Download as PDF Federal Register / Vol. 78, No. 250 / Monday, December 30, 2013 / Rules and Regulations exemption or relieves a restriction; (2) interpretive rules and statements of policy; or (3) as otherwise provided by the agency for good cause found and published with the rule. 5 U.S.C. 553(d). At a minimum, the Bureau believes the amendments fall under the third exception to section 553(d). The Bureau finds that there is good cause to make the amendments effective on January 1, 2014. The amendment in this notice is technical and non-discretionary, and it applies the method previously established in the agency’s regulations for automatic adjustments to the threshold. Regulatory Flexibility Act Because no notice of proposed rulemaking is required, the Regulatory Flexibility Act does not require an initial or final regulatory flexibility analysis. 5 U.S.C. 603(a), 604(a). iii. As of the end of the preceding calendar year, the creditor had total assets that are less than the asset threshold for the relevant calendar year. For calendar year 2014, the asset threshold is $2,028,000,000. Creditors that had total assets of less than $2,028,000,000 on December 31, 2013, satisfy this criterion for purposes of the exemption during 2014. This asset threshold shall adjust automatically each year based on the year-toyear change in the average of the Consumer Price Index for Urban Wage Earners and Clerical Workers, not seasonally adjusted, for each 12-month period ending in November, with rounding to the nearest million dollars. The Bureau will publish notice of the asset threshold each year by amending this comment. For historical purposes, the prior asset threshold was: A. For calendar year 2013, the asset threshold was $2,000,000,000. Creditors that had total assets of less than $2,000,000,000 on December 31, 2012, satisfied this criterion for purposes of the exemption during 2013. * * * * * Dated: December 24, 2013.

This AD was prompted by a report that traces of oil could be found in the crew oxygen system due to the use of incorrect pressure testing procedures during manufacturing. This AD requires cleaning the crew oxygen system. We are issuing this AD to detect and correct oil contaminants, which could cause an ignition and result in a fire in the oxygen system.

SUPPLEMENTARY INFORMATION: Discussion 14 CFR Part 39 PART 1026—TRUTH IN LENDING (REGULATION Z) 79287 Sfmt 4700 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. The NPRM published in the Federal Register on May 10, 2013 (78 FR 27314). The NPRM proposed to correct an unsafe condition for the specified products. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–01, dated January 22, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: It was found that traces of oil could be present in the crew oxygen system due to the use of incorrect pressure testing procedures during manufacturing. Field sampling of nine aeroplanes have confirmed this condition. When the oxygen system is used, oil contaminants can cause an ignition and result in a fire in the oxygen system. This [Canadian] AD mandates the cleaning of the crew oxygen system to reduce oil contaminants to a safe level. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/ E:\FR\FM\30DER1.SGM 30DER1 79288 Federal Register / Vol. 78, No. 250 / Monday, December 30, 2013 / Rules and Regulations #!documentDetail;D=FAA-2013-03700002. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request to Revise the NPRM (78 FR 27314, May 10, 2013) Based On New Service Information ExpressJet requested the NPRM (78 FR 27314, May 10, 2013) be revised due to a new revision of the service information. ExpressJet stated that since the NPRM was issued, Bombardier Service Bulletin 670BA–35–012, Revision B, including Appendix A, dated May 6, 2013, has been released. We agree with ExpressJet’s request to use Bombardier Service Bulletin 670BA–35–012, Revision B, including Appendix A, dated May 6, 2013. We have updated paragraph (g) of this final rule in this regard. We have also added a new paragraph (h) to this final rule to give credit for actions done before the effective date of this AD using Bombardier Service Bulletin 670BA–35– 012, dated August 3, 2012; and Bombardier Service Bulletin 670BA–35– 012, Revision A, dated November 26, 2012. Subsequent paragraphs have been redesignated accordingly. addition, TCCA and Bombardier, Inc., reviewed the risks and found the compliance time to be adequate. We have not changed the final rule in this regard. Request To Revise the Compliance Time We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 27314, May 10, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 27314, May 10, 2013). The Air Line Pilots Association (ALPA) requested we revise the compliance time. ALPA stated it understands the requirements of the NPRM (78 FR 27314, May 10, 2013) take 51 work-hours per product, but stated that the safety benefit would necessitate a compliance time of between 12 and 24 months. We do not agree with ALPA’s request. We determined that the proposed compliance time of ‘‘within 6,600 flight hours or 36 months after the effective date of this AD, whichever occurs first’’ is appropriate in consideration of the safety implications, the average utilization rate of the affected fleet, and the practical aspects of an orderly cleaning of the crew oxygen system. In Conclusion Costs of Compliance We estimate that this AD affects 400 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Cleaning the Crew Oxygen System ............... 51 work-hours × $85 per hour = $4,335 ........ $827 $5,162 $2,064,800 Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. wreier-aviles on DSK5TPTVN1PROD with RULES 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. VerDate Mar<15>2010 15:10 Dec 27, 2013 Jkt 232001 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.

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. 
The NPRM published in the Federal Register on May 10, 2013 (78 FR 
27314). The NPRM proposed to correct an unsafe condition for the 
specified products.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-01, dated January 22, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    It was found that traces of oil could be present in the crew 
oxygen system due to the use of incorrect pressure testing 
procedures during manufacturing. Field sampling of nine aeroplanes 
have confirmed this condition. When the oxygen system is used, oil 
contaminants can cause an ignition and result in a fire in the 
oxygen system.
    This [Canadian] AD mandates the cleaning of the crew oxygen 
system to reduce oil contaminants to a safe level.

    You may examine the MCAI in the AD docket on the Internet at http:/

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request to Revise the NPRM (78 FR 27314, May 10, 2013) Based On New 
Service Information

    ExpressJet requested the NPRM (78 FR 27314, May 10, 2013) be 
revised due to a new revision of the service information. ExpressJet 
stated that since the NPRM was issued, Bombardier Service Bulletin 
670BA-35-012, Revision B, including Appendix A, dated May 6, 2013, has 
been released.
    We agree with ExpressJet's request to use Bombardier Service 
Bulletin 670BA-35-012, Revision B, including Appendix A, dated May 6, 
2013. We have updated paragraph (g) of this final rule in this regard. 
We have also added a new paragraph (h) to this final rule to give 
credit for actions done before the effective date of this AD using 
Bombardier Service Bulletin 670BA-35-012, dated August 3, 2012; and 
Bombardier Service Bulletin 670BA-35-012, Revision A, dated November 
26, 2012. Subsequent paragraphs have been redesignated accordingly.

Request To Revise the Compliance Time

    The Air Line Pilots Association (ALPA) requested we revise the 
compliance time. ALPA stated it understands the requirements of the 
NPRM (78 FR 27314, May 10, 2013) take 51 work-hours per product, but 
stated that the safety benefit would necessitate a compliance time of 
between 12 and 24 months.
    We do not agree with ALPA's request. We determined that the 
proposed compliance time of ``within 6,600 flight hours or 36 months 
after the effective date of this AD, whichever occurs first'' is 
appropriate in consideration of the safety implications, the average 
utilization rate of the affected fleet, and the practical aspects of an 
orderly cleaning of the crew oxygen system. In addition, TCCA and 
Bombardier, Inc., reviewed the risks and found the compliance time to 
be adequate. We have not changed the final rule in this regard.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 27314, May 10, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 27314, May 10, 2013).

Costs of Compliance

    We estimate that this AD affects 400 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    Where the service information lists required parts costs that are 
covered under warranty, we have assumed that there will be no charge 
for these costs. As we do not control warranty coverage for affected 
parties, some parties may incur costs higher than estimated here.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
