General 

(a) This appendix specifies requirements 

for the preparation of Instructions for Con-
tinued Airworthiness as required by § 29.1529. 

(b) The Instructions for Continued Air-

worthiness for each rotorcraft must include 
the Instructions for Continued Airworthiness 
for each engine and rotor (hereinafter des-
ignated ‘‘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 rotorcraft. 
If Instructions for Continued Airworthiness 
are not supplied by the manufacturer of an 
appliance or product installed in the rotor-
craft, the Instructions for Continued Air-
worthiness 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 In-
structions 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 Air-

worthiness 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 Airworthi-
ness 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 mainte-
nance or preventive maintenance. 

(2) A description of the rotorcraft and its 

systems and installations including its en-
gines, rotors, and appliances. 

(3) Basic control and operation information 

describing how the rotorcraft components 
and systems are controlled and how they op-
erate, 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, 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, ro-
tors, accessories, instruments, and equip-
ment that provides the recommended periods 
at which they should be cleaned, inspected, 
adjusted, tested, and lubricated, and the de-
gree of inspection, the applicable wear toler-
ances, and work recommended at these peri-
ods. However, the applicant may refer to an 
accessory, instrument, or equipment manu-
facturer as the source of this information if 
the applicant shows that the item has an ex-
ceptionally high degree of complexity requir-
ing specialized maintenance techniques, test 
equipment, or expertise. The recommended 
overhaul periods and necessary cross ref-
erences to the Airworthiness Limitations 
section of the manual must also be included. 
In addition, the applicant must include an 
inspection program that includes the fre-
quency and extent of the inspections nec-
essary to provide for the continued air-
worthiness 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 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. 

(e) Information needed to apply protective 

treatments to the structure after inspection. 

(f) All data relative to structural fasteners 

such as identification, discard recommenda-
tions, and torque values. 

(g) A list of special tools needed. 

a29.4

Airworthiness Limitations Section 

The Instructions for Continued Airworthi-

ness must contain a section titled Airworthi-
ness Limitations that is segregated and 
clearly distinguishable from the rest of the 
document. This section must set forth each 
mandatory replacement time, structural in-
spection interval, and related structural in-
spection procedure required for type certifi-
cation. If the Instructions for Continued Air-
worthiness 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
