Dave,
While we were at the \'Dorf that change came out to move them to the galley wall. The issue was then brought up with that relocation it would prevent the pilot from expeditiously egressing the aircraft due to the space between the FEs seat and the bottles on the wall. Especially with body armor on. So, trying to make a long story short but failing, we (QA) put in a change to relocate them to the front side of FS 245, as Tiny had mentioned where the sextant was since it was going to be removed. The change was approved but I never seen it take place. I am now over in the dirt flying (as an FE) with the Rock and on a couple of Cheyenne aircraft and all the brackets are in their original location and the bottles are pulled and put on the bunk.
I don\'t believe they were going to be relocated to the galley wall out of fear of explosiveness, because the relocation put them about head/shoulder level of everyone in the flt deck, above any armor mating.
Since we are on the subject of O2 bottles. When a bottle is empty what is the proper purge procedure to reservice it? As a newbie Crew Chief in the early, early 90s I was taught service and drain 3 times, then service. Back then I would never question a Vietnam Vet expediter (if I seen him today I probably still wouldn\'t) and never seen it in writing. So anybody have any words of wisdom or tech data knowledge to pass along?
Thanks,
Mike
