HARDWARE AND AIRCRAFT REQUIREMENTS
2-1.
Grid Pattern Layout and Mooring Point
Strength. The grid pattern layout illustrating the 17 to
20 foot on center mooring points is depicted in figure
2-1.
a. This pattern readily accommodates all the heli-
copters in the army fleet and should be used as the stan-
dard for new mooring installations.
b. The strength of each mooring point should be
capable of reacting to the design loads depicted in fig-
ure 2-2.
2-2.
Mooring Pad Marking. Marking the moor-
ing pad to properly position the aircraft is recom-
mended if the pad is to be used exclusively for one type
of aircraft.
2-3.
General Tools and Equipment.
a. All aircraft will use polyester rope for rotor
blade tie-down. Refer to table 2-1.
(1) Tie-down OH-58D as specified in the ap-
propriate aircraft Technical Manual.
(2) Tie-down OH-58A/C as specified in the
appropriate Technical Manual, except that two main ro-
tor blade tie-down boots are required.
(3) Tie-down AH-64 as specified in the ap-
propriate Technical Manual. Ensure that the ropes are
strong enough to allow the main rotor blades to be se-
cured at the required locations.
(4) Tie-down UH-60 as specified in the ap-
propriate Technical Manual.
(5) Tie-down AH-1 as specifiated in the ap-
propriate Technical Manual.
(6) Tie-down UH-1 as specifiated in the ap-
propriate Technical Manual, except that a forward
main rotor blade tie-down strap is required.
(7) he-down CH-47 as specifed in the ap-
propriate Technical Manual.
b. Tie-down and Mooring Equipment. Refer to
table 2-1.
(1) Acquisition and maintenance of all re-
quired tie-down and mooring equipment is the re-
sponsibility of the aviation units.
(2) The identified chain and chain adjuster
shall be used as the primary mooring equipment for
all helicopters when parked at their home installation
and army policy (per paragraph 1 –6) requires moor-
ing. Exceptions to the use of mooring chains is only
approved under special circumstances where chain has
proven to be undesirable such as the crossover mooring
on the CH-47D.
(3) Mooring chains and chain adjusters are
not considered flyaway equipment. The 10,000
pound capacity polyester mooring strap with ratchet
buckle, NSN 5340-01-233-3063, is the identified fly-
away which may be used when aircraft deployed away
from their home station require mooring and chains are
not available. The CGU-lB, 5000 pound capacity ny-
lon tie-down strap, NSN 1670-00-725-1437, is only
authorized when hard stand mooring points
available and the field mooring kit is used.
