Let $$T^rM=J^r_0({\mathbb{R}},M)$$ be the $$r$$-th order tangent bundle of a manifold $$M$$. The author first constructs a map $$TP^2 M/G^2_m\to T^3M$$, where $$P^2M(M,G^2_m)$$ is the second order frame bundle of $$M$$. A second order connection is defined as a map $$T^2 M\to TP^2M/G^2_m$$ over the identity of $$TM$$. Such a connection is called stable or quasi-stable, if it projects into the identity of $$T^2M$$ or into the space of contact (1,2)-elements, respectively. Using these geometric ideas, the author solves a special type of the inverse variational problem in pseudo-Euclidean 3-space.
