SUPPLEMENTARY INFORMATION:
Background
ICON applied to the FAA on August 3, 2020, for a primary category
type certificate (TC) under 14 CFR 21.17(f) for the Model A5-B
airplanes.
The ICON Model A5-B airplane consists of a Rotax 912 iS Sport
piston engine certified by European Union Aviation Safety Agency (EASA
TC E.121) with additional FAA validation requirements to account for
differences between EASA CS-E requirements and FAA 14 CFR part 33
requirements. The ICON A5-B will utilize a Sensenich 3-blade composite
propeller that conforms with the ASTM consensus standard for propellers
identified in Tables 1 and 3 of these airworthiness design criteria.
The FAA does not plan to issue TCs for the engine or the propeller.
For continued operational safety (COS) requirements, the applicant
would need to utilize the processes outlined in ASTM F3198-18
identified in Tables 1 and 7 of these airworthiness design criteria to
develop a COS program. Some differences exist between FAA processes for
COS for primary category aircraft and those outlined for LSA in ASTM
F3198-18. The operational safety risk assessment information in the
appendix of ASTM F3198-18 would need to be utilized by the TC holder,
except notification to the FAA is required for reportable events
identified in Sec. 21.3. The FAA will then utilize a risk assessment
process in determining if mandatory action is required.
Under Sec. 21.17(c), an application for type certification is
effective for three years, unless the FAA approves a longer period.
Section 21.17(d) provides that, where a TC has not been issued within
the time limit established under Sec. 21.17(c), the applicant may file
for an extension and update the designated applicable regulations in
the type certification basis. The effective date of the applicable
airworthiness requirements for the updated type certification basis
must not be earlier than 3 years before the date of issue of the type
certificate. Since the project was not certificated within 3 years
after the application date above, the FAA approved the applicant's
request to extend the application for type certification. As a result,
the extended date of application for type certification is September
26, 2022.
The FAA issued a notice of proposed airworthiness criteria for the
ICON Model A5-B airplane, which published in the Federal Register on
August 31, 2023 (88 FR 60153).
Discussion of Comments
The FAA received no comments.
Applicability
These airworthiness criteria, established under the provisions of
Sec. 21.17(f), are applicable to the ICON Model A5-B airplane. Should
ICON apply at a later date for a change to the type certificate to
include another model, these airworthiness criteria would apply to that
model as well, provided the FAA finds them appropriate in accordance
with the requirements of subpart D to part 21.
Conclusion
This action affects only the airworthiness criteria for one model.
It is not a standard of general applicability.
Authority Citation
The authority citation for these airworthiness criteria is as
follows:
Authority: 49 U.S.C. 106(f), 106(g), 40113, 44701, 44702, and
44704.
Airworthiness Criteria
Pursuant to the authority delegated to me by the Administrator, the
following airworthiness criteria are issued as part of the type
certification basis for the ICON Model A5-B airplane. The FAA finds
that compliance with the following would mitigate the risks associated
with the proposed design and would provide an equivalent level of
safety to existing rules.
The airworthiness criteria for the issuance of a TC for the ICON
Aircraft, Inc., Model A5-B airplane, a primary category airplane, and
its powerplant installation is listed in Tables 1 through 8 below.
The following certification basis, established under the provisions
of Sec. 21.17(f), is appropriate for the ICON Model A5-B airplane:
