Abstract: A drive system for a rotorcraft includes first and second gearbox assemblies and a lubrication assembly. The lubrication assembly includes first and second lubrication systems and a valve connected between the first and second lubrication systems such that when the valve is in a first position, a test mode of operation of the lubrication assembly is enabled and when the valve is in a second position, a normal mode of operation of the lubrication assembly is enabled.
The lubrication assembly also includes a valve control unit operable to instruct the valve to selectively move between the first position and the second position.
