There are many situations in which an operator may want to make its aircraft available to a third party. Usually this can be accomplished via a non-exclusive dry lease.
Leasing transfers possession of the aircraft without transferring the title. A dry lease furnishes an aircraft, but the lessor provides no crew. A lease that includes crew is called a “wet lease,” and requires an FAA commercial certificate – unless specifically authorized under FAR 91.501 or FAR 91.321.)
Additional costs not included are fuel costs, pilot costs, and management fees. Management fees: $1,000 / month.
