SUPPLEMENTARY INFORMATION: Discussion On January 11, 2015, we issued AD 2015–02–06, Amendment 39–18073 (80 FR 5017, January 30, 2015). AD 2015– 02–06 applied to certain Bombardier, Inc. Model CL–600–2B16 (CL–604 Variant) airplanes. AD 2015–02–06 was prompted by reports of loose, broken, or backed-out spur gear bolts on the HSTA. AD 2015–02–06 required a revision to the airplane flight manual, a revision to the maintenance or inspection program, as applicable, and replacement of HSTAs having certain part numbers. We issued AD 2015–02–06 to detect and correct loose spur gear bolts on the HSTA, which, if combined with the failure of the primary load path, could lead to failure of the HSTA and subsequent loss of the airplane. Since we issued AD 2015–02–06, Amendment 39–18073 (80 FR 5017, January 30, 2015), three typographical errors were discovered in AD 2015–02– 06. As published, a digit was missing from the engineer’s phone number in the FOR FURTHER INFORMATION CONTACT section of the preamble of AD 2015–02– 06, Amendment 39–18073 (80 FR 5017, January 30, 2015). The correct phone number is ‘‘516–228–7331.’’ As published, the AD number of AD 2015–02–06, Amendment 39–18073 (80 FR 5017, January 30, 2015), appears as ‘‘2014–02–06’’ in the Product Identification line of the regulatory text of the AD. The correct AD number is ‘‘2015–02–06.’’ The AD number is referenced correctly throughout the remainder of that document. As published, a vendor part number in paragraph (j) of AD 2015–02–06, Amendment 39–18073 (80 FR 5017, January 30, 2015), was incorrectly identified as ‘‘845401.’’ The correct vendor part number is ‘‘8454–1.’’ Since this new AD replaces AD 2015– 02–06, Amendment 39–18073 (80 FR 5017, January 30, 2015), there are no additional changes in this new AD. VerDate Sep<11>2014 14:05 Mar 13, 2015 Jkt 235001 FAA’s Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of the urgency to correct the part number and AD number errors to avoid non-compliance. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2015–0491; Directorate Identifier 2015–NM–019– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 125 airplanes of U.S. registry. The actions required by AD 2015–02– 06, Amendment 39–18073 (80 FR 5017, January 30, 2015), and retained in this AD take about 21 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 about $0 per product. Based on these figures, the estimated cost of the actions that are required by AD 2015–02–06 is $1,785 per product. The new requirements of this AD add no additional economic burden. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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.

ACTION: Final rule. AGENCY: (o) Material Incorporated by Reference [FR Doc. 2015–05735 Filed 3–13–15; 8:45 am] Federal Aviation Administration We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 757–200, –200PF, –200CB, and –300 series airplanes; and Model 767–200, –300, –300F, and –400ER series airplanes. This AD was prompted by reports indicating that the counterweights in some hub assemblies of the ram air turbine (RAT) could be understrength and fracture when the RAT is rotating, and that some RAT hub assemblies were delivered with balance washer retention screws that were incorrectly heattreated, and therefore, susceptible to fracture and cracking. This AD requires a part number and serial number inspection to determine if certain RAT hub assemblies are installed; and, for affected RAT hub assemblies, doing an inspection for missing and fractured balance washer screws, and replacement or rework if necessary. We are issuing this AD to prevent an inoperative RAT, which, following a dual engine shutdown in flight, will cause loss of all hydraulic power to the primary flight controls, resulting in subsequent loss of control of the airplane. DATES: This AD is effective April 20, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 20, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model 757–200, –200PF, –200CB, and –300 series airplanes; and Model 767–200, –300, –300F, and –400ER series airplanes. The SNPRM published in the Federal Register on April 24, 2014 (79 FR 22777). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on May 20, 2008 (73 FR 29087). The NPRM proposed to require doing an inspection to determine the part number and serial number of the RAT hub assembly, and replacing the RAT hub assembly with a new, serviceable, or reworked and reidentified RAT hub assembly if necessary. The NPRM was prompted by reports indicating that the counterweights in some hub assemblies of the RATs could be understrength and fracture when the RAT is rotating. The E:\FR\FM\16MRR1.SGM 16MRR1

Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-02-06 for 
certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. 
AD 2015-02-06 required a revision to the airplane flight manual, a 
revision to the maintenance or inspection program, as applicable, and 
replacement of horizontal stabilizer trim actuators (HSTAs) having 
certain part numbers. This new AD continues to require those actions 
and corrects certain typographical errors. This AD was prompted by the 
discovery of three typographical errors in AD 2015-02-06. We are 
issuing this AD to detect and correct loose spur gear bolts on the 
HSTA, which, if combined with the failure of the primary load path, 
could lead to failure of the HSTA and subsequent loss of the airplane.

DATES: This AD becomes effective March 16, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 6, 2015

SUPPLEMENTARY INFORMATION:

Discussion

    On January 11, 2015, we issued AD 2015-02-06, Amendment 39-18073 
(80 FR 5017, January 30, 2015). AD 2015-02-06 applied to certain 
Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. AD 2015-
02-06 was prompted by reports of loose, broken, or backed-out spur gear 
bolts on the HSTA. AD 2015-02-06 required a revision to the airplane 
flight manual, a revision to the maintenance or inspection program, as 
applicable, and replacement of HSTAs having certain part numbers. We 
issued AD 2015-02-06 to detect and correct loose spur gear bolts on the 
HSTA, which, if combined with the failure of the primary load path, 
could lead to failure of the HSTA and subsequent loss of the airplane.
    Since we issued AD 2015-02-06, Amendment 39-18073 (80 FR 5017, 
January 30, 2015), three typographical errors were discovered in AD 
2015-02-06.
    As published, a digit was missing from the engineer's phone number 
in the FOR FURTHER INFORMATION CONTACT section of the preamble of AD 
2015-02-06, Amendment 39-18073 (80 FR 5017, January 30, 2015). The 
correct phone number is ``516-228-7331.''
    As published, the AD number of AD 2015-02-06, Amendment 39-18073 
(80 FR 5017, January 30, 2015), appears as ``2014-02-06'' in the 
Product Identification line of the regulatory text of the AD. The 
correct AD number is ``2015-02-06.'' The AD number is referenced 
correctly throughout the remainder of that document.
    As published, a vendor part number in paragraph (j) of AD 2015-02-
06, Amendment 39-18073 (80 FR 5017, January 30, 2015), was incorrectly 
identified as ``845401.'' The correct vendor part number is ``8454-1.''
    Since this new AD replaces AD 2015-02-06, Amendment 39-18073 (80 FR 
5017, January 30, 2015), there are no additional changes in this new 
AD.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of 
the urgency to correct the part number and AD number errors to avoid 
non-compliance. Therefore, we determined that notice and opportunity 
for public comment before issuing this AD are impracticable and that 
good cause exists for making this amendment effective in fewer than 30 
days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2015-0491; Directorate 
Identifier 2015-NM-019-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 125 airplanes of U.S. registry.
    The actions required by AD 2015-02-06, Amendment 39-18073 (80 FR 
5017, January 30, 2015), and retained in this AD take about 21 work-
hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost about $0 per product. Based on these figures, the 
estimated cost of the actions that are required by AD 2015-02-06 is 
$1,785 per product.
    The new requirements of this AD add no additional economic burden.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
