Will Rogers---. .Let's look at it from a slightly different perspective.
If P4-ABC, flown by Aruban licensed pilots, has been leased to a Spanish aircarrier for that MAD-LHR flight, the rules of the country of the operator (Spain) would be used. This would apply to duty time limitations for the pilots as well. However, should Aruban regulations be more restrictive (not likely) then these would apply.
A bit like the airline Chief Pilot, must serve two masters (pilots who want MORE and management who wants LESS...payment anyway, not duty time).
If it is a private flight, and the pilots are operating with a validation (P4), then the Aruban regulations would be followed, regardless of the pilots original license (however it must remain valid for the validation to remain valid, at least for the medical requirements).
