A system to arrest flap over-travel employs a track engaging a flap to a support structure. The track has a deployment profile determining flap motion relative to the support structure during travel between an extended position and a normal retracted position. The deployment profile has a transition portion extending beyond the normal retracted position and terminating in a detent. A resiliently mounted catcher is configured to be displaced by the transition portion during over-travel of the flap beyond the normal retracted position and captured in the detent in a maximum retracted position thereby restraining the flap.
