INFORMATION CONTACT.

Comments Invited

    We invite interested parties to submit comments on the proposed 
airworthiness standards to the address specified above. Commenters must 
identify the Model PC18-160 and submit comments to the address 
specified above. The FAA will consider all communications received on 
or before the closing date before issuing the final acceptance. The 
proposed airworthiness design standards and comments received may be 
inspected at the FAA, Small Airplane Directorate, Aircraft 
Certification Service, Standards Office (ACE-110), 901 Locust Street, 
Room 301, Kansas City, MO 64106, between the hours of 7:30 a.m. and 4 
p.m. weekdays, except Federal holidays.

Background

    The ``primary'' category for aircraft was created specifically for 
the simple, low performance personal aircraft. Section 21.17(f) 
provides a means for applicants to propose airworthiness standards for 
their particular primary category aircraft. 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 applicant, Cubcrafters, Inc., has submitted a 
request to the FAA to include the following:

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 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

[[Page 3656]]

maximum empty weight defined in Paragraph 3.1.2 of ASTM F2245-07.

Engine

    The engine may not have its own type certificate; in such case 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.

Proposed Airworthiness Standards for Acceptance Under the Primary 
Category Rule

    The FAA is requiring use of the part 23 rules in addition to the 
Light Sport Airplane Consensus Standards. The applicant has agreed to 
this position; therefore, the certification basis for the Cubcrafters, 
Inc., Model PC18-160 will be 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 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 not have its own type certificate; in such case 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 
section 611 of Public Law 92-574, the ``Noise Control Act of 1972.''

    Issued in Kansas City, Missouri on January 11, 2008.

Acting Manager, Small Airplane Directorate, Aircraft Certification 
Service.
