Appendix A
Instructions for Continued Airworthiness

A529.1 General

  1. (a) This appendix specifies requirements for the preparation of Instructions for Continued Airworthiness as required by section 529.1529.
  2. (b) The Instructions for Continued Airworthiness for each rotorcraft shall include the Instructions for Continued Airworthiness for each engine and rotor (hereinafter designated ‘products’), for each appliance required by this Manual or CAR operating requirements 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 shall include the information essential to the continued airworthiness of the rotorcraft.
  3. (c) The applicant shall submit to the Minister a program to demonstrate 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.

A529.2 Format

  1. (a) The Instructions for Continued Airworthiness shall be in the form of a manual or manuals as appropriate for the quantity of data to be provided.
  2. (b) The format of the manual or manuals shall provide for a practical arrangement.

A529.3 Content

The Instructions for Continued Airworthiness shall contain the following manuals or sections, as appropriate, and the following information:

  1. (a) Rotorcraft maintenance manual or section. The rotorcraft maintenance manual or section shall contain the following information:
    1. (1) introduction information that includes an explanation of the rotorcraft’s features and data to the extent necessary for maintenance or preventive maintenance;
    2. (2) a description of the rotorcraft and its systems and installations including its engines, rotors, and appliances;
    3. (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. (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 levelling information.
  2. (b) Maintenance Instructions. The Maintenance Instructions shall contain the following information:
    1. (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 demonstrates that the item has an exceptionally high degree of complexity requiring specialized techniques, test equipment, or expertise. The recommended overhaul periods and necessary cross references to the Airworthiness Limitations section of the manual shall also be included. In addition, the applicant shall include an inspection program that includes the frequency and extent of the inspections necessary to provide for the continued airworthiness of the rotorcraft;
    2. (2) troubleshooting information describing probable malfunctions, how to recognize those malfunctions, and the remedial action for those malfunctions;
    3. (3) information describing the order and method of removing and replacing products and parts with any necessary precautions to be taken;
    4. (4) other general procedural instructions including procedures for system testing during ground running, symmetry checks, weighing and determining the centre of gravity, lifting and shoring, and storage limitations.
  3. (c) diagrams of structural access plates and information needed to gain access for inspections when access plates are not provided;
  4. (d) details for the application of special inspection techniques including radiographic and ultrasonic testing where such processes are specified;
  5. (e) information needed to apply protective treatments to the structure after inspection;
  6. (f) all data relative to structural fasteners such as identification, discard recommendations, and torque values;
  7. (g) a list of special tools needed.

A529.4 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:
(effective 2014/07/08)

“The Airworthiness Limitations section is approved by the Minister and specifies maintenance required by any applicable airworthiness or operating rule unless an alternative program has been approved by the Minister.”
