Narrative:
The crew accepted the aircraft out of maintenance for a reposition flight. The aircraft was in maintenance for a leaking oxygen mask harness. The appropriate sign-offs were completed and the aircraft was green. On arrival [after reposition] the co-pilot oxygen mask fell out of the holder. That is when the first officer realized that the whole harness assembly was upside down. The orientation of the harness would not have allowed for a quick don of the oxygen mask and may have prevented the proper placement of the mask. I wrote the issue up in the aircraft log and contacted maintenance. The first officer did check the inflation of the harness with particular attention to any leaking. No leaks were detected. Both he and I failed to catch that the whole harness was improperly installed prior to our reposition flight. Closer attention to detail would have allowed us to detect the improper equipment. We would not have repositioned if this issue was known.
