(a) Loads and equilibrium. For l imit ground loads:
(1) The limit ground l oads obt ained i n the l anding condi tions i n t his C S-29 m ust be considered to be exte rnal loads that would occur in the rotorcraft structure if it were acting as a rigid body; and
(2) In each specified landing condition, the external loads must be placed in equilibrium with l inear and angul ar i nertia loads in a rational or conservative manner.
(b) Critical centres of gravity. The critical centres of gravity within th e ran ge fo r wh ich certification is requested m ust be selected so that the m aximum design loads are obtained in each landing gear element.
