ABSTRACT A structural assembly comprises first and second closure parts displaceable between a closed disposition in which they are locked by a locking mechanism and in which they close off the front side of the closure parts from the rear side and an open disposition in which they are spaced apart for access to the rear side of the closure parts and a default indicating device comprising a projection element which is movable to the rear side of the closure parts where it is stowed and which releases when the closure parts move to an open disposition and moves to a projecting position in which it projects from the rear side to the front side of the closure parts to provide a visual warning that the closure parts are not in the closed disposition. The closure parts in one embodiment are fan cowl doors of an aero engine nacelle which are hinged at their upper edges to the upper part of the nacelle and which have bottom edges which move into the closed disposition at the base of the nacelle. The projecting element in the projecting position then depends from the base of the nacelle.
