OK i know it's a little offtopic, but still fits to the "aircraft" section.

A friend of mine made a guided tour through an airport. And the guide told that the gear of modern passenger planes (Boings & Airbuses) are not able to withstand a landing of a fully loaded passenger plane.
The guide further explained that this is the reason why - in case of an emergency - the plane has to dump most of it fuel in the air.
I am a little bit supicious now.
I always thought the fuel dumping was due to the fire risk if a fully loaded jet has to make a "non-standard" landing.
I can not believe that the gear of modern jets is not lay out for the full take-off weight.
So can someone here answer this question:
Is the gear of modern passengers jets strong enough to withstand the landing forces of a fully loaded condition?
