There is another clear reason to do so, which is finance. Buying an airplane can be a challenge for many reasons, from practicality to financial. Leasing is an attractive option that allows traders to do without the financial stress of a real purchase. This is not surprising, but it can also create a problem if a lease is entered into to circumvent FAA rules and rules. 14 CFR 110.2 defines a “water lease” as “any lease contract by which a person agrees to provide an entire aircraft and at least one crew member.” (Reference to fuel) As a general rule, the parties operating under 14 CFR Part 135 are certified carriers such as airlines operating under 14 CFR Part 121 and charter airlines. However, 14 CFR 91.501 (c) provides for certain time-sharing and exchange agreements in which the aircraft and crew are made available together. In addition, while these agreements are considered water leases, since they include both aircraft and crews, these are 14 operations under CFR Part 91, for which the parties to the transactions are not required to be air carriers. In 2007, Beijing allowed Chinese banks to launch leasing units and nine Chinese lenders were among the top 50 in 2017, led by ICBC Leasing in the top 10, with the value of their managed fleet increasing by 15% since 2016.  In some cases, Chinese owners forgot that they had to receive a secondary lease and missed the time of re-delivery when they failed planes for a few months.
 A lease agreement in which the aircraft is made available and at least one pilot. Under a water lease agreement, the aircraft is normally operated under the leaser`s AOC. In order to ensure the establishment and operation of leasing with a third-country operator, the British operator (Lessee) must first obtain prior authorisation as follows: several companies in the aviation zone not only offer aircraft for leasing, but also provide pilots, crews, maintenance certificates and even flight certificates. This is called wet lezing. Aircraft leasing is a lease of airlines and other aircraft operators. Airlines lease aircraft from other airlines or leasing companies for two main reasons: operating aircraft without financial charges and allowing temporary capacity increases. The sector has two main types of leasing: wet leasing, which is normally used for short-term leasing, and dry leasing, which is more normal for longer-term leases. The industry also uses wet and dry suits. For example, if the aircraft is leased in the water to establish new services, airline cabin crew or cabin crew may switch to a dry lease. The global wet leasing market is expected to grow from $7.35 billion in 2019 to $10.9 billion in 2029, representing a 4.1% TURNOVER.
