AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an airworthiness authority 
of another country to identify and correct an unsafe condition on an 
aviation product. We are issuing this AD to require actions to correct 
the unsafe condition on these products.

DATES: This AD becomes effective September 18, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 18, 
2006.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street, SW., Nassif Building, 
Room PL-401, Washington, DC.

Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on June 6, 2006 (71 FR 
32492). That NPRM proposed to require an inspection of the internal 
surface of the elevator system final drive control rod and replacement 
if found corroded.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.
    The Modification and Replacement Parts Association (MARPA) provides 
comments to the MCAI AD process pertaining to how the FAA addresses 
parts manufacturer approval (PMA) parts. The commenter would like to 
see the FAA more fully address the intent of the AD as it affects PMA 
alternatives to the unsafe Original Equipment Manufacturer (OEM) part.
    We acknowledge the need to ensure that unsafe PMA parts are 
identified and addressed in MCAI-related ADs. We are currently 
examining all aspects of this issue, including input from industry. 
Once we have made a final determination, we will consider how our 
policy regarding PMA parts in ADs needs to be revised. We consider that 
to delay this AD action would be inappropriate since we have determined 
that an unsafe condition exists and that replacement of certain parts 
must be accomplished to ensure continued safety.
    We have not changed the final rule AD action based on this comment.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable in a U.S. court of 
law. In making these changes, we do not intend to differ substantively 
from the information provided in the MCAI and related service 
information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are described in a separate paragraph of the AD. These requirements, if 
any, take precedence over the actions copied from the MCAI.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 91 products of U.S. registry. We also estimate that it 
will take about 5 work-hours per product to do the action and that the 
average labor rate is $80 per work-hour. Required parts will cost about 
$1,000 per product. Where the service information lists required parts 
costs that are covered under warranty, we have assumed that there will 
be no charge for these costs. As we do not control warranty coverage 
for affected parties, some parties may incur costs higher than 
estimated here. Based on these figures, we estimate the cost of this AD 
on U.S. operators to be $127,400, or $1,400 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between

[[Page 46396]]

the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains the NPRM, the regulatory evaluation, any comments 
received, and other information. The street address for the Docket 
Office (telephone (800) 647-5227) is in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.
