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
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.

AD docket on the Internet at https://
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:

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

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. 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.

AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all
Airbus Model A310 series airplanes.
This proposed AD was prompted by a
revision of certain airworthiness
limitation items (ALI) documents,
which require more restrictive
maintenance requirements and
airworthiness limitations. This
proposed AD would require revising the
maintenance or inspection program to
incorporate the maintenance
requirements and airworthiness
limitations. We are proposing this AD to
address the unsafe condition on these
products.
SUMMARY:
We must receive comments on
this proposed AD by August 14, 2017.

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 https://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:
[[Page 29788]]

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.
