Narrative:

During climb after takeoff, the flight engineer noted a low 'a' system hydraulic light on and low quantity on gauge. As per aircraft operations manual, we declared an emergency, manually lowered the flaps and gear. We returned to airport and landed with no difficulties. Had the gear pinned and towed in. The mechanics told us that the flap actuator had a leak.
