(b) The Instructions for Continued Airworthiness for each rotorcraft
must include the Instructions for Continued Airworthiness for each engine
and rotor (hereinafter designated "products"), for each applicance
required by this chapter, and any required information relating to the
interface of those appliances and products with the rotorcraft. If
Instructions for Continued Airworthiness are not supplied by the
manufacturer of an appliance or product installed in the rotorcraft, the
Instructions for Continued Airworthiness for the rotorcraft must include
the information essential to the continued airworthiness of the
rotorcraft.
(c) The applicant must submit to the FAA a program to show how changes
to the Instructions for Continued Airworthiness made by the applicant or
by the manufacturers of products and appliances installed in the
rotorcraft will be distributed.
(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.
A29.3 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 information:
(a) Rotorcraft maintenance manual or section. (1) Introduction
information that includes an explanation of the rotorcraft's features and
data to the extent necessary for maintenance or preventive maintenance.
(2) A description of the rotorcraft and its systems and installations
including its engines, rotors, and appliances.
(3) Basic control and operation information describing how the
rotorcraft components and systems are controlled and how they operate,
including any special procedures and limitations that apply.
(4) Servicing information that covers details 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, the lubricants
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 rotorcraft and its engines, auxiliary power units,
rotors, accessories, instruments, and equipment that provides the
recommended periods at which they should be cleaned, inspected, adjusted,
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 accessory, instrument, or equipment manufacturer as the
source of this information if the applicant shows that the item has an
exceptionally high degree of complexity requiring specialized maintenance
techniques, test equipment, or expertise. The recommended overhaul periods
and necessary cross references to the Airworthiness Limitations section of
the manual must also be included. In addition, the applicant must include
an inspection program that includes the frequency and extent of the
inspections necessary to provide for the continued airworthiness of the
rotorcraft.
(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 during ground running, symmetry checks, weighing and
determining the center of gravity, lifting and shoring, and storage
limitations.
(c) Diagrams of structural access plates and information needed to gain
access for inspections when access plates are not provided.
(d) Details for the application of special inspection techniques
including radiographic and ultrasonic testing where such processes are
specified.
(e) Information needed to apply protective treatments to the structure
after inspection.
(f) All data relative to structural fasteners such as identification,
discard recommendations, and torque values.
(g) A list of special tools needed.
A29.4 AIRWORTHINESS LIMITATIONS SECTION
The Instructions for Continued Airworthiness must contain a section
titled Airworthiness Limitations that is segregated and clearly
distinguishable from the rest of the document. This section must set forth
each mandatory replacement time, structural inspection interval, and
related structural inspection procedure approved under §29.571. If the
Instructions for Continued Airworthiness consist of multiple documents,
the section required by this paragraph must be included in the principal
manual. This section must contain a legible statement in a prominent
location that reads: "The Airworthiness Limitations section is FAA
approved and specifies maintenance required under §§43.16
and 91.403 of the Federal Aviation Regulations unless an alternative
program has been FAA approved."
