Claim 9:
10. A propulsive assembly comprising a mast and an engine having a nacelle wrapping the engine and a propeller rotatable along an axis of rotation driven by the engine, the propulsive assembly comprising:
a standby protection device comprising a first connecting member fixedly mounted to the mast and a second connecting member fixedly mounted to the engine, the second connecting member being rotatably hinged with respect to the first connecting member with at least two degrees of freedom,
a retaining member fixes the first and second connecting members from relative movement with respect to one another in a fixed state of the retaining member and the retaining member is an unfixed state to release the at least two degrees of freedom of the standby protection device when a predetermined unbalance force on the propeller is reached; and
wherein the retaining member projects between the first and second connecting members in the fixed state and wherein the retaining member is biased by the predetermined unbalance force on the propeller or is broken by the predetermined unbalance force on the propeller in the unfixed state.
