The ramp fees and landing fees associated with that flight.

I interpret that to mean any
expenditure I make to maintain the aircraft at the airport in an airworthy
condition.

And you would lose your certificate at the first hearing if violated.

Admittedly, "airport expenditures" is rather abstract and might
go either way, but until it is more properly defined mighten it also cover
maintenance, hanger or tie down, and any other expense at the airport for
the aircraft? The CFR doesn't specifically say landing fee, or parking fee,
but it could have.

The CFR says "operating expenses of a flight". That is not abstract and cannot "go
either way", especially in an FAA hearing.
