Yes sir, I know that. As well as the Unwritten Rule that made us all a tad wary of complaints that might be deemed inappropriate by someone up the chain as appears to me to be in effect here....
Okay, so I'm Old School Navair Training (plus spending a few years designing/testing aircraft), but I do believe I'd have the original contractor(s) on that system as well as the aircraft flying it on an extremely hot seat with assignment to fix the problem.

This is just not acceptable.
My experience with OBOGS is limited to about 10 hours of T-45 time, post winging, during the OPEVAL. It had some quirks, but nobody was concerned about delivery of poisonous air at that time. We were more concerned with the sensitive nosewheel steering and poor spool up time on the engines. Both of those have killed people, despite being identified through every part of the acceptance process.
