Is there any mechanism in engine mount to prevent shock loads on engine while landing?
&quot;Shock&quot; loads on landing can be transmitted to engine components.  The original poster appears to be asking about turbine engines specifically.  The significance of a hard landing on the engine spools themselves will be shaft flex and case flex, and the possibility of blade rubbing (and erosion).  This is a concern with a hard landing, and something that must be considered.  There are not &quot;shock absorbing&quot; features or capabilities built into bearings in engine spools; these are intended to have minimal friction in rotation, but no concentric movement about their axis.  It is possible in severe turbulence, and in a hard landing, to experience case or blade damage or wear, and there are inspections prescribed for certain components in certain engines to address this.
