EASA aircraft being imported from Non-EU Countries (currently referred to as SHINE (Second Hand Imported aircraft from a Non-EU state)) require an airworthiness review to be carried out and presented to the CAA at the time of survey. EASA Part M, M.A.904 and AMC include a check flight report as part of the documentation needed to support the airworthiness review.
EASA has agreed that UK oversight of light sport aircraft with an EASA Permit to Fly will include Check Flights as part of the EASA process. Consequently, for initial issue of the Permit to Fly for the first-of-type on the UK Register, or subsequent aircraft with significant differences, a Check Flight will be required.
