SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. This AD was 
prompted by reports of chafing on the bottom panel of the center cabin. 
This AD requires a general visual inspection to determine if certain 
fasteners are installed, and related investigative and corrective 
actions. We are issuing this AD to detect and correct any chafing on 
the bottom panel of the center cabin, which could affect the structural 
integrity of the affected wing-to-fuselage connection.

DATES: This AD becomes effective February 13, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 13, 
2013.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

Engineer, International Branch, ANM-116, Transport Airplane

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 October 2, 2012 (77 
FR 60073). That NPRM proposed to correct an unsafe condition for the 
specified products. The Mandatory Continuing Airworthiness Information 
(MCAI) states:

    On two SAAB 2000 aeroplanes, signs of chafing have been found on 
the bottom panel of the centre cabin between fuselage station (STA) 
562 and STA 622. The investigation results have shown that the 
chafing is caused by certain Hi Lok fasteners, installed as a repair 
during production, through the upper wing skin panel.
    This condition, if not detected and corrected, could affect the 
structural integrity of the affected wing-to-fuselage connection.
    To address this potential unsafe condition, SAAB issued Service 
Bulletin (SB) 2000-53-057 to provide instructions for a general 
visual inspection to detect chafing in the area between the upper 
wing skin and the cabin centre bottom panel and to verify if there 
are Hi Lok fasteners installed with the collar up.
    For the reasons described above, this [European Aviation Safety 
Agency (EASA)] AD requires a one-time inspection of the designated 
area, the accomplishment of corrective action(s) [repair], depending 
on findings, and the reporting of all inspection results * * *.
    This [EASA] AD is considered an interim action and further AD 
action may follow.

    Related investigative actions include measuring the distance 
between the fastener and bottom panel and a boroscope inspection for 
chafing and damage of the bottom panel. You may obtain further 
information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 60073, October 2, 
2012) or on the determination of the cost to the public.

Conclusion

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

Costs of Compliance

    We estimate that this AD will affect 10 products of U.S. registry. 
We also estimate that it will take about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $3,400, or $340 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this AD.

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 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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (77 FR 60073, October 2, 
2012), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
