Never underestimate the damage that can be caused by a point load at the
tip of a flight surface. I don't know about Cherokee stabilators and
girl point loads - but even a 1 mph tagging of a wingtip on a hangar can
bend spars on the inboard portion of the wing. Seemingly small point
loads on wingtips can cause all sorts of unseen damage. I believe
Highflyer has a story about a Taylorcraft spar and a compression
fracture he discovered in flight after a minor wingtip tagging incident.
Our club's C170 got a kinked aft spar after a minor wingtip tagging
incident.
