I'm not 100% sure how this would be a CA issue. You should talk with a Beechcraft maintenance tech before taking anything specific from the forum. Have a discussion with them about at what altitude and when are you setting the cabin controller on climb and descent. Do you have the pressure controller set to auto or manual? Where is the manual controller knob set? Where is the cabin pressure source knob set (Both Norm)?

I think the best thing you can do is to take your phone, record all the settings in flight, and then how the cabin climb and cabin altitude gauges change with the phases of flight. Go show that to the Mx guy.

If there is a Mx issue, watch out for annunciatiors in the near future...
