The NPRM published in the Federal Register on January 11, 2017 (82 FR 3217). The NPRM was prompted by reports of broken bonding wires of certain fuel line clamps. The NPRM proposed to require a one-time inspection of certain fuel line clamps for discrepancies, and replacement of any discrepant clamps. Actions Since the NPRM Was Issued Since we issued the NPRM, we have determined that repetitive inspections are necessary to address the unsafe condition and that additional airplanes are affected by the unsafe condition and must be added to the applicability. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017–0016, dated January 31, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on all 328 Support Services GmbH Model 328–100 and Model 328–300 airplanes. The MCAI states: Occurrences of broken bonding wires of the fuel line clamps have been reported on VerDate Sep<11>2014 15:56 Jun 29, 2017 Jkt 241001 Dornier 328–100 and Dornier 328–300 aeroplanes equipped with fuel line clamps Part Number (P/N) 14C02–10A, or P/N 14C02–12A, or P/N 14C02–16A. The affected fuel line clamps have been installed in accordance with the instructions of Dornier 328 Service Bulletin (SB) SB–328–28–490 or SB–328J–28–241, as applicable, to reduce occurrences of fuel line chafing. The results of the investigation did not identify design deficiency or production failure of the fuel line clamps. It is assumed that the chafing and breaking of the bonding wires are caused either by excessive vibration, misalignment, excessive installation tolerances or mistakes on installation or a combination thereof. This condition, if not detected and corrected, could lead to the loss of bonding function and, in combination with a lightning strike, create a source of ignition in a fuel tank, possibly resulting in a fire or explosion and consequent loss of the aeroplane. To address the unsafe condition, 328 Support Services issued Alert SB (ASB) ASB–328–28–041 (for Dornier 328–100) and ASB–328J–28–018 (for Dornier 328–300), providing inspection instructions. Consequently, EASA issued AD 2016–0169 [which corresponds to the NPRM] to require a one-time inspection of the fuel line clamps and, depending on findings, replacement. That [EASA] AD also required the reporting off all inspection results to the design approval holder. Since that [EASA] AD was issued, it was determined that repetitive inspections are necessary and 328 Support Services revised the applicable ASBs accordingly. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2016–0169, which is superseded, and requires repetitive inspections of all Hydraflow fuel line clamps [i.e., a general visual inspection of all Hydraflow fuel line clamps for worn and missing bonding wires; a general visual inspection of the jet pump outlet, connection part, and fuel lines for chafing marks; and a measurement of the depth of the chafing marks on affected parts] and continued reporting to the TC Holder. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 9568. Related Service Information Under 1 CFR Part 51 328 Support Services has issued Alert Service Bulletin ASB–328J–28–018, Revision 2, dated December 12, 2016; and Alert Service Bulletin ASB–328– 28–041, Revision 2, dated December 12, 2016. The service information describes procedures for a general visual inspection of all Hydraflow fuel line clamps for worn and missing bonding wires; a general visual inspection of the jet pump outlet, connection part, and fuel lines for chafing marks; a measurement of the depth of the chafing PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 29787 marks, and replacement of affected parts. These documents are distinct since they apply to different airplane models. 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. Comments We gave the public the opportunity to participate in developing this proposed AD. We considered the comments received. Request To Refer to Updated Service Information Two commenters, Patrick Brady and Christoph Thallmayr, requested that we revise the proposed AD to refer to the latest 328 Support Services Service Bulletins. The commenters stated that updated versions of the service information specify repetitive inspections at intervals of 2,500 flight hours. The commenters further noted that EASA issued an updated AD, which references the latest service information. Patrick Brady noted that the repetitive inspections could be scheduled with recurring ‘‘5A’’ inspections to ensure no additional downtime is needed. We agree with the request. We have revised this AD to refer to the updated service information and MCAI. FAA’s Determination and Requirements of This SNPRM 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Costs of Compliance We estimate that this SNPRM affects 25 airplanes of U.S. registry We estimate the following costs to comply with this proposed AD: E:\FR\FM\30JNP1.SGM 30JNP1 29788 Federal Register / Vol. 82, No. 125 / Friday, June 30, 2017 / Proposed Rules ESTIMATED COSTS Action Labor cost Inspections .............................. 8 work-hours × $85 per hour = $680 per inspection cycle.. 1 work-hour × $85 per hour = $85 per inspection cycle.

The control number for the collection of information required by this proposed AD is 2120– 0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory.

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 VerDate Sep<11>2014 15:56 Jun 29, 2017 Jkt 241001 Cost per product Up to $673. because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. § 39.13 Regulatory Findings 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH): Docket No. FAA–2016–9568; Directorate Identifier 2016–NM–150–AD. We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 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.

rulemaking (NPRM) by expanding the applicability and making certain 
inspections repetitive. We are proposing this AD to address the unsafe 
condition on these products. Since these actions impose an additional 
burden over those proposed in the NPRM, we are reopening the comment 
period to allow the public the chance to comment on these proposed 
changes.

