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 March 28, 2014 (79 FR 17459). The NPRM was prompted by fuel system reviews conducted by the manufacturer. The NPRM proposed to require replacing a fitting that is part of the refuel control solenoid valve assembly. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–32, dated October 8, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition certain Bombardier, Inc. Model DHC–8– 400 series airplanes. The MCAI states: During the incorporation of Modsum 4– 126630, mandated by [Canadian] AD CF– 2010–31 [http://wwwapps3.tc.gc.ca/Saf-SecSur/2/cawis-swimn/images/docacrobat16x16.gif; corresponding FAA AD 2011–13–06, Amendment 39–16729 (76 FR 37258, June 27, 2011)], it has been reported PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 that fitting part number (P/N) 82822074–951 has been installed through the rear spar instead of fitting P/N 82822074–005 or 82822074–007. Fitting P/N 82822074–951 does not comply with the fuel tank safety standards introduced in Chapter 525 of the Airworthiness Manual through [a certain] Notice of Proposed Amendment (NPA) * * *. Therefore, this fitting shall be replaced to mitigate unsafe conditions that could result in a potential ignition source within the fuel system. This [Canadian] AD mandates the replacement of the above-mentioned fittings with compliant fittings P/N 82822074–009. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-01460002. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM (79 FR 17459, March 28, 2014) and the FAA’s response to each comment. Request To Mandate Only Certain Sections of the Service Information Horizon Air requested that we revise the NPRM (79 FR 17459, March 28, 2014), to mandate only the section of the Accomplishment Instructions that corrects the unsafe condition (i.e., paragraph 3.B., ‘‘Procedure’’). Horizon Air reasoned that paragraph (g) of the NPRM mandates the entire Accomplishment Instructions of Bombardier Service Bulletin 84–28–12, Revision A, dated June 20, 2013, and that the ‘‘Job Set-Up’’ and ‘‘Close Out’’ sections of the Accomplishment Instructions do not directly correct the unsafe condition. Horizon Air explained that requiring the ‘‘Job Set-Up’’ and ‘‘Close Out’’ sections restricts an operator’s ability to perform other maintenance in conjunction with the incorporation of the service bulletin. As an example, Horizon Air suggested that an operator might need or want to have the gear pins out, but that would not be allowed because the NPRM mandates the installation of the gear pins through the work steps in the ‘‘Job Set-Up’’ section, and they cannot be removed until the ‘‘Job Close Out’’ section is accomplished. For the reasons stated by Horizon Air, we agree to mandate only the section of the Accomplishment Instructions of Bombardier Service Bulletin 84–28–12, E:\FR\FM\10FER1.SGM 10FER1 7286 Federal Register / Vol. 80, No. 27 / Tuesday, February 10, 2015 / Rules and Regulations rljohnson on DSK3VPTVN1PROD with RULES Revision A, dated June 20, 2013, that corrects the unsafe condition in this AD. We have revised paragraph (g) of this AD accordingly. ‘‘Contacting the Manufacturer’’ Paragraph in This AD Since late 2006, we have included a standard paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD. The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/ operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved. In the NPRM (79 FR 17459, March 28, 2014), we proposed to prevent the use of repairs that were not specifically developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to this FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase ‘‘its delegated agent’’ to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD. No comments were provided to the NPRM (79 FR 17459, March 28, 2014) about these proposed changes. However, a comment was provided for an NPRM having Directorate Identifier 2012–NM– 101 AD (78 FR 78285, December 26, 2013). The commenter stated the following: ‘‘The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.’’ This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product VerDate Sep<11>2014 15:13 Feb 09, 2015 Jkt 235001 paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19. To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it ‘‘Contacting the Manufacturer.’’ This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, the TCCA, or Bombardier, Inc.’s TCCA Design Approval Organization (DAO). The Contacting the Manufacturer paragraph also clarifies that, if approved by the DAO, the approval must include the DAO-authorized signature. The DAO Designee signature indicates that the data and information contained in the document are TCCA-approved, which is also FAA-approved. Messages and other information provided by the manufacturer that do not contain the DAO-authorized signature approval are not TCCA-approved, unless TCCA directly approves the manufacturer’s message or other information. This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers’ service instructions that are ‘‘Required for Compliance’’ with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance. Other commenters to the NPRM having Directorate Identifier 2012–NM– 101 AD (78 FR 78285, December 26, 2013) pointed out that in many cases the foreign manufacturer’s service bulletin and the foreign authority’s MCAI might PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 have been issued some time before the FAA AD. Therefore, the DOA might have provided U.S. operators with an approved repair, developed with full awareness of the unsafe condition, before the FAA AD is issued. Under these circumstances, to comply with the FAA AD, the operator would be required to go back to the manufacturer’s DOA and obtain a new approval document, adding time and expense to the compliance process with no safety benefit. Based on these comments, we removed the requirement that the DAHprovided repair specifically refer to this AD. Before adopting such a requirement, the FAA will coordinate with affected DAHs and verify they are prepared to implement means to ensure that their repair approvals consider the unsafe condition addressed in this AD. Any such requirements will be adopted through the normal AD rulemaking process, including notice-and-comment procedures, when appropriate. We also have decided not to include a generic reference to either the ‘‘delegated agent’’ or ‘‘DAH with State of Design Authority design organization approval,’’ but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH. 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: • Are consistent with the intent that was proposed in the NPRM (79 FR 17459, March 28, 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 17459, March 28, 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 Bombardier Service Bulletin 84–28–12, Revision A, dated June 20, 2013. The service information describes procedures for replacing a fitting that is part of the refuel control solenoid valve assembly. This service information is reasonably available; see ADDRESSES for ways to access this service information. E:\FR\FM\10FER1.SGM 10FER1 Federal Register / Vol. 80, No. 27 / Tuesday, February 10, 2015 / Rules and Regulations Costs of Compliance We estimate that this AD affects 55 airplanes of U.S. registry. We also estimate that it will take about 9 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts costs are negligible. Based on these figures, we estimate the cost of this AD on U.S. operators to be $42,075, or $765 per product. rljohnson on DSK3VPTVN1PROD 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. Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information.

