Section 14  Aircraft Evaluation Group Personnel Evaluating the Acceptability of Instructions for Continued Airworthiness

8-5-14-1    PURPOSE. This section provides guidance on determining project involvement through the instructions for continued airworthiness (ICA) review and acceptance process. The Flight Standards Aircraft Evaluation Group (AEG), Aviation Safety Inspector (ASI), involvement begins during the type certification process. After reviewing ICAs, the AEG ASI should be able to confirm if compliance has been shown with current policies, procedures, and technical criteria to enable operators to maintain aeronautical products and articles in an airworthy condition.

A.    Processes Related to ICAs. The AEG ASI may review the ICAs to determine their acceptability. This review may require references to the following related processes or documents as applicable to the project being worked.

B.    Applicable Processes and Documents.

1)    Type certificates (TC) and changes to type design, with or without amendment of the certificate, regardless of process of approval;
2)    Supplemental Type Certificate (STC) and changes to STC type design, with or without amendment to the certificate, regardless of the process of approval;
3)    Parts Manufacturer Approvals (PMA);
4)    Technical Standard Order Authorizations (TSOA) and Technical Standard Order (TSO) letter of design approvals (LODA);
5)    Maintenance Review Board Report (MRBR) or Maintenance Type Board Report (MTBR) tasks;
6)    Revisions of ICAs;
7)    Special Airworthiness Information Bulletins (SAIB);
8)    Airworthiness Directives (AD);
9)    Alternative methods of compliance (AMOC) to ADs;
10)    Certification Maintenance Requirements (CMR);
11)    Electrical wiring interconnection systems (EWIS) ICAs;
12)    ICA impact assessments;
13)    Airworthiness Limitations Section (ALS) ICAs;
14)    Issue Papers (IP) related to the project; and
15)    All applicable aging aircraft maintenance requirements as necessary.

8-5-14-3    BACKGROUND.

A.    Responsibilities. The FAA established the AEGs to determine the operational and maintenance suitability of an aircraft, thereby ensuring that the aircraft certificated through AIR procedures would be able to be operated and maintained in the field. AEG members oversee continued airworthiness and operational aspects of an aircraft throughout its operational life. The responsibilities of the AEG were established as part of the Flight Standards Service (AFS) organization, and the current edition of FAA Order 8430.21, Flight Standards Division, Aircraft Certification Division, and Aircraft Evaluation Group Responsibilities details those responsibilities. The AEG ASI can determine the operational suitability and continuing airworthiness requirements of both newly certified and modified aeronautical products and articles intended for operation under the Code of Federal Regulations (CFR).

B.    Qualifications. Aviation safety inspectors (ASI) assigned by AEG management are qualified, knowledgeable, and experienced in evaluating continued airworthiness programs as described in Order 8430.21. When the AEG ASI reviews ICAs for maintenance suitability during the type certification process, the AEG ASI must also have knowledge of the product being reviewed. This review helps the AEG ASI confirm compliance with applicable regulatory standards. This review also helps the AEG ASI make appropriate recommendations, reduce the chance of misinterpretation of any maintenance instructions, and ultimately ensure the continued airworthiness of the product.


A.    Definition. ICAs are instructions and information related to the continued airworthiness of aircraft, aircraft engines, propellers, and articles. A design approval holder (DAH) must develop and/or reference ICAs per Title 14 of the Code of Federal Regulations (14 CFR) part 21, § 21.50(b).

B.    Examples. An ICA may include, but is not limited to:

·    Aircraft Maintenance Manual (AMM);

·    Overhaul Manual (OHM);

·    Wiring Diagram Manual (WDM);

2)    Establish the project record as per AFS-AEG-005 and local office procedures.
3)    Determine if the project requires development of an FAA issue paper. (Refer to Orders 8110.4 and 8110.112, Standardized Procedures for Usage of Issue Papers and Development of Equivalent Levels of Safety Memorandums.) If it does, develop an IP as per local office procedures and coordinate with the ACO as appropriate.
4)    Respond to the CPN with AEG comments about project involvement and request any additional data necessary, such as sending an ICA or, if applicable, routing issue papers for coordination per the local AEG office procedure.

B.    Conduct the Review. For new TC/STC projects, either the ACO or applicant should submit full ICA documentation. For existing TC/STC projects, either the ACO or the applicant should send you a statement validating the impact assessment or confirming that the existing ICA is unchanged. You should then conduct the following steps if applicable:

1)    Review the ICA or its impact assessment per the applicable 14 CFR part, and also the requirements in Order 8110.54 to plan and determine acceptability.
2)    Review the applicant’s program for how ICA changes will be submitted and distributed.
3)    Check for any continued operational safety (COS) issues, such as in-service problems, ADs, AMOCs or SAIBs. These COS items could affect the ICA review.
4)    Update the project record through local office procedures.

C.    Review All Sections of the ICA.

1)    Review all sections of the proposed ICA for the outlined parts, orders, and certification requirements, including:

·    Title 14 CFR part 33, appendix A;

·    Title 14 CFR part 35, appendix A; and

·    FAA Order 8110.54.

2)    Determine if the EWIS ICA (if applicable) has been approved by the appropriate FAA Oversight Office.
3)    Document any missing or incorrect ICA information for all installed systems.
4)    Notify the ACO of any major discrepancies.

D.    Review the ALS.

NOTE:  The responsible ACO approves the ALS and the FAA Oversight Office approves the EWIS ICA.

1)    Verify that the ALS:
a)    Is properly titled, segregated, and clearly distinguishable;
b)    Is located in the principal manual when the ICA consists of multiple documents; and
c)    Documents, as applicable, the following items required for type certification:

·    Each mandatory replacement time,

·    Each required inspection interval and related required inspection procedure, and

·    Each mandatory replacement time of EWIS components as defined in part 25, § 25.1701.

2)    Verify that the ALS contains the required statement shown in the applicable 14 CFR appendix listed below for the applicable 14 CFR part:

·    Part 23 appendix G, § G23.4,

·    Part 25 appendix H, § H25.4,

·    Part 27 appendix A, § A27.4,
