Here is an interesting fact for those that think control locks will hide damage caused by jet blast.
Control surfaces, hinges, mounts etc subjected to the same jet blast but left unsecured can also have hidden damage when you do your preflight!
Don't believe me? Well, Beechcraft communicated recently to owners and operators specifically about damage to the B200 rudder attach bolt (which cannot be seen unless you remove the rudder) due to jet blast slamming unsecured rudders against stops.
Control locks by nature are designed to take the force and prevent the forces being transmitted to the linkages and cables.
And for my money it's (don't do tail draggers personally so my comments do not relate to them) always parked into wind (well, as far as is practical). After all, the air was designed to go over the surfaces that way.
