CS 25.391Control surface loads: general
The control surfaces must be designed for the limit loads resulting from the flight conditions in CS 25.331, CS 25.341(a) and (b), CS 25.349 and CS 25.351, considering the requirements for:
(a)Loads parallel to hinge line, in CS 25.393;
(b)Pilot effort effects, in CS 25.397;
(c)Trim tab effects, in CS 25.407;
(d)Unsymmetrical loads, in CS 25.427; and
(e)Auxiliary aerodynamic surfaces, in CS 25.445.
