Model CL–600–2A12 (CL–601 Variant), and CL–600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. This AD was prompted by a report that a potential chafing condition exists between the negative-G fuel feed drain line of the auxiliary power unit (APU) and its surrounding structure and components. This AD requires, for certain airplanes, a detailed inspection for chafing conditions of the negative-G fuel feed drain line of the APU, and corrective actions if necessary. For certain other airplanes, this AD requires replacement of the APU negative-G fuel feed tube assembly and the drain line. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is January 9, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of January 9, 2017.

Model CL–600–2A12 (CL–601 Variant), and CL–600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. The NPRM published in the Federal Register on June 28, 2016 (81 FR 41889) (‘‘the NPRM’’). The NPRM was prompted by a report that a potential chafing condition exists between the negative-G fuel feed drain line of the APU and its surrounding structure and components. The NPRM proposed to require, for certain airplanes, a detailed inspection for chafing conditions of the negative-G fuel feed drain line of the APU, and corrective actions if necessary. For certain other airplanes, the NPRM proposed to require replacement of the APU negative-G fuel feed tube assembly and the drain line. We are issuing this AD to prevent a chafing condition in the negative-G fuel PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 feed drain line, which can result in fuel leaking from the drain line. This condition, in combination with a nearby hot surface or other potential ignition source, could result in an uncontrolled fire in the aft equipment bay. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2015–26, dated August 31, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model CL–600–2A12 (CL–601 Variant) and CL–600–2B16 (CL–601–3A, CL– 601–3R, and CL–604 Variants) airplanes. The MCAI states: It was reported that a potential chaffing condition exist between the Auxiliary Power Unit (APU) negative-G fuel feed drain line and its surrounding structure and components. Leakage of the negative-G fuel feed drain line is a dormant failure, however, in combination with a nearby hot surface or other potential ignition source, could result in an uncontrolled fire in the aft equipment bay. This [Canadian] AD mandates [for certain airplanes] the detailed visual inspection [for chafing conditions, e.g., fouling between the drain line and other components and insufficient clearance] and, if required, rectification [corrective actions], to ensure required clearance between the APU negative-G fuel feed drain line and its surrounding structure and components [and, for certain other airplanes, this [Canadian] AD mandates replacement of the APU negative-G fuel feed tube assembly and the drain line].

These service bulletins are distinct since they apply to different airplane models. • Bombardier Service Bulletin 605– 28–009, dated May 19, 2015. This service information describes procedures for a detailed inspection for chafing conditions of the negative-G fuel feed drain line of the APU, replacement of the APU negative-G fuel feed tube assembly and the drain line, and corrective actions. 87423 This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 504 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 Inspection and Modification ............................ 22 work-hours × $85 per hour = $1,870 ........ $6,334 $8,204 $4,134,816 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. sradovich on DSK3GMQ082PROD with RULES 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.

SUPPLEMENTARY INFORMATION: Background The Bureau of Industry and Security (BIS) issues this final rule to remove the Special Iraq Reconstruction License (SIRL) provisions from the Export Administration Regulations (EAR), consistent with the Retrospective Regulatory Review Initiative. In the preamble to the proposed rule published in the Federal Register on June 7, 2016 (81 FR 36481) (hereinafter ‘‘the June 7 proposed rule’’ or ‘‘the June 7 rule’’), BIS reviewed the origins of the SIRL, established in 2004 (69 FR 46070, July 30, 2004) to supplement options to facilitate exports and reexports to Iraq and transfers within Iraq of items in furtherance of civil reconstruction and other projects in Iraq funded by specified entities, including the United States government. BIS also reviewed the record of related transactions since the SIRL was established. The record indicates that exporters supplying items used in support of the civil reconstruction efforts in Iraq have not relied on the SIRL to advance those efforts, apparently because of its complexity and narrowness. Further, since 2004, BIS processed only three applications for the SIRL and approved only one, as compared to over 400 approved individual license applications for the export of items to Iraq between 2012 and 2015. Finally, with the implementation of updates to the EAR, the relative advantages of the SIRL have been offset by changes to individual licenses and other types of authorizations offered by BIS that provide less complex alternatives to the SIRL. Thus, consistent with the President’s Retrospective Regulatory Review Initiative to streamline regulations and reduce unnecessary regulatory burdens on the public (see ‘‘Improving Regulatory Review’’ (Executive Order 13563 of January 18, 2011)), BIS E:\FR\FM\05DER1.SGM 05DER1

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Bombardier, Inc. 
Model CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-
3R, and CL-604 Variants) airplanes. The NPRM published in the Federal 
Register on June 28, 2016 (81 FR 41889) (``the NPRM''). The NPRM was 
prompted by a report that a potential chafing condition exists between 
the negative-G fuel feed drain line of the APU and its surrounding 
structure and components. The NPRM proposed to require, for certain 
airplanes, a detailed inspection for chafing conditions of the 
negative-G fuel feed drain line of the APU, and corrective actions if 
necessary. For certain other airplanes, the NPRM proposed to require 
replacement of the APU negative-G fuel feed tube assembly and the drain 
line. We are issuing this AD to prevent a chafing condition in the 
negative-G fuel feed drain line, which can result in fuel leaking from 
the drain line. This condition, in combination with a nearby hot 
surface or other potential ignition source, could result in an 
uncontrolled fire in the aft equipment bay.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2015-26, dated August 
31, 2015 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc. Model CL-600-2A12 (CL-601 
Variant) and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. The MCAI states:

    It was reported that a potential chaffing condition exist 
between the Auxiliary Power Unit (APU) negative-G fuel feed drain 
line and its surrounding structure and components. Leakage of the 
negative-G fuel feed drain line is a dormant failure, however, in 
combination with a nearby hot surface or other potential ignition 
source, could result in an uncontrolled fire in the aft equipment 
bay.
    This [Canadian] AD mandates [for certain airplanes] the detailed 
visual inspection [for chafing conditions, e.g., fouling between the 
drain line and other components and insufficient clearance] and, if 
required, rectification [corrective actions], to ensure required 
clearance between the APU negative-G fuel feed drain line and its 
surrounding structure and components [and, for certain other 
airplanes, this [Canadian] AD mandates replacement of the APU 
negative-G fuel feed tube assembly and the drain line].

    Corrective actions include replacing the APU negative-G fuel feed 
drain line. You may examine the MCAI in the AD docket on the Internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2016-7418.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.

    This AD was prompted by a report that a potential chafing 
condition exists between the negative-G fuel feed drain line of the 
auxiliary power unit (APU) and its surrounding structure and 
components. We are issuing this AD to prevent a chafing condition in 
the negative-G fuel feed drain line, which can result in fuel 
leaking from the drain line. This condition, in combination with a 
nearby hot surface or other potential ignition source, could result 
in an uncontrolled fire in the aft equipment bay.
