.... and the answer is :

FAR criteria require that landing gear design be based on:

-A sink rate of 10 feet per second at the maximum design landing weight; [...]


which equates to a touch-down vertical speed of 600 fpm !

However, in many AMM Ch 5 , the 'Overweight Landing' inspection is much reduced if the
vertical speed at touch-down is very low (FDR redout helps).
A high-vertical speed touch-down in overweight condition will surely make nasty damages to wing and/or LG
and/or other structure.
