Comments

    The proposed airworthiness design standards were offered for 
comment in Federal Register Volume 73, No. 14, Page 3655 on January 22, 
2008. No comments were received and the proposed airworthiness design 
standards were adopted.

Background

    The ``primary'' category for aircraft was created specifically for 
the simple, low performance personal aircraft. A means for applicants 
to propose airworthiness standards for their particular primary 
category aircraft is provided under 14 CFR, part 21, Sec.  21.17(f). 
The FAA procedure establishing appropriate airworthiness standards 
includes reviewing and possibly revising the applicant's proposal, 
publication of the submittal in the Federal Register for public review 
and comment, and addressing the comments. After all necessary 
revisions, the standards are published as approved FAA airworthiness 
standards.
    Accordingly, the FAA adopts the following airworthiness standards 
as final.

Citation

    The authority citation for these airworthiness standards is as 
follows:

    Authority: 49 U.S.C. 106(g), 40113 and 44701.

Final Airworthiness Standards for Acceptance of the Cubcrafters Model 
PC18-160 Under the Primary Category Rule

    The certification basis for the Cubcrafters, Inc., Model PC18-160 
is the Primary Category Rule (part 21, Sec.  21.24) with Amendment 23-
57 for 14 CFR, part 23, Sec. Sec.  23.853(a); 23.863; 23.1303(a), (b), 
and (c); 23.1311(a)(1) through (a)(4), and (b); 23.1321; 23.1322; 
23.1329 and 23.1359 and:

Airframe and Systems

    ASTM F2245-07, ``Standard Specification for Design and Performance 
of a Light Sport Airplane,'' modified as follows:
    1. Federal Aviation Regulations 23 Loads Report and Test Proposal 
to be reviewed and approved by the Seattle Aircraft Certification 
Office (ACO). Specifically, Section 5 of ASTM F2245-07 is replaced by 
Federal Aviation Regulations part 23, Sec. Sec.  23.301 through 23.561 
(latest amendments through Amendment 23-55) as applicable to this 
airplane.
    2. All major structural components will be tested as per the 
approved Test Proposal (this eliminates ``analysis'' allowed by ASTM).
    3. Paragraph 4.2.1 of ASTM F2245-07 is replaced by Federal Aviation 
Regulations part 23, Sec.  23.25(b) except that the empty weight 
referred to in Federal Aviation Regulations part 23, Sec.  23.25(b)(1) 
is replaced by the maximum empty weight defined in Paragraph 3.1.2 of 
ASTM F2245-07.

Engine

    The engine may or may not have its own type certificate. If the 
engine does not have its own type certificate, it will be included in 
the airplane type certificate using the following as a proposed 
certification basis:
    1. ASTM F2339-06, ``Standard Practice for Design and Manufacture of 
Reciprocating Spark Ignition Engines for Light Sport Aircraft,'' 
modified as follows: Engine parts and assemblies will be manufactured 
under the purview of a production certificate held by the applicant. 
Section 7 of ASTM F2339-06 does not apply.
    2. Optionally, the applicant may elect to use a type certificated 
engine up to 180 horsepower.

Propeller

    A type certificated propeller will be used.
    In addition to the applicable airworthiness regulations, the PC18-
160 must comply with the fuel vent and exhaust emission requirements of 
14 CFR part 34 and the noise certification requirements of 14 CFR part 
36; and the FAA must issue a finding of regulatory adequacy pursuant to 
Sec.  611 of Public Law 92-574, the ``Noise Control Act of 1972.''

    Issued in Kansas City, Missouri on April 9, 2008.
