If cert ification for fl oat operat ion (including float amphibian operation) i s request ed, t he rotorcraft, with floats , m ust be designed to withstand the following loading conditions (where the limit load factor i s det ermined under C S 29.473 (b) or assumed t o be equal t o t hat determined for wheel landing gear):
(a) Up-load conditions in which:
(1) A lo ad is ap plied so that, with the rotorcraft in th e static lev el attitu de, th e resultant water reactio n passes vertically through the centre of gravity; and
(2) The vertical load prescribed in sub-paragraph (a)(1) i s applied simultaneously with an aft com ponent of 0.25 t imes t he vert ical component.
(b) A side load condition in which:
(1) A vertical load of 0.75 t imes t he total vertical lo ad sp ecified in su b-paragraph (a) (1) is divided equally among the floats; and (2) For each float, the load share determined under sub-paragraph (b)(1), combined with a to tal sid e lo ad o f 0.25 times the to tal v ertical lo ad specified in sub-paragraph (b)(1), is applied to that float only.
