With the HAM6 +X door off we did an initial inspection of HAM6, looking for anything that could have caused the pressure spikes seen in 78346, 78432. 

There was discoloration on the fast shutter, see lower half of the -X part of the "fast shutter cap" and viton piece: part (4) and  (10) of D1003318. Photos attached.  This was the only thing we could see out of the ordinary. 

From the Feb 2024 HAM6 closeout photos in 75791, this photo shows the fast shutter and no discoloration can be seen. 

We'll plan to inspect the fast shutter when closed today.
