ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. This AD was prompted by hydraulic pipe ruptures in the center of the cabin resulting in passengers being contaminated with hydraulic fluid. This AD requires installing a hydraulic fluid containment system. We are issuing this AD to prevent harmful or hazardous concentrations of hydraulic fluid or hydraulic vapor from entering the passenger compartment, possibly resulting in injury to the passengers. DATES: This AD becomes effective December 5, 2012. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 5, 2012. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the SUMMARY: PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 65801 U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC.

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 21, 2012 (77 FR 37340). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) states: Cases of hydraulic pipe ruptures in the centre of the cabin of BAe 146 aeroplanes have been reported, which have resulted in the passengers being contaminated with hydraulic fluid. The results of the investigations have shown that the pipe failures were caused by a combination of seam welded pipes, bends in the pipe runs with small bend radii and fatigue damage due to pressure variations. This condition, if not corrected, could lead to harmful or hazardous concentrations of hydraulic fluid or hydraulic vapour entering the passenger compartment, possibly resulting in injury to the occupants. For the reasons described above, this [European Aviation Safety Agency] AD requires the installation of a flexible envelope around the hydraulic pipe group where the failures have occurred to capture and contain any fluid escaping from a burst pipe and channel it below floor level into the forward cargo 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 considered the comment received. Request for Exclusion of Airtankers Neptune Aviation Services requested a change in the text of paragraph (c) ‘‘Applicability,’’ of the NPRM (77 FR 37340, June 21, 2012) to include an ‘‘exemption’’ for an airplane operated as an ‘‘airtanker,’’ which does not carry passengers. We partially agree with the request to change the text in paragraph (c) of this AD. We disagree with using the term ‘‘airtanker’’; however, we have revised E:\FR\FM\31OCR1.SGM 31OCR1 65802 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations paragraph (c) to include an exception for airplanes in a non-passenger configuration. 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 changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 37340, June 21, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 37340, June 21, 2012). mstockstill on DSK4VPTVN1PROD with RULES Costs of Compliance We estimate that this AD will affect 1 product of U.S. registry. We also estimate that it will take about 8 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 $5,079 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 $5,759. 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 VerDate Mar<15>2010 16:49 Oct 30, 2012 Jkt 229001 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 http:// 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 (77 FR 37340, June 21, 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.

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 series airplanes and 
Model Avro 146-RJ series airplanes. This AD was prompted by hydraulic 
pipe ruptures in the center of the cabin resulting in passengers being 
contaminated with hydraulic fluid. This AD requires installing a 
hydraulic fluid containment system. We are issuing this AD to prevent 
harmful or hazardous concentrations of hydraulic fluid or hydraulic 
vapor from entering the passenger compartment, possibly resulting in 
injury to the passengers.

DATES: This AD becomes effective December 5, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 5, 
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 June 21, 2012 (77 FR 
37340). That NPRM proposed to correct an unsafe condition for the 
specified products. The Mandatory Continuing Airworthiness Information 
(MCAI) states:

    Cases of hydraulic pipe ruptures in the centre of the cabin of 
BAe 146 aeroplanes have been reported, which have resulted in the 
passengers being contaminated with hydraulic fluid. The results of 
the investigations have shown that the pipe failures were caused by 
a combination of seam welded pipes, bends in the pipe runs with 
small bend radii and fatigue damage due to pressure variations.
    This condition, if not corrected, could lead to harmful or 
hazardous concentrations of hydraulic fluid or hydraulic vapour 
entering the passenger compartment, possibly resulting in injury to 
the occupants.
    For the reasons described above, this [European Aviation Safety 
Agency] AD requires the installation of a flexible envelope around 
the hydraulic pipe group where the failures have occurred to capture 
and contain any fluid escaping from a burst pipe and channel it 
below floor level into the forward cargo 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 considered the comment received.

Request for Exclusion of Airtankers

    Neptune Aviation Services requested a change in the text of 
paragraph (c) ``Applicability,'' of the NPRM (77 FR 37340, June 21, 
2012) to include an ``exemption'' for an airplane operated as an 
``airtanker,'' which does not carry passengers.
    We partially agree with the request to change the text in paragraph 
(c) of this AD. We disagree with using the term ``airtanker''; however, 
we have revised

[[Page 65802]]

paragraph (c) to include an exception for airplanes in a non-passenger 
configuration.

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 changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 37340, June 21, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 37340, June 21, 2012).

Costs of Compliance

    We estimate that this AD will affect 1 product of U.S. registry. We 
also estimate that it will take about 8 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 $5,079 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 $5,759.

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

fluid. We are issuing this AD to prevent harmful or hazardous 
concentrations of hydraulic fluid or hydraulic vapor from entering 
the passenger compartment, possibly resulting in injury to the 
passengers.

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.
