Quite the question. As was stated, most need a check of some level. In fact all do. It may be an A, it may be a D, but it will need some form of thorough check.
I can say, from experience, that a certain AAirline (not a typo) will never let an airplane go from storage without, at least, new brakes and tires, no matter if it's been in storage 3 weeks or 3 years.
