On March 19, 2006, a Champion 7EC (registration N4387C) was involved in an aviation accident near Zellwood, FL. Investigators recorded the probable cause as: A loss of directional control due to the spring connecting the rudder to the tailwheel horn being detached.

After a normal approach and landing on runway 09, the aircraft began to swerve, left the runway, and entered a water-filled drainage ditch. Post-accident examination revealed the spring connecting the rudder to the tail wheel horn had detached.
