You need to check the airfield information for Compiegne.
Here on the SIA website are the plates for French airfields, including
Compiegne-Marny (LFAD).
They say "Customs...: NIL" - so you
do need to stop somewhere else in France on the way.
(Originating from a non-Schengen country such as the UK, you are obliged to enter France at a Customs airfield, and during its hours of operation).
