SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (SNPRM) to
amend 14 CFR part 39 to supersede AD
2006–06–09, Amendment 39–14518 (71
FR 14365, March 22, 2006) (‘‘AD 2006–
06–06’’); AD 2012–05–08, Amendment
39–16980 (77 FR 16155, March 20,
2012) (‘‘AD 2012–05–08’’); and AD
2012–07–08, Amendment 39–17014 (77
FR 24342, April 24, 2012) (‘‘AD 2012–
07–08’’); which applied to all Embraer
S.A. Model ERJ 170 airplanes.
The SNPRM published in the Federal
Register on September 12, 2016 (81 FR
62668) (‘‘the SNPRM’’). We preceded
the SNPRM with a notice of proposed
rulemaking (NPRM) that published in
the Federal Register on February 27,
2014 (79 FR 11013) (‘‘the NPRM’’). The
NPRM was prompted by a
determination that more restrictive
maintenance requirements and
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
airworthiness limitations are necessary
than those required by AD 2012–07–08.
The NPRM proposed to require a
revision to the maintenance or
inspection program, as applicable, to
incorporate new inspections. The
SNPRM also proposed to revise the
maintenance or inspection program, as
applicable, to incorporate the new
airworthiness limitations section of the
maintenance review board report
(MRBR), remove certain airplanes from
the applicability, and supersede AD
2006–06–09, AD 2012–05–08, and AD
2012–07–08, which require tasks that
are now included in the new revision of
the MRBR.
We are issuing this AD to detect and
correct fatigue cracking of various PSEs;
such cracking could result in reduced
structural integrity of the airplane. We
are also issuing this AD to prevent
safety-significant latent failures; such
failures, in combination with one or
more other specified failures or events,
could result in a hazardous or
catastrophic failure condition of
avionics, hydraulic systems, fire
detection systems, fuel systems, or other
critical systems. We are also issuing this
AD to prevent the potential for ignition
sources inside fuel tanks caused by
latent failures, alterations, repairs, or
maintenance actions; such failures, in
combination with flammable fuel
vapors, could result in fuel tank
explosions and consequent loss of the
airplane.
ˆ
The Agencia Nacional de Aviacao
¸˜
Civil (ANAC), which is the aviation
authority for Brazil, has issued Brazilian
Airworthiness Directive 2015–06–01,
effective June 2, 2015 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
on certain Embraer S.A. Model ERJ 170
airplanes. The MCAI states:
This [Brazilian] AD was prompted by a
new revision to the airworthiness limitations
of the Maintenance Review Board Report.
This [Brazilian] AD is being issued to ensure
that fatigue cracking of various principal
structural elements is detected and corrected;
such fatigue cracking, could adversely affect
the structural integrity of these airplanes.
The required action is revising the
maintenance or inspection program, as
applicable, to incorporate the
airworthiness limitations in Appendix
A—Airworthiness Limitations to the

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 Allow Use of Future
Revisions of Service Information
SkyWest Airlines requested an
allowance for future revisions of the
EMBRAER 170/175 Maintenance
Review Board Report, MRB–1621,
(‘‘MRB–1621’’), to be used as long as the
tasks, intervals, and requirements
haven’t changed. The commenter stated
that if the purpose of the SNPRM was
to ensure that operators are using the
new airworthiness limitations, it would
seem that using later revisions of MRB–
1621, as long as the tasks, intervals, and
requirements haven’t changed would
make it easier to comply with the
proposed requirements, and with the
airworthiness limitation revisions that
come with newly delivered airplanes.
The commenter explained that operators
might have to divide their maintenance
and inspection program into groups of
airplanes. For airplanes with the serial
numbers identified in the SNPRM,
operators would be required to use
MRB–1621, Revision 10, and for newly
delivered airplanes operators would be
required to comply with the EMBRAER
170/175 Maintenance Review Board
Report revision released when the new
airplanes were delivered.
We agree with the commenter’s
observation that operators might have to
use two different revisions of MRB–
1621, the revision required by this final
rule and the revision that is released
with newly delivered airplanes;
however, in an AD we may not refer to
any document that does not yet exist.
