Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC–8–400 series airplanes. This AD was prompted by reports of chafing of the fuel lines due to contact with the surrounding structures in the fuel tank. This AD requires replacing and modifying fuel lines, revising the maintenance or inspection program, as applicable, to include critical design configuration control limitations (CDCCL) and airworthiness limitation (AWL) items, and, for certain airplanes, removing certain clamps and mounting hardware. We are issuing this AD to prevent chafing of the fuel lines in the fuel tank, which could result in potential ignition sources in the fuel tank in the event of a lightning strike and consequent fire or explosion. DATES: This AD becomes effective October 7, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 7, 2015.

SUPPLEMENTARY INFORMATION: asabaliauskas on DSK5VPTVN1PROD with RULES 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 DHC–8–400 series airplanes. The NPRM published in the Federal Register on August 26, 2014 (79 FR 50860). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–09R1, dated May 28, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model DHC–8–400 series airplanes. The MCAI states: Reports from operators have revealed a number of instances of chafing of the fuel lines due to contact with the surrounding structures in the fuel tank. An internal audit conducted by Bombardier revealed a number of locations in the fuel tank where low clearances were noted between fuel lines and the surrounding structure. Low clearances between fuel lines and the surrounding structures may result in ignition sources in the fuel tank in the event of a lightning strike, creating an unacceptable level of safety. Bombardier had issued Service Bulletin (SB) 84–28–09 to introduce new fuel line assemblies that include new fuel lines and Teflon protective sleeves, and SBs 84–28–10 and 84–28–13 to remove unnecessary hardware in the wing fuel tanks, in order to eliminate potential fouling conditions on the affected fuel lines. Upon an operator’s incorporation of SB 84– 28–09, an additional fouling condition was identified on the post-modification fuel lines. In order to address this concern on the aeroplane, Bombardier has issued SBs 84– 28–14 and 84–28–15, along with ModSum IS4Q2800012 to rectify this problem. This [Canadian] AD mandates the replacement of fuel lines and the installation of fuel line Teflon protective sleeves. In addition, the fuel line Teflon protective sleeves have been added to the Critical Design Configuration Control Limitations (CDCCL) along with the introduction of associated Fuel System Limitations tasks, to ensure integrity of the new assembly. Since the original issue of this [Canadian] AD, it was found that there were editorial VerDate Sep<11>2014 19:00 Sep 01, 2015 Jkt 235001 errors in Parts IB and II A of this [Canadian] AD. In addition, the Temporary Revisions (TR) Airworthiness Limitation Items (ALI)– 111/–112 ‘‘referenced’’ in Parts III and IV of this AD had been superseded by later revisions. This [Canadian] AD is revised to correct the editorial errors and accept the later TR approved by Transport Canada. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-05830002. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 50860, August 26, 2014) and the FAA’s response to each comment. Request To Refer to Revised Service Information All Nippon Airways (ANA) and Horizon Air requested that we revise paragraph (g) of the proposed AD (79 FR 50860, August 26, 2014) to refer to the following service information: • Bombardier Service Bulletin 84–28– 14, Revision A, dated June 9, 2014 • Bombardier Service Bulletin 84–28– 09, Revision D, January 29, 2013 • Bombardier Service Bulletin 84–28– 15, dated August 17, 2012 Horizon also requested that we revise paragraph (n) of the proposed AD (79 FR 50860, August 26, 2014) to provide credit for the prior accomplishment of the actions specified in Bombardier Service Bulletin 84–28–14, dated August 17, 2012. We agree with the requests and have revised paragraphs (g)(1), (g)(2)(i), (g)(2)(ii), and (m) of this AD accordingly. We have also redesignated paragraph (n) of the proposed AD (79 FR 50860, August 26, 2014) as paragraph (n)(1) of this AD, and added new paragraph (n)(2) to this AD to indicate the new credit service information. Request To Clarify Certain Affected Airplanes ANA requested that we correct the identity of the affected airplanes in paragraph (g)(2) of the proposed AD (79 FR 50860, August 26, 2014). Although paragraph (g)(2) of the NPRM specified airplanes on which ModSum 4–113643 ‘‘was incorporated’’ in production, ANA noted that this requirement should apply to airplanes on which ModSum 4–113643 ‘‘was not incorporated’’ in production. ANA noted that ModSum 4–113643 is equivalent to the Bombardier Service Bulletin 84–28–09. We agree with the request. The intent of the NPRM (79 FR 50860, August 26, PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 2014) was to include only airplanes on which neither the ModSum nor the corresponding service bulletin was done. We have revised paragraph (g)(2) of this AD accordingly. Request To Exclude Specific Access and Close Requirements Horizon Air requested that we revise paragraphs (g) and (i) of the proposed AD (79 FR 50860, August 26, 2014) to exclude the Job Set-up and the Close Out sections in certain service information, because these actions do not directly correct the unsafe condition. Horizon Air stated that requiring the actions in these sections restricts an operator’s ability to do other maintenance actions concurrently with the actions required by this AD. We agree to revise paragraphs (g) and (i) of this AD to specify only the actions in paragraph B., ‘‘Procedures,’’ which correct the unsafe condition. Request To Allow Use of Later Revisions of Service Information ANA requested that we allow use of ‘‘later revisions’’ of the service information, as done in the MCAI. We disagree with the request. We cannot use the phrase ‘‘or later revisions’’ in an AD when referring to service documents because doing so violates Office of the Federal Register (OFR) regulations for approval of materials ‘‘incorporated by reference’’ in rules. See 1 CFR 51.1(f). In general terms, we are required by these OFR regulations to either publish the service document contents as part of the actual AD language; or submit the service document to the OFR for approval as ‘‘referenced’’ material, in which case we may refer to such material in the text of an AD. The AD may refer to service documents only if the OFR has approved them for incorporation by reference. See 1 CFR part 51. To allow operators to use later revisions of the referenced document (issued after publication of the AD), either we must revise the AD to refer to specific later revisions, or operators must request approval to use later revisions as an alternative method of compliance with this AD under the provisions of paragraph (o)(1) of this AD. We have not changed this AD regarding this issue. Conclusion We reviewed the relevant data, considered 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 minor changes: E:\FR\FM\02SER1.SGM 02SER1 Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations asabaliauskas on DSK5VPTVN1PROD with RULES • Are consistent with the intent that was proposed in the NPRM (79 FR 50860, August 26, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 50860, August 26, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. 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 of this NPRM. Costs of Compliance We estimate that this AD affects 72 airplanes of U.S. registry. We also estimate that it will take about 80 workhours per product to comply with the basic requirements of this AD. The Related Service Information Under 1 average labor rate is $85 per work-hour. CFR Part 51 Required parts will cost about $2,845 Bombardier has issued the following per product.

