In the future, minor damage could be detected and monitored during flight without the aircraft having to go into the hangar for maintenance. This will reduce operating costs and increase safety at the same time. The pressurized cabins of commercial aircraft, as well as their wings and tail units, are inspected for cracks and damage at regular intervals. Every six to ten years, each jet has to undergo a D-check in a hangar for one to two months. There, it is largely disassembled, even the paint is removed.