Allowing the use of a ‘‘later revision’’ of
a specific service document violates
Office of the Federal Register (OFR)
regulations for approval of materials
‘‘incorporated by reference,’’ as
specified in 1 CFR 51.1(f).
Operators may request approval to use
later revisions of a referenced document
as an alternative method of compliance
(AMOC) under the provisions specified
in paragraph (k)(1) of this AD. The FAA
routinely approves AMOCs that allow
operators to incorporate later revisions
of referenced ALI documents (issued
after publication of the AD) into their
maintenance or inspection programs
instead of the revision required by an
AD. This allows an operator to comply
with both the AD, for affected airplanes,
and the airplane’s type design for later
delivered airplanes. We have not
changed this AD regarding this issue.
Conclusion
We reviewed the available data,
including the comment received, and
determined that air safety and the
public interest require adopting this AD
as proposed, with minor editorial
changes. We have determined that these
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.

limitations are necessary. We are issuing this
AD to detect and correct fatigue cracking of
various principal structural elements (PSEs);
such cracking could result in reduced
structural integrity of the airplane. We are
also issuing this AD to prevent safetysignificant latent failures; such failures, in
combination with one or more other
specified failures or events, could result in a
hazardous or catastrophic failure condition of
avionics, hydraulic systems, fire detection
systems, fuel systems, or other critical

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 to supersede AD 2006-06-09, Amendment 39-14518 (71
FR 14365, March 22, 2006) (``AD 2006-06-06''); AD 2012-05-08, Amendment
39-16980 (77 FR 16155, March 20, 2012) (``AD 2012-05-08''); and AD
2012-07-08, Amendment 39-17014 (77 FR 24342, April 24, 2012) (``AD
2012-07-08''); which applied to all Embraer S.A. Model ERJ 170
airplanes.
The SNPRM published in the Federal Register on September 12, 2016
(81 FR 62668) (``the SNPRM''). We preceded the SNPRM with a notice of
proposed rulemaking (NPRM) that published in the Federal Register on
February 27, 2014 (79 FR 11013) (``the NPRM''). The NPRM was prompted
by a determination that more restrictive maintenance requirements and
airworthiness limitations are necessary than those required by AD 2012-
07-08. The NPRM proposed to require a revision to the maintenance or
inspection program, as applicable, to incorporate new inspections. The
SNPRM also proposed to revise the maintenance or inspection program, as
applicable, to incorporate the new airworthiness limitations section of
the maintenance review board report (MRBR), remove certain airplanes
from the applicability, and supersede AD 2006-06-09, AD 2012-05-08, and
AD 2012-07-08, which require tasks that are now included in the new
revision of the MRBR.
We are issuing this AD to detect and correct fatigue cracking of
various PSEs; such cracking could result in reduced structural
integrity of the airplane. We are also issuing this AD to prevent
safety-significant latent failures; such failures, in combination with
one or more other specified failures or events, could result in a
hazardous or catastrophic failure condition of avionics, hydraulic
systems, fire detection systems, fuel systems, or other critical
systems. We are also issuing this AD to prevent the potential for
ignition sources inside fuel tanks caused by latent failures,
alterations, repairs, or maintenance actions; such failures, in
combination with flammable fuel vapors, could result in fuel tank
explosions and consequent loss of the airplane.
The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC),
which is the aviation authority for Brazil, has issued Brazilian
Airworthiness Directive 2015-06-01, effective June 2, 2015 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition on certain Embraer S.A.
Model ERJ 170 airplanes. The MCAI states:
This [Brazilian] AD was prompted by a new revision to the
airworthiness limitations of the Maintenance Review Board Report.
This [Brazilian] AD is being issued to ensure that fatigue cracking
of various principal structural elements is detected and corrected;
such fatigue cracking, could adversely affect the structural
integrity of these airplanes.
The required action is revising the maintenance or inspection
program, as applicable, to incorporate the airworthiness limitations in
Appendix A--Airworthiness Limitations to the EMBRAER 170/175
Maintenance
[[Page 16726]]
Review Board Report, MRB-1621, Revision 10, dated February 23, 2015,
which is divided into four parts: Part 1--Certification Maintenance
Requirements (CMR), Part 2--Airworthiness Limitation Inspections
(ALI)--Structures, Part 3--Fuel System Limitation Items (FSL), and Part
4--Life Limited Items (LLI).