This rule revises the authority paragraphs for the affected parts to cite the most recent such notice, which the President signed on August 7, 2015. This rule is purely procedural, and makes no changes other than to revise CFR authority paragraphs for the purpose of making the authority citations current. It does not change the text of any section of the EAR, nor does it alter any right, obligation or prohibition that applies to any person under the EAR. Rulemaking Requirements 1.

This rule does not impose any regulatory burden on the public and is consistent with the goals of Executive Order 13563. This rule has been determined to be not significant for purposes of Executive Order 12866. 2. Notwithstanding any other provision of law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

This rule does not contain policies with Federalism implications as that term is defined under Executive Order 13132. 4. The Department finds that there is good cause under 5 U.S.C. 553(b)(B) to waive the provisions of the Administrative Procedure Act requiring prior notice and the opportunity for public comment because they are unnecessary. This rule only updates legal authority citations. It clarifies information and is non-discretionary. This rule does not alter any right, obligation or prohibition that applies to any person under the EAR. Because these revisions are not substantive changes, it is unnecessary to provide notice and opportunity for public comment. In addition, the 30-day delay in effectiveness otherwise required by 5 U.S.C. 553(d) is not applicable because this rule is not a substantive rule. Because neither the Administrative Procedure Act nor any other law requires that notice of proposed rulemaking and an opportunity for public comment be given for this rule, the analytical requirements of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) are not applicable.

Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted 
by reports of chafing of the fuel lines due to contact with the 
surrounding structures in the fuel tank. This AD requires replacing and 
modifying fuel lines, revising the maintenance or inspection program, 
as applicable, to include critical design configuration control 
limitations (CDCCL) and airworthiness limitation (AWL) items, and, for 
certain airplanes, removing certain clamps and mounting hardware. We 
are issuing this AD to prevent chafing of the fuel lines in the fuel 
tank, which could result in potential ignition sources in the fuel tank 
in the event of a lightning strike and consequent fire or explosion.

DATES: This AD becomes effective October 7, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 7, 
2015.

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 DHC-8-400 series airplanes. The NPRM published in the Federal 
Register on August 26, 2014 (79 FR 50860).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-09R1, dated May 28, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model DHC-8-400 series 
airplanes. The MCAI states:

    Reports from operators have revealed a number of instances of 
chafing of the fuel lines due to contact with the surrounding 
structures in the fuel tank. An internal audit conducted by 
Bombardier revealed a number of locations in the fuel tank where low 
clearances were noted between fuel lines and the surrounding 
structure. Low clearances between fuel lines and the surrounding 
structures may result in ignition sources in the fuel tank in the 
event of a lightning strike, creating an unacceptable level of 
safety.
    Bombardier had issued Service Bulletin (SB) 84-28-09 to 
introduce new fuel line assemblies that include new fuel lines and 
Teflon protective sleeves, and SBs 84-28-10 and 84-28-13 to remove 
unnecessary hardware in the wing fuel tanks, in order to eliminate 
potential fouling conditions on the affected fuel lines.
    Upon an operator's incorporation of SB 84-28-09, an additional 
fouling condition was identified on the post-modification fuel 
lines. In order to address this concern on the aeroplane, Bombardier 
has issued SBs 84-28-14 and 84-28-15, along with ModSum IS4Q2800012 
to rectify this problem.
    This [Canadian] AD mandates the replacement of fuel lines and 
the installation of fuel line Teflon protective sleeves. In 
addition, the fuel line Teflon protective sleeves have been added to 
the Critical Design Configuration Control Limitations (CDCCL) along 
with the introduction of associated Fuel System Limitations tasks, 
to ensure integrity of the new assembly.
    Since the original issue of this [Canadian] AD, it was found 
that there were editorial errors in Parts IB and II A of this 
[Canadian] AD. In addition, the Temporary Revisions (TR) 
Airworthiness Limitation Items (ALI)-111/-112 ``referenced'' in 
Parts III and IV of this AD had been superseded by later revisions. 
This [Canadian] AD is revised to correct the editorial errors and 
accept the later TR approved by Transport Canada.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0583-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 50860, August 26, 2014) and the FAA's response to each comment.

Request To Refer to Revised Service Information

    All Nippon Airways (ANA) and Horizon Air requested that we revise 
paragraph (g) of the proposed AD (79 FR 50860, August 26, 2014) to 
refer to the following service information:

 Bombardier Service Bulletin 84-28-14, Revision A, dated June 
9, 2014
 Bombardier Service Bulletin 84-28-09, Revision D, January 29, 
2013
 Bombardier Service Bulletin 84-28-15, dated August 17, 2012

    Horizon also requested that we revise paragraph (n) of the proposed 
AD (79 FR 50860, August 26, 2014) to provide credit for the prior 
accomplishment of the actions specified in Bombardier Service Bulletin 
84-28-14, dated August 17, 2012.
    We agree with the requests and have revised paragraphs (g)(1), 
(g)(2)(i), (g)(2)(ii), and (m) of this AD accordingly. We have also 
redesignated paragraph (n) of the proposed AD (79 FR 50860, August 26, 
2014) as paragraph (n)(1) of this AD, and added new paragraph (n)(2) to 
this AD to indicate the new credit service information.

Request To Clarify Certain Affected Airplanes

    ANA requested that we correct the identity of the affected 
airplanes in paragraph (g)(2) of the proposed AD (79 FR 50860, August 
26, 2014). Although paragraph (g)(2) of the NPRM specified airplanes on 
which ModSum 4-113643 ``was incorporated'' in production, ANA noted 
that this requirement should apply to airplanes on which ModSum 4-
113643 ``was not incorporated'' in production. ANA noted that ModSum 4-
113643 is equivalent to the Bombardier Service Bulletin 84-28-09.
    We agree with the request. The intent of the NPRM (79 FR 50860, 
August 26, 2014) was to include only airplanes on which neither the 
ModSum nor the corresponding service bulletin was done. We have revised 
paragraph (g)(2) of this AD accordingly.

