Ferry flying refers to delivery flights for the purpose of returning an aircraft to base, moving an aircraft from one base of operations to another or moving an aircraft to or from a maintenance facility for repairs, overhaul or other work.[1]
A ferry permit is a written authorization issued by a National Airworthiness Authority to move a non-airworthy civil aircraft from its present location to a maintenance facility to be inspected, repaired and returned to an airworthy state.[1]
