Maintenance and structure repairs are part of the normal upkeep of an aircraft. And this goes of course for the A350, with some slightly different methods due to composite primary structures. Today’s aircraft have been designed using the accumulated, past experience from previous passenger and cargo planes, enabling potential repairs to be identified and planned for in advance.
The choice of repair method will depend on the type of damage, level of severity and the material being repaired - be it aluminium, titanium or carbon. In some cases, solutions can be temporary, taking into account customer needs and constraints.
