FAA Issue Paper Significant Issues

FAA technical personnel work closely with the applicant to achieve the earliest feasible identification of significant issues that may require special emphasis for resolution. This step usually requires more detailed, technical discussions, correspondence, and review of design data and hardware. The following table describes significant issues which are addressed by issue papers. Reference FAA order 8110.112A.

Items Considered Significant Issues
(Types of Issue Papers)
Certification Basis (G-1)The G-1 IP designates the applicable airworthiness and environmental regulations (that is, noise, fuel venting and exhaust emissions), including equivalent level of safety (ELOS) findings and special conditions, that must be met for certification.
Determination of Compliance (G-2)The G-2 IP provides a statement of the FAA procedural requirements, including those that define the applicant’s responsibilities for showing compliance.
Environmental Consideration (G-3)The G-3 IP designates the applicable environmental regulations (that is, the regulations establishing standards for aircraft noise and, for turbine-engine-powered airplanes, fuel venting and exhaust emissions).
Export (Import) Country Requirements (G-4)For products exported from the United States, the G-4 IP cites the extent of FAA findings of compliance with the importing country’s airworthiness requirements on the importing civil airworthiness authority’s (CAA) behalf.
Method of Compliance (MoC)The most common type of IP defines a particular MoC that requires directorate or policy office coordination as a result of peculiarities in the type design or the need to define specific conditions and/or establish the environment under which substantiation must be shown.
Equivalent Level of Safety (ELOS)ELOS findings are made when literal compliance with an airworthiness standard cannot be shown and compensating factors exist that can be shown to provide an ELOS.
Proposed Special ConditionsUnder the provisions of either § 21.16 or § 21.101(d), a special condition is issued only if the existing applicable airworthiness standards do not contain adequate or appropriate safety standards for an aircraft, aircraft engine, or propeller because of novel or unusual design features of the product to be type certificated.
New InformationIt is conceivable that a better understanding of environmental or other hazards not understood in the past, or that did not exist previously, would require a new method of compliance.
Type ValidationWhen the FAA is the VA (Validating Authority), the FAA uses IPs to identify and resolve issues of particular interest to the FAA, including aspects of the design or proposed MoC that warrant further involvement (beyond familiarization) by the FAA.
Cover Issue Paper (CIP)A CIP is used to approve an IP from a foreign CA for the same program.
Administrative Collector Issue Paper (ACIP)An ACIP is an IP that approves previously approved FIPs or domestic IPs for a new certification program, provided that the current applicant is the same as the applicant of the previously approved IP or FIP.
Unsafe Features or CharacteristicsCorrective action of potentially unsafe features or characteristics that could preclude certification in accordance with § 21.21(b)(2). This type of issue paper is used to document the necessary corrective action.
Areas of New TechnologyAreas of new technology or novel design are those that do not require a special condition, but might require the development of an acceptable MoC with existing regulations that would set a national precedent.
Changes in InterpretationInclude new interpretation or policy of existing regulations using precedent-setting new technology in an IP at the early stages of the certification project.
Other Types of FAA Approvals (Optional)Applicants may use other types of FAA approvals (for example, PMA, TSOA, and § 21.8(d) projects) to document and resolve compliance issues where directorate or policy office guidance is required.
Administrative IPsAdministrative IPs may be used to define policy, interpret policy, or document the resolution of issues when adherence to policy becomes controversial or might otherwise require Type Certification Board (TCB) action to resolve.
Aircraft Evaluation Group (AEG) IPsThe AEG may initiate, at its discretion, IPs to address maintenance or operations issues that fall into one of the IP categories (except G-1 through G-4).
