Well, some things go soft with age...
There was an EMS AS365N1 here in Sweden with lots of hours on it, previously oil-work, that had gone soft in the main cabin structure, which made the doors very difficult to close in flight. On ground with weight on wheels, no problem. In the air with everything hanging in the main rotor, doors jammed if opened.
But it did it's job until replaced and I think it's in France being rebuilt now.
