Civil Aviation Authority of China (CAAC)
European Aviation Safety Agency (EASA)
- EASA Safety/Special Emphasis Items (SEI)
- Small Airplane Standards Branch (SASB) Non-Basic Classification Criteria And Safety Emphasis Item (SEI) List (Effective March 22, 2019)
- Previous EASA SEI Lists and Cross Reference
- EASA Significant Standard Differences (SSD): As required by the FAA-EASA Technical Implementation Procedures (TIP), the current published FAA Significant Standards Differences (SSD) pairing lists for 14 CFR part 23 pairing to the European Aviation Safety Agency (EASA) CS-23 for products coming into the USA are listed below. If an amendment pairing is not shown here for your project, the Small Airplane Standards Branch will need to evaluate and develop a new SSD list and this will make the project Non-Basic per the FAA-EASA TIP Rev 6.
- SSD List Part 23-57 to CS 23 No Rev
- SSD List Part 23-58 to CS 23 No Rev
- SSD List Part 23-59 to CS 23 No Rev
- SSD List Part 23-59 to CS 23-2
- SSD List Part 23-61 to CS 23-2
- SSD List Part 23-62 to CS 23-3 Rev 3
- SSD List Part 23-62 to CS 23-4
- SSD List Part 23-64 to CS 23-5
Note 1: These amendment pairs have to be evaluated for both Basic and Non-Basic projects as required.
Note 2: As of February 12, 2018, the above SSD list with part 23-62 does not account for the amendment 23-62 errors yet. When the FAA Equivalent Level of Safety (ELOS) for the 23-62 errors is issued, there may be a few more SSDs introduced when compared to CS 23.
Note 3: The above SSD pairings do not include the additional EASA High Performance and General Certification Review Items (CRIs) which add additional EASA Special Conditions, Equivalent Safety Finding (ESFs), deviations, and method of compliance (MOC) that may introduce additional differences in certification requirements, which could become another set of SSDs. When these EASA additional CRIs are part of the incoming project, the Small Airplane Standards Branch will evaluate them to determine if they impact the FAA requirements and if a new set of SSDs are required.
National Agency for Civil Aviation in Brazil (ANAC)
- ANAC Non-Basic Classification Criteria and Safety Emphasis Items (SEI) List
United Kingdom Civil Aviation Authority (UK CAA)
- The above EASA Significant Standards Differences (SSD) lists also applies for the UK CAA, if the product is using the EASA CS regulations. If an amendment pairing using the EASA lists is not shown here for your project, the Small Airplane Standards Branch will need to evaluate and develop a new SSD list. Â If the product is using the English BCARs, contact the Small Airplane Standards Branch before applying for validation.
- At this time the Special Emphasis Items (SEI) list is not available for UK products/approvals seeking FAA Validation. Before application, contact the Small Airplane Standards Branch to determine if the SEI list developed for EASA can be used or if a new SEI list must be developed.
