Remember to also Lockwire the filter again when you do him up. Sorry for stating the obvious but make sure you lockwire it so that the wire is "doing it up" if you will.
Another question.
If you have been shown by a LAME and "signed off" on sched 8 can you sign off the MR for that item. I.e. Can PlankBlender sign off the MR as 50hrly oil change completed?
