In some examples, an aircraft gearbox comprises a housing, a barrier, a rotatable drive system component, a set of gears, and a lubrication system. The barrier separates a first compartment and a second compartment within the housing. Each of the rotatable drive system component and the set of gears operable to rotate based on torque received from an engine. The rotatable drive system component is located in the first compartment. The set of gears is located in the second compartment. The lubrication system comprises a first lubrication subsystem and a second lubrication subsystem, which are, at least in part, independent from one another. The first lubrication subsystem is operable to lubricate the rotatable drive system component in the first compartment. The second lubrication subsystem is operable to lubricate the set of gears in the second compartment. The barrier inhibits lubricant from passing between the first compartment and the second compartment.
