The pin is checked by everybody who enters/works in cockpit,it is only 'fitted' by the pilot unless on deeper maintenance than first line
Yes, I appreciate that, and I would not go anywhere near a seat without checking the position of the pin(s) very carefully. Having said that I would have thought that part of the A/F servicing for an armourer would be to
ensure that the seat pin was correctly located. If the aircraft was going into the hangar then pins should be in the safe for servicing position, which includes the firing sear.
It is so basic.
If it doesn't say that, what does it say?

NOTE
My post #489 should have said A/F not B/F
