INTRODUCTION.
a. This manual contains instructions for accomplishing Nondestructive Inspection (NDI) of the CH/MH-47
helicopters at the AVUM and AVIM levels. The procedures described in this manual are intended to provide instructions
for the NDI of locations where service defects would prevent items from performing their designated functions, and of
components for serviceability. These procedures were developed through review of CH/MH-47 Technical Manual
inspection requirements. The goal is to upgrade these requirements wherever possible using NDI methodology to
improve inspection quality, decrease inspection time, and increase systems operational readiness. Other factors
involved were maintenance engineering analysis, experience, and comparison with similar installations. Procedures
shall be reviewed and changes and additions made during the service life of the equipment by continually evaluating the
following: performance of the equipment, results of scheduled inspections, and thorough study of failure data. Local
conditions, such as special utilization or climatic environment, may dictate more detailed inspections. Commanders and
their maintenance officers are expected to exercise their prerogative to increase the frequency and scope of any
inspection as required.

b. This manual may pertain to part, or all types and series, of a model, and may, therefore, contain requirements
applicable to specific equipment that is not installed on an individual model. ... Read more

INTRODUCTION.
SECTION I
INTRODUCTION
a. This manual contains instructions for accomplishing Nondestructive Inspection (NDI) of the
OH-58A/C helicopter at the AVUM and AVIM levels. The procedures described in this manual are
intended to provide instructions for the NDI of locations where service defects would prevent items
from performing their designated functions, and of components for serviceability. These procedures
were developed through review of OH-58A/C Technical Manual inspection requirements. The goal
is to upgrade these requirements wherever possible using NDI methodology to improve inspection
quality, decrease inspection time and increase systems operational readiness. Other factors involved
were maintenance engineering analysis, experience and comparison with similar installations.
Procedures shall be reviewed and changes and additions made during the service life of the
equipment by continually evaluating the following: performance of the equipment, results of
scheduled inspections, and thorough study of failure data. Local conditions, such as special utilization
or climatic environment, may dictate more detailed inspections. Commanders and their maintenance
officers are expected to exercise their prerogative to increase the frequency and scope of any
inspection as required.
b. This manual may pertain to part, or all types and series, of a model, and may, therefore,
contain requirements applicable to specific equipment that is not installed on an individual model.
When this situation is encountered, those requirements that are not applicable should be
disregarded.
c. This manual does not contain inspection level or frequency, acceptance and rejection
limitations, or instructions for correcting defective conditions. Inspection levels and frequency are
provided in the inspection requirements manuals. Detailed acceptance and rejection criteria and
instructions for correcting defective conditions are provided in appropriate maintenance manuals and
are therefore not contained in this manual. Decision regarding the serviceability of components
properly belongs with maintenance technicians trained, skilled, and experienced in their particular
specialty, such as airframe, hydraulic, or propulsion. Also, it would duplicate existing information and
make the task of incorporating the numerous changes to inspection frequency and repair instructions
impractical.
d. The inspection requirements are stated in such a manner as to address the following: (1)
What part or area is to be inspected? (2) What conditions are to be sought? (3) What NDI method
is to be used? (4) How is the method to be performed? In scope, the inspection procedures are
designed to direct attention of maintenance personnel to components and areas where service
defects can occur. The procedures also provide detailed instructions on the application of NDI in an
effort to ensure the serviceability of these areas.
e. Nondestructive inspection methods require application by trained, experienced, and
proficient technicians. This manual provides detailed procedures for the application of nondestructive
methods to inspect specific areas or locations. However, it must be emphasized that the reliability of
the inspection depends upon the proper evaluation of the results obtained from the inspection
equipment.
f. While using this manual, such adjectives as left and right, upper and lower, front and rear,
forward and aft, and clockwise and counterclockwise refer to the helicopter as viewed from the rear
(aft), looking forward. ... Read more

Product Description
US Army Technical Manual, OPERATORS MANUAL FOR, ARMY MODEL, AH-1F ATTACK HELICOPTER, TM 1-1520-236-10, 2001

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. ... Read more
