To moor the aircraft, proceed as follows:
− Tow the aircraft to a parking area where there are tiedown anchors
available.
− Carry out the normal parking procedure.
− Install the tiedown rings (two), one in each primary brace strut of the
main landing gear.
− Attach a nylon rope to the tiedown ring with a bowline knot, and
then attach the other end of the rope to the tiedown anchor on the
ground by knotting it with a bowline knot. See the corresponding
illustration on the previous page.
