OOP ( Out of Phase ) Code N, if memory serves me right on the Phantom FGR2.
AD470 Tx / Rx ( HF Long Range Radio ) presurisation - every 28 days !!
Only trouble was it was behind Panel 61 L ( L for Left ) just in front of the stabiliser.
Lots of screws to remove the access panel, presurise with dry Nitrogen, lots of screws back in, oops, on the last screw, one of the anchor nuts fell out and was the wrong side of the panel !!
Lots of screw out, put said anchor nut back in place, lots of screws back in, oops - another anchor nut fell out - repeat the above !!!
End result was it got "signed off" as being done next time it was due- oops
