I do not know why some of you are going around in circles. The O2 bottle was installed with the SOV closed. There is no residual pressure in the line because the aircraft was on a C check, The ECAM will show ZERO when the SOV is closed. A nice amber MSG on the Door/Oxy page will show ZERO. The maintenance crew F.
.ed up and flight crew F..
.ed up. that is the end of it. To avoid this situation from happening again during any maintenance visit is to alter the company procedure and raise a duplicate inspection after such maintenance task is performed.
