PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 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 2010–0184, dated September 6, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Corrosion damage has been found on the aft pressure bulkhead of SAAB 2000 aeroplanes, located on the rear side of the bulkhead at the bottom outboard flange. Corrosion damage in this area can become the starting point for future crack initiation and propagation. This condition, if not detected and corrected, could affect the structural integrity of the aft pressure bulkhead, possibly resulting in in-flight decompression of the fuselage and injury to occupants. For the reasons described above, this AD requires a detailed visual inspection of the aft pressure bulkhead at the bottom outboard flange [for corrosion and drain hole] and, depending on findings, corrective action. Corrective actions include contacting the FAA or EASA (or its delegated agent) for repair instructions if corrosion is found, and drilling a drain hole. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Saab AB, Saab Aerosystems has issued Service Bulletin 2000–53–048, Revision 01, dated September 3, 2009. 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 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 making E:\FR\FM\01JNP1.SGM 01JNP1 Federal Register / Vol. 76, No. 105 / Wednesday, June 1, 2011 / Proposed Rules these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect 8 products of U.S. registry. We also estimate that it would take 12 workhours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $8,160, or $1,020 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 proposed AD. We have no way of determining the number of products that may need these actions. 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. sroberts on DSK5SPTVN1PROD with PROPOSALS 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: VerDate Mar<15>2010 19:26 May 31, 2011 Jkt 223001 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); 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 proposed AD and placed it in the AD docket.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    Corrosion damage has been found on the aft pressure bulkhead of 
SAAB 2000 aeroplanes, located on the rear side of the bulkhead at 
the bottom outboard flange. Corrosion damage in this area can become 
the starting point for future crack initiation and propagation.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aft pressure bulkhead, possibly 
resulting in in-flight decompression of the fuselage and injury to 
occupants.
* * * * *
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by July 18, 2011.

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 2010-0184, dated September 6, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Corrosion damage has been found on the aft pressure bulkhead of 
SAAB 2000 aeroplanes, located on the rear side of the bulkhead at 
the bottom outboard flange. Corrosion damage in this area can become 
the starting point for future crack initiation and propagation.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aft pressure bulkhead, possibly 
resulting in in-flight decompression of the fuselage and injury to 
occupants.
    For the reasons described above, this AD requires a detailed 
visual inspection of the aft pressure bulkhead at the bottom 
outboard flange [for corrosion and drain hole] and, depending on 
findings, corrective action.

    Corrective actions include contacting the FAA or EASA (or its 
delegated agent) for repair instructions if corrosion is found, and 
drilling a drain hole. You may obtain further information by examining 
the MCAI in the AD docket.

Relevant Service Information

    Saab AB, Saab Aerosystems has issued Service Bulletin 2000-53-048, 
Revision 01, dated September 3, 2009. 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

    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 making

[[Page 31509]]

these changes, we do not intend to differ substantively from the 
information provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect 8 products of U.S. registry. We also estimate that it 
would take 12 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 $8,160, or $1,020 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 proposed 
AD. We have no way of determining the number of products that may need 
these actions.

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); 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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Saab AB, Saab Aerosystems: Docket No. FAA-2011-0476; Directorate 
Identifier 2010-NM-247-AD.

Comments Due Date

    (a) We must receive comments by July 18, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Saab AB, Saab Aerosystems Model SAAB 2000 
airplanes, all serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Corrosion damage has been found on the aft pressure bulkhead of 
SAAB 2000 aeroplanes, located on the rear side of the bulkhead at 
the bottom outboard flange. Corrosion damage in this area can become 
the starting point for future crack initiation and propagation.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aft pressure bulkhead, possibly 
resulting in in-flight decompression of the fuselage and injury to 
occupants.
