l-g,
737s,767s and 777s are also certified to land at MTOW, with just an inspection required (Don't know about 747, can anyone enlighten?)
I believe that the A380 has a three stage deal where, as you say, it can land at MTOW, but requires an inspection. It has another weight, greater than MLW but less than MTOW at which it can land and not require an inspection because of the un-jettisonable fuel as you mention.
Musta, quite true!!
