How often do commercial aircraft go in for maintenance?

The Frequency of Maintenance

Both factors that determine how often an aircraft needs to be serviced go hand-in-hand. Aircraft are constantly being inspected, repaired, maintained, and overhauled to provide the safest possible journey for passengers or cargo! The frequency of maintenance is dependent on the aircraft, as well as the requirements set forth by the aviation governing body (for instance, the FAA in the United States.)