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-2014-
0059.
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 Allow Use of Future Revisions of Service Information
SkyWest Airlines requested an allowance for future revisions of the
EMBRAER 170/175 Maintenance Review Board Report, MRB-1621, (``MRB-
1621''), to be used as long as the tasks, intervals, and requirements
haven't changed. The commenter stated that if the purpose of the SNPRM
was to ensure that operators are using the new airworthiness
limitations, it would seem that using later revisions of MRB-1621, as
long as the tasks, intervals, and requirements haven't changed would
make it easier to comply with the proposed requirements, and with the
airworthiness limitation revisions that come with newly delivered
airplanes. The commenter explained that operators might have to divide
their maintenance and inspection program into groups of airplanes. For
airplanes with the serial numbers identified in the SNPRM, operators
would be required to use MRB-1621, Revision 10, and for newly delivered
airplanes operators would be required to comply with the EMBRAER 170/
175 Maintenance Review Board Report revision released when the new
airplanes were delivered.
We agree with the commenter's observation that operators might have
to use two different revisions of MRB-1621, the revision required by
this final rule and the revision that is released with newly delivered
airplanes; however, in an AD we may not refer to any document that does
not yet exist. Allowing the use of a ``later revision'' of a specific
service document violates Office of the Federal Register (OFR)
regulations for approval of materials ``incorporated by reference,'' as
specified in 1 CFR 51.1(f).
Operators may request approval to use later revisions of a
referenced document as an alternative method of compliance (AMOC) under
the provisions specified in paragraph (k)(1) of this AD. The FAA
routinely approves AMOCs that allow operators to incorporate later
revisions of referenced ALI documents (issued after publication of the
AD) into their maintenance or inspection programs instead of the
revision required by an AD. This allows an operator to comply with both
the AD, for affected airplanes, and the airplane's type design for
later delivered airplanes. We have not changed this AD regarding this
issue.
Conclusion
We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting
this AD as proposed, with minor editorial changes. We have determined
that these 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.
Related Service Information Under 1 CFR Part 51
Embraer S.A. has issued Appendix A--Airworthiness Limitations to
the EMBRAER 170/175 Maintenance Review Board Report, MRB-1621, Revision
10, dated February 23, 2015, which is divided into four parts. As noted
in the titles of each of these parts, Appendix A addresses
Certification Maintenance Requirements (CMRs), airworthiness limitation
inspections (ALIs) for structures, fuel system limitation items (FSLs),
and life-limited items (LLI), and includes established tasks and
intervals.
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.
Costs of Compliance
We estimate that this AD affects 286 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on
Action Labor cost Parts Cost per U.S.
cost product operators
----------------------------------------------------------------------------------------------------------------
Revision of the maintenance or inspection 1 work-hour x $85 per hour = $85 $0 $85 $24,310
program (retained action from AD 2012-07-08).
Revision of the maintenance or inspection 1 work-hour x $85 per hour = $85 0 85 24,310
program (new action).
----------------------------------------------------------------------------------------------------------------
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
[[Page 16727]]
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.

controls; 28, Fuel; 52, Doors; 53, Fuselage; 54, Nacelles/pylons;
55, Stabilizers; 57, Wings; 71, Powerplant; and 78, Exhaust.
(e) Reason
This AD was prompted by a determination that more restrictive
airworthiness limitations are necessary. We are issuing this AD to
detect and correct fatigue cracking of various principal structural
elements (PSEs); such cracking could result in reduced structural
integrity of the airplane. We are also issuing this AD to prevent
safety-significant latent failures; such failures, in combination
with one or more other specified failures or events, could result in
a hazardous or catastrophic failure condition of avionics, hydraulic
systems, fire detection systems, fuel systems, or other critical
systems. We are also issuing this AD to prevent the potential for
ignition sources inside fuel tanks caused by latent failures,
alterations, repairs, or maintenance actions; such failures, in
combination with flammable fuel vapors, could result in fuel tank
explosions and consequent loss of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Maintenance Program Revision, With No Changes
This paragraph restates the action required by paragraph (i) of
AD 2012-07-08, with no changes.
