"the machines that have wings also collecting dust at EMA!"
Well, something was going to give sooner or later. If you take an aircraft that wasn't fit for the task in the first place and then load it up with role equipment so that it's always taking off/landing at the "Higher end" of its MAUW then at some point the landing gear will register a protest.
Papering (Welding) over the cracks will not save the structure.
It always was the wrong aircraft.
Buy cheap, buy twice.
