    a pivot plate coupled to the clevis bracket and operable to interface with the actuator arm to effectuate locking or unlocking the lock mechanism; and

    a pivot rod having a first end coupled to the pivot plate and a second end coupled to the lock mechanism, the pivot rod operable to actuate the locking bolt to lock or unlock the lock mechanism;

    wherein movement of the actuator arm in a first direction causes limited, responsive movement of the pivot plate to effectuate movement of the pivot rod in a second direction such that the pivot rod actuates the locking bolt to unlock the lock mechanism without moving the hatch to the open position, and continued movement of the actuator arm in the first direction moves the hatch from the closed position to the open position after the lock mechanism is unlocked.
