrally formed with the lubricant filter head, the pump inlet channel, and the inlet transfer channel.

An engine assembly includes a small air-cooled engine and a dry sump lubrication system including an external oil reservoir, wherein the dry sump lubrication system has an overall oil capacity that provides at least five hundred hours of engine oil life.

A filter assembly for an aircraft engine includes a filter housing defining an inner cavity. The filter housing has a fluid inlet and a fluid outlet for flowing a triboelectric fluid into and out of the inner cavity. A filter bowl is removably attached to the filter housing to seal the inner cavity. A filter is disposed in the inner cavity, the filter electrically coupled to the filter bowl at a first electrical connection and the filter electrically coupled to the filter housing at a second electrical connection distinct from the first electrical connection to thereby indirectly electrically couple the filter bowl to the filter housing via the filter. One or both of the first electrical connection and the second electrical connection provides a degree of freedom for the filter to displace relative to the filter housing or the filter bowl upon engagement with the filter.