DATES: The comment period for the NPRM published in the Federal 
Register on January 11, 2017 (82 FR 3217), is reopened.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain 328 Support Services GmbH Model 328-100 and 
Model 328-300 airplanes. The NPRM published in the Federal Register on 
January 11, 2017 (82 FR 3217). The NPRM was prompted by reports of 
broken bonding wires of certain fuel line clamps. The NPRM proposed to 
require a one-time inspection of certain fuel line clamps for 
discrepancies, and replacement of any discrepant clamps.

Actions Since the NPRM Was Issued

    Since we issued the NPRM, we have determined that repetitive 
inspections are necessary to address the unsafe condition and that 
additional airplanes are affected by the unsafe condition and must be 
added to the applicability.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0016, dated January 31, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all 328 Support 
Services GmbH Model 328-100 and Model 328-300 airplanes. The MCAI 
states:

    Occurrences of broken bonding wires of the fuel line clamps have 
been reported on Dornier 328-100 and Dornier 328-300 aeroplanes 
equipped with fuel line clamps Part Number (P/N) 14C02-10A, or P/N 
14C02-12A, or P/N 14C02-16A. The affected fuel line clamps have been 
installed in accordance with the instructions of Dornier 328 Service 
Bulletin (SB) SB-328-28-490 or SB-328J-28-241, as applicable, to 
reduce occurrences of fuel line chafing.
    The results of the investigation did not identify design 
deficiency or production failure of the fuel line clamps. It is 
assumed that the chafing and breaking of the bonding wires are 
caused either by excessive vibration, misalignment, excessive 
installation tolerances or mistakes on installation or a combination 
thereof.
    This condition, if not detected and corrected, could lead to the 
loss of bonding function and, in combination with a lightning 
strike, create a source of ignition in a fuel tank, possibly 
resulting in a fire or explosion and consequent loss of the 
aeroplane.
    To address the unsafe condition, 328 Support Services issued 
Alert SB (ASB) ASB-328-28-041 (for Dornier 328-100) and ASB-328J-28-
018 (for Dornier 328-300), providing inspection instructions.
    Consequently, EASA issued AD 2016-0169 [which corresponds to the 
NPRM] to require a one-time inspection of the fuel line clamps and, 
depending on findings, replacement. That [EASA] AD also required the 
reporting off all inspection results to the design approval holder.
    Since that [EASA] AD was issued, it was determined that 
repetitive inspections are necessary and 328 Support Services 
revised the applicable ASBs accordingly.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0169, which is superseded, and requires 
repetitive inspections of all Hydraflow fuel line clamps [i.e., a 
general visual inspection of all Hydraflow fuel line clamps for worn 
and missing bonding wires; a general visual inspection of the jet 
pump outlet, connection part, and fuel lines for chafing marks; and 
a measurement of the depth of the chafing marks on affected parts] 
and continued reporting to the TC Holder.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9568.

Related Service Information Under 1 CFR Part 51

    328 Support Services has issued Alert Service Bulletin ASB-328J-28-
018, Revision 2, dated December 12, 2016; and Alert Service Bulletin 
ASB-328-28-041, Revision 2, dated December 12, 2016. The service 
information describes procedures for a general visual inspection of all 
Hydraflow fuel line clamps for worn and missing bonding wires; a 
general visual inspection of the jet pump outlet, connection part, and 
fuel lines for chafing marks; a measurement of the depth of the chafing 
marks, and replacement of affected parts. These documents are distinct 
since they apply to different airplane models. 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.

Comments

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

Request To Refer to Updated Service Information

    Two commenters, Patrick Brady and Christoph Thallmayr, requested 
that we revise the proposed AD to refer to the latest 328 Support 
Services Service Bulletins. The commenters stated that updated versions 
of the service information specify repetitive inspections at intervals 
of 2,500 flight hours. The commenters further noted that EASA issued an 
updated AD, which references the latest service information. Patrick 
Brady noted that the repetitive inspections could be scheduled with 
recurring ``5A'' inspections to ensure no additional downtime is 
needed.
    We agree with the request. We have revised this AD to refer to the 
updated service information and MCAI.

FAA's Determination and Requirements of This SNPRM

    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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.
    Certain changes described above expand the scope of the NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Costs of Compliance

    We estimate that this SNPRM affects 25 airplanes of U.S. registry
    We estimate the following costs to comply with this proposed AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this AD has been 
detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this AD is mandatory. Comments concerning the accuracy 
of this burden and suggestions for reducing the burden should be 
directed to the FAA at 800 Independence Ave SW., Washington, DC 20591, 
ATTN: Information Collection Clearance Officer, AES-200.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
