What is the Airframe Mounted Accessory Drive (AMAD)?

Explanation:
The AMAD is the power interface that drives the aircraft’s engine accessories by transferring shaft power from the engine to gearboxes mounted on the airframe. On the Growler, there are two interchangeable gearboxes, each driven through a power transmission shaft from the engine. These gearboxes then drive the accessories such as hydraulic pumps, generators, and the starting system. Having two gearboxes provides redundancy and maintenance flexibility, allowing a failed unit to be swapped or serviced without pulling the engine. The other options describe components or arrangements that aren’t how the AMAD is structured.
