Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. This proposed AD 
was prompted by reports of chafing on the bottom panel of the center 
cabin. This proposed AD would require doing a general visual inspection 
to determine if certain fasteners are installed, and related 
investigative and corrective actions. We are proposing 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: We must receive comments on this proposed AD by November 16, 
2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0068, dated April 25, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The 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 [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.

Relevant Service Information

    Saab AB, Saab Aerosystems has issued Service Bulletin 2000-53-057, 
dated November 22, 2011. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This AD and the MCAI or Service Information

    Saab Service Bulletin 2000-53-057, dated November 22, 2011, 
specifies to contact the manufacturer for repair instructions, but this 
proposed AD would require doing the repair using a method that we 
approve.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 10 products of U.S. registry. We also estimate that 
it would take about 4 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $3,400, or $340 per product.

[[Page 60074]]

    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

standards district office/certificate holding district office. The 
AMOC approval letter must specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: A federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5
