## Discrepancy

DYNAMIC RELAY CONTROLS THE LANDING GEAR MOTOR.  THIS UNIT IS INCONSISTENT IN CONTROL OF MOTOR WHEN POWER TO THE RELAY CONTROL IS TURNED OFF BY THE ACTUATOR SWITCH ON THE GEAR BOX.  WHEN THIS HAPPENS THE GEAR BOX WILL BOTTOM OUT ON THE INTERNAL STOP INSIDE THE GEAR BOX.  WHNE THE RELAY FAILS, IT JAMS THE SECTOR GEAR IN THE GEAR BOX TO THE STOP.
