GENERAL.
These instructions are for use by the operator of the
AH-1F helicopter.

DESCRIPTION.
This manual contains the best operating instructions and
procedures for the AH-1F helicopter under most circumstances.
The observance of limitations, performance
and weight balance data provided is mandatory. The observance
of procedure is mandatory except when modification
is required because of multiple emergencies, adverse
weather, terrain, etc.

GENERAL DESCRIPTION.
The AH-1F helicopter is a tandem seat, two place (pilot
and gunner), single engine aerial weapon platform.

a. Fuselage. The fuselage (forward section) employs
aluminum alloy skins and aluminum, titanium and
fiberglass honeycomb panel construction. Honeycomb
deck panels and bulkheads attached to two main beams
produce a box-beam structure. These beams make up
the primary structure and provide support for the cockpit,
landing gear, wings, engine, pylon assembly, fuel cells,
and tailboom. The nose section incorporates the turret
system and telescopic sight unit.

b. Wing. The fixed cantilever wings have a span of
129 inches (including tip) and a mean chord of 30 inches.
The wings provide additional lift and support to the wing
stores pylon. Each wing has two pylons. The inboard pylons
are fixed and the outboard pylons are articulated by
hydraulic actuators. An ejector rack is attached to each
pylon. Both inboard and outboard pylons will each support
670 pounds of weight.

c. Tailboom. The tailboom (aft section) is a tapered
semimonocoque structure attached to the forward section
by four bolts. The tailboom supports the cambered
fin, tail skid, elevators, tail rotor and tail rotor drive system.

d. Main Rotor Blades.
(1) B540 The main rotor blades are metal,
bonded assemblies. Each blade is attached in the hub
with a retaining bolt assembly and is held in alignment by
adjustable drag braces.

(2) K747 The main rotor blades are glass fiber
epoxy resin bonded assemblies with a rubber erosion
guard. The skin is basket weave which will not be as
smooth as a metal blade. Each blade is attached in the
hub with a retaining bolt assembly and is held in alignment
by adjustable drag braces.
