In preparation for a Florida trip later this week, N833DF is in for oil change and recurring AD compliance inspections.
Only unexpected squawk is that the rotating beacon / belly strobe breaker has tripped. It is possible that this can interfere with my plans, but probably not.
The interior work complicates the diagnostics. I reviewed pictures and found the breaker tripped when I picked it up, but my pre-flight got lazy on the beacon and breakers. I was seeing what I expected to see.
I will handle the leaky air vent on my own after the airplane comes back.
