Appendix A to Part 29 - Instructions for Continued Airworthiness
14:1.0.1.3.15.9.283.1.25 : Appendix A
Appendix A to Part 29 - Instructions for Continued Airworthiness
a29.1
General
(a) This appendix specifies requirements for the preparation of
Instructions for Continued Airworthiness as required by §
29.1529.
(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 appliance 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.
a29.2
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.
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
required for type certification. 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.”
