Electric trim certification is addressed in CS 23 including the runaway conditions and associated disconnect switches. Any trim interrupt/disconnect switch is considered a safety system control and the function and operation should be described in the POH or AFM. Electric trim systems are not referred to in Section S or CS VLA.
