We study a variant of the Hasse principle for finite Galois modules, allowing exceptional sets of positive density. For a Galois module whose underlying abelian group is isomorphic to(), we show that the product of the restriction maps for places in a set of placesis injective if the Dirichlet density ofis strictly larger than. We give applications to the local–global divisibility problem for elliptic curves and the Hasse principle for flexes on plane cubic curves.
