Remember that the DOT and FAA act separately. The fine was from the DOT, not the FAA. I don't have any insight or inside information about the FAA's actions.
Yes, all maintenance must be logged, even preventative maintenance by pilots. Column space is limited, and because I had to abbreviate the approved preventative maintenance list, I didn't have room to write about maintenance entries. I frequently speak at IA renewal seminars, and I find that even mechanics tend to be too brief in their entries, so I suspect that pilots would be worse.
