Hello Peter,

I agree with the advice that you've received from Scott and Bob. There is no 
structural problem mounting the heated pitot tube as per the plans. Forget 
about a heated static port, it's absoutely unnecessary. I have demonstrated 
sufficient personal stupidity to get myself into severe icing conditions in 
our 320. Several inches of ice on everything that faced forward, but nothing 
on the static ports. (fuselage static ports constructed per the plans).
