G23.1
General. (a) This appendix specifies
requirements for the preparation of Instruc-
tions for Continued Airworthiness as re-
quired by § 23.1529.
(b) The Instructions for Continued Air-
worthiness for each airplane must include
the Instructions for Continued Airworthiness
for each engine and propeller (hereinafter
designated ‘products’), for each appliance re-
quired by this chapter, and any required in-
formation relating to the interface of those
appliances and products with the airplane. If
Instructions for Continued Airworthiness are
not supplied by the manufacturer of an ap-
pliance or product installed in the airplane,
the Instructions for Continued Airworthiness
for the airplane must include the informa-
tion essential to the continued airworthiness
of the airplane.
(c) The applicant must submit to the FAA
a program to show how changes to the In-
structions for Continued Airworthiness made
by the applicant or by the manufacturers of
products and appliances installed in the air-
plane will be distributed.
G23.2
Format. (a) The Instructions for
Continued Airworthiness must be in the
form of a manual or manuals as appropriate
for the quantity of data to be provided.
(b) The format of the manual or manuals
must provide for a practical arrangement.
G23.3
Content. The contents of the manual
or manuals must be prepared in the English
language. The Instructions for Continued
Airworthiness must contain the following
manuals or sections, as appropriate, and in-
formation:
(a)
Airplane maintenance manual or section.
(1) Introduction information that includes an
explanation of the airplane’s features and
data to the extent necessary for mainte-
nance or preventive maintenance.
(2) A description of the airplane and its
systems and installations including its en-
gines, propellers, and appliances.
(3) Basic control and operation information
describing how the airplane components and
systems are controlled and how they oper-
ate, including any special procedures and
limitations that apply.
(4) Servicing information that covers de-
tails regarding servicing points, capacities of
tanks, reservoirs, types of fluids to be used,
pressures applicable to the various systems,
location of access panels for inspection and
servicing, locations of lubrication points, lu-
bricants to be used, equipment required for
servicing, tow instructions and limitations,
mooring, jacking, and leveling information.
(b)
Maintenance instructions. (1) Scheduling
information for each part of the airplane and
its engines, auxiliary power units, propellers,
accessories, instruments, and equipment
that provides the recommended periods at
which they should be cleaned, inspected, ad-
justed, tested, and lubricated, and the degree
of inspection, the applicable wear tolerances,
and work recommended at these periods.
However, the applicant may refer to an ac-
cessory, instrument, or equipment manufac-
turer as the source of this information if the
applicant shows that the item has an excep-
tionally high degree of complexity requiring
specialized maintenance techniques, test
equipment, or expertise. The recommended
overhaul periods and necessary cross ref-
erence to the Airworthiness Limitations sec-
tion of the manual must also be included. In
addition, the applicant must include an in-
spection program that includes the fre-
quency and extent of the inspections nec-
essary to provide for the continued air-
worthiness of the airplane.
(2) Troubleshooting information describing
probable malfunctions, how to recognize
those malfunctions, and the remedial action
for those malfunctions.
(3) Information describing the order and
method of removing and replacing products
and parts with any necessary precautions to
be taken.
(4) Other general procedural instructions
including procedures for system testing dur-
ing ground running, symmetry checks,
weighing and determining the center of grav-
ity, lifting and shoring, and storage limita-
tions.
(c) Diagrams of structural access plates
and information needed to gain access for in-
spections when access plates are not pro-
vided.
(d) Details for the application of special in-
spection techniques including radiographic
and ultrasonic testing where such processes
are specified.
