Final rule.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of aileron and rudder control cables that may have tensions that are beyond allowable limits. This AD requires a revision to the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce functional tests of the control cable tension. We are issuing this AD to address the unsafe condition on these products.
