The pics below show the entire Main Landing Gear Mount Area at the aft end of the right fuselage side covered with a 6-ply BID layup, with another two separate 15-ply BID pads on top of the 6-ply base layup.  Pic #2 shows a rear seat bulkhead mock-up (note pic #2 is the earlier photo of these layups since it still has peel-ply attached).
