SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) 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 
SNPRM published in the Federal Register on June 30, 2017 (82 FR 29786) 
(``the SNPRM''). We preceded the SNPRM with a notice of proposed 
rulemaking (NPRM) that published in the Federal Register on January 11, 
2017 (82 FR 3217) (``the NPRM''). The NPRM proposed to require a one-
time inspection of certain fuel line clamps for discrepancies, and 
replacement of any discrepant clamps. The NPRM was prompted by reports 
of broken bonding wires of certain fuel line clamps. The SNPRM proposed 
to expand the applicability and require repetitive inspections of 
certain fuel line clamps for discrepancies; repetitive inspections of 
certain jet fuel pumps, connection parts, and fuel lines for chafing 
marks; a measurement of the depth of the chafing marks on affected 
parts; and replacement of any discrepant parts. We are issuing this AD 
to prevent the loss of bonding function, which, in

[[Page 52841]]

combination with a lightning strike, could create a source of ignition 
in a fuel tank, possibly resulting in a fire or explosion and 
consequent loss of the airplane.
    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 for certain 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 of 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the SNPRM and 
the FAA's response to that comment.

Request To Incorporate a New Optional Terminating Action

    One commenter, Christoph Thallmayr, stated that 328 Support 
Services has released Service Bulletin SB-328-28-553, Revision 1, dated 
July 10, 2017; and Service Bulletin SB-328J-28-322, Revision 1, dated 
July 10, 2017. The commenter noted that this service information 
contains instructions for a modification, which is considered a 
terminating action to the inspections specified in the SNPRM. The 
commenter requested that we incorporate the terminating action and 
applicable service information into the final rule.
    We agree with the commenter's request. We have added paragraph (l) 
to this AD to allow operators to accomplish an optional terminating 
modification, which must be done in accordance with 328 Support 
Services GmbH Service Bulletin SB-328-28-553, Revision 1, dated July 
10, 2017; or Service Bulletin SB-328J-28-322, Revision 1, dated July 
10, 2017; as applicable. We also have redesignated subsequent 
paragraphs accordingly.

Conclusion

    We reviewed the relevant data, considered the comment 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 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.
    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

    328 Support Services GmbH 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 discrepant parts. These 
documents are distinct since they apply to different airplane models.
    328 Support Services GmbH has also issued Service Bulletin SB-328-
28-553, Revision 1, dated July 10, 2017; and Service Bulletin SB-328J-
28-322, Revision 1, dated July 10, 2017. The service information 
describes procedures for modifying the wing tank distribution system. 
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.

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 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
