Are you sure you want the AFM?
Can't speak specifically to the J31 but most AFM are Limitations and Performance data with the minimum of procedures documented to meet certification requirements. The perf data is mostly single engine stuff.
Pilots at larger operators frequently never actually see the AFM. The Ops or Dispatch groups use it to more.
From an operating the ac point of view, pilots are apt to be much more interested in the QRH,AOM,and FCTM.
