I applaud your desire to learn more about your aircraft. And don’t feel embarrassed, my experience is that few pilots truly understand the AStar hydraulics (including the yaw load compensator). In addition, with the advent of the B3 there are also single and dual hydraulic systems that further muddy the waters. Also, your use of an accident report is a great asset to expand your understanding, however, this forum is the last place. Time spent with a knowledgeable instructor is the best method to learn this information. There is no substitute for a factory course or an enviroment like FlightSafety, etc.
Having said that, you might find these reports useful after obtaining adequate instruction:
Hydraulic cutoff switch: (Canadian report) A05F0025
Accu Test Switch: (Canadian report) A06P0123
Dual hydraulic accident: (US report) CEN15MA290 (includes information of pedal loads)
