A lot of private pilots who own N reg aircraft and fly them in EASA land, with American IFR rating will be deemed to be the operator. So a huge amount hinges on the residency of the operator/pilot. I can find no definition of resident in the context of an aircraft operator or pilot, and previous posts have said that there seems to be no definition.....so how do I know as a UK pilot operator, who spends over 6 months with my aircraft, out of EASA land, whether I have to qualify under JAR?
