CAUTIONDo not use a clevis assembly (G-13) to attach the anchor line cable to the aircraft. If the cable is loose, the clevis may rotate sideways and drastically reduce the strength of the anchor line cable.Place a four-by-four-by-six-inch wooden block between the anchor line cable and floor and attach a clevis assembly (G-13) to the tie-down ring at station No. 502 for use as a USLM snap hook stop.Remove excess slack from the anchor line.Turn over and secure the conveyor rollers on the ramp in the down position with the smooth surface up or remove.Ensure drive-on aids are removed.Ensure the tail skid is in the “up” position before the jumpers exit the aircraft.