(1) Within 60 days after May 29, 2012 (the effective date of AD
2012-07-08): Revise the maintenance program to incorporate the new
or revised tasks specified in Part 2--Airworthiness Limitation
Inspection (ALI)--Structures, of Appendix A, Airworthiness
Limitations, to the EMBRAER 170 Maintenance Review Board Report
(MRBR), MRB-1621, Revision 7, dated November 11, 2010; and EMBRAER
Temporary Revision 7-1, dated February 11, 2011, to Part 2--
Airworthiness Limitation Inspection (ALI)--Structures, of Appendix
A, Airworthiness Limitations, to the EMBRAER 170 MRBR, MRB-1621,
Revision 7, dated November 11, 2010; with the initial compliance
times and intervals specified in these documents.
(2) The initial compliance times for the tasks start from the
date of issuance of the original Brazilian airworthiness certificate
or the date of issuance of the original Brazilian export certificate
of airworthiness of the applicable airplane at the applicable time
specified in the tasks, or within 600 flight cycles after revising
the maintenance program, whichever occurs later. For certain tasks,
the compliance times depend on the pre-modification and post-
modification status of the actions specified in the associated
service bulletin, as specified in the ``Applicability'' column of
Part 2--Airworthiness Limitation Inspection (ALI)--Structures, of
Appendix A, Airworthiness Limitations, to the EMBRAER 170 MRBR, MRB-
1621, Revision 7, dated November 11, 2010; and EMBRAER Temporary
Revision 7-1, dated February 11, 2011, to Part 2--Airworthiness
Limitation Inspection (ALI)--Structures, of Appendix A,
Airworthiness Limitations, to the EMBRAER 170 MRBR, MRB-1621,
Revision 7, dated November 11, 2010.
(h) Retained No Alternative Actions Intervals, and/or Critical Design
Configuration Control Limitations (CDCCLs), With New Exception
This paragraph restates the action required by paragraph (j) of
AD 2012-07-08, with a new exception. Except as required by paragraph
(i) of this AD, after accomplishing the revisions required by
paragraph (g) of this AD, no alternative actions (e.g.,
inspections), intervals, and/or CDCCLs may be used other than those
specified in Part 2--Airworthiness Limitation Inspection (ALI)--
Structures, of Appendix A, Airworthiness Limitations, of the EMBRAER
170 MRBR MRB-1621, Revision 7, dated November 11, 2010; and EMBRAER
Temporary Revision 7-1, dated February 11, 2011, to Part 2--
Airworthiness Limitation Inspection (ALI)--Structures, of Appendix
A, Airworthiness Limitations, of the EMBRAER 170 MRBR, MRB-1621,
Revision 7, dated November 11, 2010; unless the actions, intervals,
and/or CDCCLs are approved as an alternative method of compliance
(AMOC) in accordance with the procedures specified in paragraph
(k)(1) of this AD.
(i) New Revision of Maintenance or Inspection Program
Within 12 months after the effective date of this AD, revise the
maintenance or inspection program, as applicable, to incorporate the
airworthiness limitations specified in Part 1--Certification
Maintenance Requirements (CMR); Part 2--Airworthiness Limitation
Inspections (ALI)--Structures; Part 3--Fuel System Limitation Items
(FSL); and Part 4--Life Limited Items (LLI); of Appendix A--
Airworthiness Limitations; of the EMBRAER 170/175 MRBR, MRB-1621,
Revision 10, dated February 23, 2015. The initial compliance times
and repetitive intervals are specified in the applicable part of the
EMBRAER 170/175 MRBR, MRB-1621, Revision 10, dated February 23,
2015. Accomplishing the revision to the maintenance or inspection
program required by this paragraph terminates the requirements of
paragraph (g) of this AD.
(j) No Alternative Actions, Intervals, or CDCCLs
After accomplishing the revision required by paragraph (i) of
this AD, no alternative actions (e.g., inspections), intervals, or
CDCCLs may be used unless the actions, intervals, and CDCCLs are
approved as an AMOC in accordance with the procedures specified in
paragraph (k)(1) of this AD.