Request To Exclude Specific Access and Close Requirements

    Horizon Air requested that we revise paragraphs (g) and (i) of the 
proposed AD (79 FR 50860, August 26, 2014) to exclude the Job Set-up 
and the Close Out sections in certain service information, because 
these actions do not directly correct the unsafe condition. Horizon Air 
stated that requiring the actions in these sections restricts an 
operator's ability to do other maintenance actions concurrently with 
the actions required by this AD.
    We agree to revise paragraphs (g) and (i) of this AD to specify 
only the actions in paragraph B., ``Procedures,'' which correct the 
unsafe condition.

Request To Allow Use of Later Revisions of Service Information

    ANA requested that we allow use of ``later revisions'' of the 
service information, as done in the MCAI.
    We disagree with the request. We cannot use the phrase ``or later 
revisions'' in an AD when referring to service documents because doing 
so violates Office of the Federal Register (OFR) regulations for 
approval of materials ``incorporated by reference'' in rules. See 1 CFR 
51.1(f). In general terms, we are required by these OFR regulations to 
either publish the service document contents as part of the actual AD 
language; or submit the service document to the OFR for approval as 
``referenced'' material, in which case we may refer to such material in 
the text of an AD. The AD may refer to service documents only if the 
OFR has approved them for incorporation by reference. See 1 CFR part 
51.
    To allow operators to use later revisions of the referenced 
document (issued after publication of the AD), either we must revise 
the AD to refer to specific later revisions, or operators must request 
approval to use later revisions as an alternative method of compliance 
with this AD under the provisions of paragraph (o)(1) of this AD. We 
have not changed this AD regarding this issue.

Conclusion

    We reviewed the relevant data, considered 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 minor changes:

[[Page 52957]]

     Are consistent with the intent that was proposed in the 
NPRM (79 FR 50860, August 26, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 50860, August 26, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
     Service Bulletin 84-28-09, Revision D, dated January 29, 
2013, which describes procedures for replacing fuel lines, adding 
Teflon tubing to certain fuel lines in the fuel tank, and contacting 
the manufacturer for certain corrective actions.
     Service Bulletin 84-28-10, Revision B, dated March 19, 
2013, which describes procedures for inspecting for the presence of 
certain clamps and hardware and, if those are present, removing those 
certain clamps and mounting hardware.
     Service Bulletin 84-28-13, dated August 17, 2012, which 
describes procedures for removing certain clamps and mounting hardware.
     Service Bulletin 84-28-14, Revision A, dated June 9, 2014, 
which describes procedures for replacing a tube assembly.
     Service Bulletin 84-28-15, dated August 17, 2012, which 
describes procedures for replacing fuel lines, adding Teflon tubing to 
certain fuel lines in the fuel tank, and contacting the manufacturer 
for certain corrective actions.
     Temporary Revision ALI-111, dated January 11, 2011, to 
Section 4-1, ``Fuel System Limitations,'' of Part 2, ``Airworthiness 
Limitation Items,'' of the Airworthiness Limitation Items section of 
Bombardier Q400 Dash 8 Maintenance Requirements Manual PSM 1-84-7, 
which describes updates to the fuel system limitations for inspections 
of the Teflon sleeve on the fuel tank vent lines.
     Temporary Revision ALI-112, dated January 11, 2011, to 
Section 5-1, ``Critical Design Configuration Control Limitations,'' of 
Part 2, ``Airworthiness Limitation Items,'' of the Airworthiness 
Limitation Items section of Bombardier Q400 Dash 8 Maintenance 
Requirements Manual PSM 1-84-7, which describes updates to the critical 
design configuration control limitations on Teflon protective sleeves 
on fuel vent lines inside the fuel tanks.
    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 of this 
NPRM.

Costs of Compliance

    We estimate that this AD affects 72 airplanes of U.S. registry. We 
also estimate that it will take about 80 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 $2,845 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $694,440, or $9,645 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 
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.
