Eric,
It is a good idea when you get your services done by your LAME/L2 to be there with him when he does it. Identifying and learning about the Jab, and how it operates, is one of the most rewarding things.
When Brian does services on either ours or other Jabs, I am always with him, and even though I don't fly I have become very familiar with how the servicing is done and what needs to be looked at when the certain hourlys come up.
