Sec. 27.301  Loads.

                                 General


    (a) Strength requirements are specified in terms of limit loads (the 
maximum loads to be expected in service) and ultimate loads (limit loads 
multiplied by prescribed factors of safety). Unless otherwise provided, 
prescribed loads are limit loads.
    (b) Unless otherwise provided, the specified air, ground, and water 
loads must be placed in equilibrium with inertia forces, considering 
each item of mass in the rotorcraft. These loads

must be distributed to closely approximate or conservatively represent 
actual conditions.
    (c) If deflections under load would significantly change the 
distribution of external or internal loads, this redistribution must be 
taken into account.
