Day Four - Replacement

Ken unscrews MKIR from the PI Rack
A working computer is nice, but it needs to be installed in the FAA certified rack. So we had to swap out the bad chassis for the good one. Here -- Ken starts removing retaining bolts.

Handle shown with MKIR
Removing the handles from the backup detector control computer was not anticipated, and much more difficult than it looks.

MKIR replacement in the rack
A little blood and sweat later -- literally -- the new system is in place. Testing was again successful and I could sleep well...

Completed and working PI Rack
But no immediate rest for us, first we had to tidy up the entire instrument control rack (which is called the "PI Rack" in SOFIA terminology) in preparation for aircraft installation in the morning!
