On 1 April 2017, there were 22,368 business jets in the worldwide fleet, of which 11.2% were for sale. 5-year old aircraft residual value level is at a 56% of the list price. A new business aircraft depreciate by 50% in five years before depreciation flattens between years 10 and 15, and the owner of a 15 to 20 years old is often the last, matching luxury cars.
In the United States, business aircraft may be operated under either FAR 91 as private operations for the business purposes of the owner, or under FAR 135 as commercial operations for the business purposes of a third party. One common arrangement for operational flexibility purposes is for the aircraft's owner to operate the aircraft under FAR 91 when needed for its own purposes, and to allow a third-party charter-manager to operate it under FAR 135 when the aircraft is needed for the business purposes of third parties (such as for other entities within the corporate group of the aircraft's owner).
