The domestic air transport market is mainly serviced by airlines whose fleets are comprised primarily of leased aircraft owned by foreign lessors. According to Peruvian law, 'local' aircraft are those that are registered in the Peruvian public registry, while 'foreign' aircraft are those that are not. Foreign aircraft may operate in Peru while bearing foreign registration marks (eg, N, C or CC) or obtain provisional local registration marks, but this affects neither the legal definition of the aircraft as foreign nor the title to the assets. It is in the best interests of domestic operators, as lessees, that aircraft leases are duly and promptly recorded in the local public registry. This is a requirement for transferring the operator condition and for having the local aviation authority inspect the aircraft.
