According to one embodiment, a rotorcraft (101) includes a body, a rotor blade (119, 121), a drive system (111, 113) that can be operated to rotate the rotor blade (119, 121), and an emergency valve control unit (620). The drive system (111, 113) contains a first gearbox assembly (410), a second gearbox assembly (420), a first lubrication system (510) that can deliver lubricant to the first gearbox assembly (410), and a second lubrication system (520) that can deliver lubricant to the second gearbox assembly (420). The drive system (111, 113) also contains an emergency valve (541, 542, 543, 544) that can be opened to deliver lubricant from the first lubrication system (510) to the second gearbox assembly (420). The emergency valve control unit (620) can instruct the emergency valve (541, 542, 543, 544) to open.