We will consider all the comments we receive and may conduct additional rulemaking based on those comments. Discussion On October 29, 2014, we issued EAD 2014–22–51, which requires, before further flight and thereafter at intervals not to exceed 10 hours time-in-service (TIS), visually inspecting the hopper for a crack at the four attachment points. If there is a crack, EAD 2014–22–51 requires replacing the hopper with an airworthy hopper, which is not terminating action for the repetitive visual inspections. EAD 2014–22–51 was sent previously to all known U.S. owners and operators of these helicopters and resulted from several cases of a cracked MGB oil cooler hopper. EAD 2014–22–51 was prompted by EAD No. 2014–0229–E, dated October 20, 2014, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for the Airbus Helicopters Model EC130T2 helicopters. EASA advises of several cases of cracked MGB oil cooler fan attachments to the hopper. EASA EAD No. 2014– 0229–E requires repetitive visual inspections of the MGB oil cooler fan attachment to the hopper and, depending on findings, replacement of cracked parts.

Amendment 39-18094; AD 2015-02-25]
RIN 2120-AA64


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 fuel system reviews conducted by the manufacturer. This AD requires 
replacing a fitting that is part of the refuel control solenoid valve 
assembly. We are issuing this AD to prevent the potential of ignition 
sources inside fuel tanks, which, in combination with flammable fuel 
vapors, could result in fuel tank explosions and consequent loss of the 
airplane.

DATES: This AD becomes effective March 17, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 17, 
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 March 28, 2014 (79 FR 17459). The NPRM was prompted by fuel 
system reviews conducted by the manufacturer. The NPRM proposed to 
require replacing a fitting that is part of the refuel control solenoid 
valve assembly. We are issuing this AD to prevent the potential of 
ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-32, dated October 8, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition certain Bombardier, Inc. Model DHC-8-400 series 
airplanes. The MCAI states:

    During the incorporation of Modsum 4-126630, mandated by 
[Canadian] AD CF-2010-31 [http://wwwapps3.tc.gc.ca/Saf-Sec-Sur/2/cawis-swimn/images/doc-acrobat16x16.gif; corresponding FAA AD 2011-
13-06, Amendment 39-16729 (76 FR 37258, June 27, 2011)], it has been 
reported that fitting part number (P/N) 82822074-951 has been 
installed through the rear spar instead of fitting P/N 82822074-005 
or 82822074-007. Fitting P/N 82822074-951 does not comply with the 
fuel tank safety standards introduced in Chapter 525 of the 
Airworthiness Manual through [a certain] Notice of Proposed 
Amendment (NPA) * * *. Therefore, this fitting shall be replaced to 
mitigate unsafe conditions that could result in a potential ignition 
source within the fuel system.
    This [Canadian] AD mandates the replacement of the above-
mentioned fittings with compliant fittings P/N 82822074-009.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0146-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (79 FR 
17459, March 28, 2014) and the FAA's response to each comment.

