In some examples, an aircraft gearbox comprises a plurality of gears and a hybrid lubrication system to lubricate the plurality of gears. The plurality of gears comprises a first gear and a second gear. The plurality of gears operable to rotate based on torque received from a driveshaft. The hybrid lubrication system comprises a pressurized lubrication system and a non-pressurized lubrication system. The pressurized lubrication system comprises a nozzle to spray a lubricant onto the first gear. The non-pressurized lubrication system comprises a reservoir to catch a portion of the lubricant from the pressurized lubrication system. The second gear is operable to disperse the lubricant across others of the plurality of gears based on the second gear rotating through the portion of the lubricant.
