Not e: The i ntent was to highlight to the system designer that early coordination with an aircraft original equipment manufacturer (OEM) is important to minimize the compliance requirements at the time of installation, and that even without an OEM, the guidance is relevant when installing the system.
c. Guidance for the use of RTCA Documents DO-325 and DO-336.
(1) RTCA Document DO-325 identifies the typical functions of an AFGCS. We recommend that AFGCS equipment manufacturers obtain technical standard order authorization (TSOA) for TSO-C198 to minimize compliance showings that would be required at installation approval stage. There should be a declaration of any non-TSO functions in the TSOA application so there can be an appropriate evaluation and acceptance of the software and hardware qualification data related to those functions. If AFGCS equipment does not have TSOA for TSO-C198, the applicant for installation approval would have to show compliance with the DO-325 MOPS, as appropriate to functions provided, and conduct the necessary software and hardware qualifications defined in DO-178 and DO-254 guidance documents.
(2) RTCA Document DO-336 has two primary focus items: to highlight the requirements for a proper safety assessment (Chapter 8) and the compliance demonstration (Chapter 9). Each of these should be discussed with the appropriate Aircraft Certification Office (ACO) very early in the program and included in the certification plan.

APPENDIX A
INSTRUCTIONS FOR CONTINUED AIRWORTHINESS Instructions for Continued Airworthiness (ICA) are required by Federal Aviation Regulations (FAR)/Joint Airworthiness Regulations (JAR) § 29.1529. Appendix A to FAR/JAR Part 29 specifies the requirements for Instructions for Continued Airworthiness. The following 70 pages for this AC 29- 2C, Appendix A, provide a template for the ICA. This ICA Template was prepared to assist applicants in preparing an ICA for their type design change to rotorcraft.
The guidance is intended for applicants that are required to comply with FAR/JAR § 29.1529 to prepare Instructions for Continued Airworthiness acceptable to FAA/AUTHORITY.
The ICA Template contains requirements of Appendix A to FAR/JAR Part 29, identified by bold type. The bold type requirements are to be included in the applicant Instructions for Continued Airworthiness as applicable to the applicant’s type design change. Items in regular type are not required by FAR/JAR; however, these items are an aviation industry standard and are found in most current Instructions for Continued Airworthiness. The underlined words and sentences are to emphasize the information.
It is recommended the applicant include those in their ICA for standardization and clarity.
The ICA Template is arranged as a sample Instructions for Continued Airworthiness document and can be used as a template for the preparation of the applicant’s Instructions for Continued Airworthiness. The ICA Template was prepared to cover a complete rotorcraft. The applicant for a type design change need not include all information for the appropriate type design, only the applicable information to their type design change.
Appropriate text in regular type can be copied from the ICA Template. Text in italics and the appendices are for instructions and are not to be copied.
The ICA Template is formatted using the Airline Transport Association (ATA) Chapter numbering system. The ATA Chapter format is not required; however, it is recommended. The ATA chapter numbers that are not listed in this document do not relate to ICA’s and are not used in the ATA system for ICA’s (Maintenance Manual).
The Standard Practices chapters are broken out separately from the other listed chapters because they are not a requirement. However, Standard Practices are an industry standard and are found in most industry Maintenance Manuals.

INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (continued) The set of parentheses in the index and chapters indicates the chapter on the ICA Template that is applicable to various ATA chapters. The set of parentheses in Fi gure 1 and Figure 2 is used to indicate the applicability of the item for that type design change.
Instructions for Continued Airworthiness will be reviewed and evaluated by FAA/AUTHORITY to ascertain their acceptability.

LIST OF EFFECTIVE PAGES
a. The applicant should provide a means of identifying each page of the Instructions for Continued Airworthiness (ICA) so maintenance personnel know they have a complete and current ICA. There is no requirement for a specific format; however, there is an established standard format that has been used by industry for many years. This standard is the List of Effective Pages.
b. The applicant should list all pages, their revision number and revision date contained in the applicant’s ICA on a “List of Effective Pages” page either for the complete manual or by each chapter. If individual chapter method is used, the manual should have a master “List of Effective Pages” page containing all the chapters and their revision numbers.
c. A page means a single side of a leaf within the ICA. When no text is intended for a page the following statement should be on the blank page: THIS PAGE INTENTIONALLY LEFT BLANK. In addition the intentionally left blank page should contain the manual identification, revision number and page number. If a page has not been revised from the original issue, then this will always be designated with a revision number of “O.” It is a standard industry practice to list “Revision O” to indicate an original issue page. The revision number will remain the same until ICA is accepted by the FAA/AUTHORTY regardless of the number of draft changes made prior to acceptance.
d. The section that lists multiple chapters and has parentheses ( ) -00-00 indicates that the information is applicable to any of those chapters; i.e., Chapters 21, 33, 52, 67, or 71 of the ATA chapter format. The chapter numbers are not sequential because those missing chapters are not applicable to rotorcraft.
