Dry lease
A dry lease hands over the aircraft only: the lessee supplies its own crew, maintenance oversight, insurance and operational control, and is responsible for the flight from a regulatory point of view. It is the normal structure for financing an aircraft through a bank or lessor, for companies sharing an aircraft between related entities, and for owners who want to fly under Part 91 with their own pilots. Dry leases are legitimate and common, but they are also the vehicle most often abused in illegal charter schemes, where a broker 'leases' the aircraft to a passenger for a single trip while secretly providing the pilots. Regulators look hard at who really controls the flight.
