ACTION: Final rule. AGENCY: 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 hydraulic accumulator failure. This AD requires replacing certain hydraulic accumulators with stainless steel hydraulic accumulators, and structural modifications in the nose landing gear bay. We are issuing this AD to prevent failure of hydraulic accumulators, which may result in damage to the airplane and injury to occupants. SUMMARY: This AD becomes effective June 7, 2012. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 7, 2012.

That NPRM was published in the Federal Register on December 29, 2011 (76 FR 81889). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Three cases of failure have been reported, affecting the same type of hydraulic accumulator as installed on SAAB 2000 aeroplanes, although all occurred on other aeroplane types. The reported cause of these failures has been traced to corrosion. Any of the end parts on the accumulator may depart from the pressure vessel if they are affected by corrosion. This condition, if not detected and corrected, may lead to fatigue failure of a hydraulic accumulator, possibly resulting in damage to the aeroplane and injury to occupants. In addition, a quality issue during the replacement of the base material in the end parts of the accumulator may have affected the service life of the accumulator. To address this unsafe condition, SAAB has introduced a new type of hydraulic accumulator, which is made of stainless steel. For the reasons described above, this [EASA] AD requires the replacement of all Part Number (P/N) 08 8423 030 1 hydraulic accumulators with stainless steel P/N 40800– 2050 hydraulic accumulators and associated structural modifications in the nose landing gear bay. You may obtain further information by examining the MCAI in the AD docket. wreier-aviles on DSK7SPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Request To Include a Statement From the Service Information Saab AB (the commenter) requested that we revise the NPRM (76 FR 81889, December 29, 2011) to include a statement as follows: ‘‘In addition, a quality issue during the replacement of the base material in the end parts of the accumulator may have affected the service life of the accumulator.’’ We infer that the commenter requested that we add the statement to the Discussion section of the NPRM (76 VerDate Mar<15>2010 15:19 May 02, 2012 Jkt 226001 FR 81889, December 29, 2011). We agree that Saab Service Bulletin 2000–29–024, Revision 01, dated November 5, 2010, states, ‘‘In addition, a qualification issue during the change of the base material, for the end parts of the accumulator back in 1993, can have affected the life limit of the accumulator.’’ However, we have not included the statement in the final rule because we do not restate the Discussion section in the final rule. We have not changed the AD in this regard. Explanation of Additional Change Made to This AD We have revised the heading and wording in paragraph (i) of this AD; this change has not changed the intent of that paragraph. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously— except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (76 FR 81889, December 29, 2011) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 81889, December 29, 2011). Costs of Compliance We estimate that this AD will affect 8 products of U.S. registry. We also estimate that it will take about 12 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $9,995 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 parts. 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 to the U.S. operators to be $88,120, or $11,015 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, PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 26159 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 https:// www.regulations.gov; 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 (76 FR 81889, December 29, 2011), 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.

Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes

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

ACTION: Final rule.

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

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 hydraulic accumulator failure. This AD requires 
replacing certain hydraulic accumulators with stainless steel hydraulic 
accumulators, and structural modifications in the nose landing gear 
bay. We are issuing this AD to prevent failure of hydraulic 
accumulators, which may result in damage to the airplane and injury to 
occupants.

DATES: This AD becomes effective June 7, 2012.

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 December 29, 2011 
(76 FR 81889). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Three cases of failure have been reported, affecting the same 
type of hydraulic accumulator as installed on SAAB 2000 aeroplanes, 
although all occurred on other aeroplane types. The reported cause 
of these failures has been traced to corrosion. Any of the end parts 
on the accumulator may depart from the pressure vessel if they are 
affected by corrosion.
    This condition, if not detected and corrected, may lead to 
fatigue failure of a hydraulic accumulator, possibly resulting in 
damage to the aeroplane and injury to occupants. In addition, a 
quality issue during the replacement of the base material in the end 
parts of the accumulator may have affected the service life of the 
accumulator.
    To address this unsafe condition, SAAB has introduced a new type 
of hydraulic accumulator, which is made of stainless steel.
    For the reasons described above, this [EASA] AD requires the 
replacement of all Part Number (P/N) 08 8423 030 1 hydraulic 
accumulators with stainless steel P/N 40800-2050 hydraulic 
accumulators and associated structural modifications in the nose 
landing gear bay.

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 have considered the comment received.

Request To Include a Statement From the Service Information

    Saab AB (the commenter) requested that we revise the NPRM (76 FR 
81889, December 29, 2011) to include a statement as follows: ``In 
addition, a quality issue during the replacement of the base material 
in the end parts of the accumulator may have affected the service life 
of the accumulator.''
    We infer that the commenter requested that we add the statement to 
the Discussion section of the NPRM (76 FR 81889, December 29, 2011). We 
agree that Saab Service Bulletin 2000-29-024, Revision 01, dated 
November 5, 2010, states, ``In addition, a qualification issue during 
the change of the base material, for the end parts of the accumulator 
back in 1993, can have affected the life limit of the accumulator.'' 
However, we have not included the statement in the final rule because 
we do not restate the Discussion section in the final rule. We have not 
changed the AD in this regard.

Explanation of Additional Change Made to This AD

    We have revised the heading and wording in paragraph (i) of this 
AD; this change has not changed the intent of that paragraph.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously--except for minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 81889, December 29, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 81889, December 29, 2011).

Costs of Compliance

    We estimate that this AD will affect 8 products of U.S. registry. 
We also estimate that it will take about 12 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $9,995 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 parts. 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 to the 
U.S. operators to be $88,120, or $11,015 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 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
