You’ll Be Amazed By How Much Effort It Takes To Refurbish a 747-400 Jumbo Jet


Just like cars, airplanes have a comprehensive maintenance schedule that airlines must follow.  Maintenance is scheduled based on the number of cycles (takeoffs and landings) as well as additional inspections based on the age of a plane.

The 747-400 is no different.  Every 5 years a 747-400 has to undergo a ‘D-check’ inspection.  The inspection isn’t cheap.  They cost almost $3M as they strip the aircraft for a very thorough inspection and cleaning.