Request To Mandate Only Certain Sections of the Service Information

    Horizon Air requested that we revise the NPRM (79 FR 17459, March 
28, 2014), to mandate only the section of the Accomplishment 
Instructions that corrects the unsafe condition (i.e., paragraph 3.B., 
``Procedure''). Horizon Air reasoned that paragraph (g) of the NPRM 
mandates the entire Accomplishment Instructions of Bombardier Service 
Bulletin 84-28-12, Revision A, dated June 20, 2013, and that the ``Job 
Set-Up'' and ``Close Out'' sections of the Accomplishment Instructions 
do not directly correct the unsafe condition. Horizon Air explained 
that requiring the ``Job Set-Up'' and ``Close Out'' sections restricts 
an operator's ability to perform other maintenance in conjunction with 
the incorporation of the service bulletin. As an example, Horizon Air 
suggested that an operator might need or want to have the gear pins 
out, but that would not be allowed because the NPRM mandates the 
installation of the gear pins through the work steps in the ``Job Set-
Up'' section, and they cannot be removed until the ``Job Close Out'' 
section is accomplished.
    For the reasons stated by Horizon Air, we agree to mandate only the 
section of the Accomplishment Instructions of Bombardier Service 
Bulletin 84-28-12,

[[Page 7286]]

Revision A, dated June 20, 2013, that corrects the unsafe condition in 
this AD. We have revised paragraph (g) of this AD accordingly.

``Contacting the Manufacturer'' Paragraph in This AD

    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD.
    The MCAI or referenced service information in an FAA AD often 
directs the owner/operator to contact the manufacturer for corrective 
actions, such as a repair. Briefly, the Airworthy Product paragraph 
allowed owners/operators to use corrective actions provided by the 
manufacturer if those actions were FAA-approved. In addition, the 
paragraph stated that any actions approved by the State of Design 
Authority (or its delegated agent) are considered to be FAA-approved.
    In the NPRM (79 FR 17459, March 28, 2014), we proposed to prevent 
the use of repairs that were not specifically developed to correct the 
unsafe condition, by requiring that the repair approval provided by the 
State of Design Authority or its delegated agent specifically refer to 
this FAA AD. This change was intended to clarify the method of 
compliance and to provide operators with better visibility of repairs 
that are specifically developed and approved to correct the unsafe 
condition. In addition, we proposed to change the phrase ``its 
delegated agent'' to include a design approval holder (DAH) with State 
of Design Authority design organization approval (DOA), as applicable, 
to refer to a DAH authorized to approve required repairs for the 
proposed AD.
    No comments were provided to the NPRM (79 FR 17459, March 28, 2014) 
about these proposed changes. However, a comment was provided for an 
NPRM having Directorate Identifier 2012-NM-101 AD (78 FR 78285, 
December 26, 2013). The commenter stated the following: ``The proposed 
wording, being specific to repairs, eliminates the interpretation that 
Airbus messages are acceptable for approving minor deviations 
(corrective actions) needed during accomplishment of an AD mandated 
Airbus service bulletin.''
    This comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed the paragraph and retitled 
it ``Contacting the Manufacturer.'' This paragraph now clarifies that 
for any requirement in this AD to obtain corrective actions from a 
manufacturer, the actions must be accomplished using a method approved 
by the FAA, the TCCA, or Bombardier, Inc.'s TCCA Design Approval 
Organization (DAO).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DAO, the approval must include the DAO-authorized 
signature. The DAO Designee signature indicates that the data and 
information contained in the document are TCCA-approved, which is also 
FAA-approved. Messages and other information provided by the 
manufacturer that do not contain the DAO-authorized signature approval 
are not TCCA-approved, unless TCCA directly approves the manufacturer's 
message or other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    Other commenters to the NPRM having Directorate Identifier 2012-NM-
101 AD (78 FR 78285, December 26, 2013) pointed out that in many cases 
the foreign manufacturer's service bulletin and the foreign authority's 
MCAI might have been issued some time before the FAA AD. Therefore, the 
DOA might have provided U.S. operators with an approved repair, 
developed with full awareness of the unsafe condition, before the FAA 
AD is issued. Under these circumstances, to comply with the FAA AD, the 
operator would be required to go back to the manufacturer's DOA and 
obtain a new approval document, adding time and expense to the 
compliance process with no safety benefit.
    Based on these comments, we removed the requirement that the DAH-
provided repair specifically refer to this AD. Before adopting such a 
requirement, the FAA will coordinate with affected DAHs and verify they 
are prepared to implement means to ensure that their repair approvals 
consider the unsafe condition addressed in this AD. Any such 
requirements will be adopted through the normal AD rulemaking process, 
including notice-and-comment procedures, when appropriate.
    We also have decided not to include a generic reference to either 
the ``delegated agent'' or ``DAH with State of Design Authority design 
organization approval,'' but instead we have provided the specific 
delegation approval granted by the State of Design Authority for the 
DAH.

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:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 17459, March 28, 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 17459, March 28, 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 Bombardier Service Bulletin 84-28-12, 
Revision A, dated June 20, 2013. The service information describes 
procedures for replacing a fitting that is part of the refuel control 
solenoid valve assembly. This service information is reasonably 
available; see ADDRESSES for ways to access this service information.

[[Page 7287]]

Costs of Compliance

    We estimate that this AD affects 55 airplanes of U.S. registry.
    We also estimate that it will take about 9 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts costs are negligible. Based 
on these figures, we estimate the cost of this AD on U.S. operators to 
be $42,075, or $765 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.
