In fact, the FAA does not recognize these terms. The FAA does not formally define “wet” and “dry” leases, but the former Civil Aeronautics Board described a “wet leasing contract” as a crewed aircraft lease and a “dry lease” as an unmanned aircraft, and the FAA adopted this terminology. The distinction becomes a problem when trying to decide who actually has operational control of the aircraft. In other words, if you rent your plane to the public for air travel, does your leasing activity start to look like a charter operation? Far 135.25 contains general aircraft requirements for 135 operators. If the leased aircraft is proposed as the only aircraft used by the operator, pay close attention to the “exclusive use” requirements of FAR 135.25. The rules require that each Part 135 operator have the “exclusive use” of at least one aircraft for the type of operations authorized by the operator. Pure leasing may be legal, but some terms carry the test such as “wet erzage” and “lezaire.” In general aviation, many people refer to an aircraft that has been leased with fuel in the leasing lot as “wet leasing.” When the pilot has to pay for the fuel in addition to the time rental rate, this is commonly referred to as “dry rent.” Many flying clubs and flight schools call their hourly rental fees for a plane with fuel included as “wet fare.” A “lease” is a contract by which the owner of another person or company authorizes the use of that property for a certain period of time for a certain amount of money. The owner – called the “lessor” retains ownership of the property, and the person who pays the owner for the use of the property is called “reading.” If you are considering any of these agreements, pay attention to the language in the rental documents to make sure they are using the correct terminology. Incorrect use of either term would probably not cause major legal problems, but if you are dealing with an asset as expensive as an airplane, it is worth correct. You can also explore to rent your aircraft to a holder of a Part 135 certificate for charter operation.
