Editorial, Reapproval, Revision Or
Withdrawal
The FAA expects a suitable consensus
standard to be reviewed periodically.
ASTM policy is that a consensus
standard should be reviewed in its
entirety by the responsible
subcommittee and must be balloted for
reapproval, revision, or withdrawal,
within five years of its last approval
date. ASTM reapproves a standard—
denoted by the year of reapproval in
parentheses (e.g., F2427–05a(2013))—to
indicate completion of a review cycle
with no technical changes made to the
standard. ASTM issues editorial
changes—denoted by a superscript
epsilon in the standard designation
(F3235–17 ε1)—to correct information
that does not change the meaning or
intent of a standard. Any MOC accepted
by this document that is based on a
standard later reapproved or editorially
changed is also considered accepted
without the need for a NOA. ASTM
revises a standard to make changes to its
technical content. Revisions to
consensus standards serving as the basis
for MOC accepted by this document will
not be automatically accepted and will
require further FAA acceptance in order
for the revisions to be an accepted MOC.

SUPPLEMENTARY INFORMATION:
We are superseding
Airworthiness Directive (AD) 2016–25–
18, which applied to certain
Bombardier, Inc., Model BD–700–1A10
and BD–700–1A11 airplanes. AD 2016–
25–18 required an inspection for
discrepancies of the attachment points
of the links between the engine rear
mount assemblies, and corrective
actions if necessary. This AD requires
an inspection of certain attachment
points, corrective action if necessary,
and replacement of certain bolts and
nuts in the engine rear mount
assemblies. This AD also adds airplanes
to the applicability. This AD was
prompted by the determination that
replacement of certain nuts and bolts in
the engine rear mount assemblies is
necessary. We are issuing this AD to
address the unsafe condition on these
products.
Discussion
This AD is effective June 15,
2018.
The Director of the Federal Register
approved the incorporation by reference
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016–25–18,
Amendment 39–18744 (81 FR 90961,

sradovich on DSK3GMQ082PROD with RULES
December 16, 2016) (‘‘AD 2016–25–
18’’). AD 2016–25–18 applied to certain
Bombardier, Inc., Model BD–700–1A10
and BD–700–1A11 airplanes. The
NPRM published in the Federal
Register on August 15, 2017 (82 FR
38626). The NPRM was prompted by the
determination that replacement of
certain nuts and bolts in the engine rear
mount assemblies is necessary. The
NPRM proposed to continue to require
an inspection for discrepancies of the
attachment points of the links between
the engine rear mount assemblies, and
corrective actions if necessary. The
NPRM also proposed to require an
inspection of certain attachment points,
corrective action if necessary, and
replacement of certain bolts and nuts in
the engine rear mount assemblies. The
NPRM also proposed to add airplanes to
the applicability. We are issuing this AD
to detect and correct broken engine
attachment hardware, which could
result in separation of an engine from
the airplane.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2016–23R1, dated February 20, 2017
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for certain Bombardier, Inc.,
Model BD–700–1A10 and BD–700–
1A11 airplanes. The MCAI states:
Bombardier reported that during
maintenance of a BD–700 aeroplane, the
engine mount pin, part number (P/N)
BRR15838, was found backed out of the rear
mount link. The retaining bolt, P/N AS54020,
which passes through the engine mount pin
was also found fractured at the groove which
holds the locking spring. An investigation
revealed the most probable root cause of
failure to be a single axial tension static
overload, with no evidence of fatigue
contributing to the failure.
The above condition if not detected, may
result in the loss of engine attachment to the
airframe.
As an interim corrective action,
Bombardier issued Service Bulletins (SBs)
700–71–002, 700–71–6002, 700–71–5002,
and 700–1A11–71–002 to inspect the
attachment points of the links between the
engine rear mount assemblies, and install
replacement hardware if required.
The original version of this [Canadian] AD
was issued to mandate incorporation of the
above Bombardier SBs to inspect and
maintain integrity of the affected engine rear
mount assembly.
Revision 1 of this [Canadian] AD is issued
to mandate incorporation of the Bombardier
SBs 700–71–003, 700–71–6003, 700–71–
5003, and 700–1A11–71–003 to replace the
existing bolts and self-locking nuts with new
bolts and nuts, as a final corrective action.
The MCAI also adds airplanes having
serial numbers 9764, 9766, and 9771
VerDate Sep<11>2014
22:27 May 10, 2018
Jkt 244001
through 9785 inclusive to the
applicability. Those airplanes are also
affected by the identified unsafe
condition. 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–2017–
0775.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the NPRM and the FAA’s
response to each comment.
Requests To Provide Credit for Actions
Previously Accomplished
NetJets Aviation requested that we
provide credit for accomplishing the
actions specified in paragraphs (j) and
(k) of the proposed AD prior to the
effective date of this AD. Bombardier
requested that we provide credit for
accomplishing the actions specified in
paragraphs (k) and (l) of the proposed
AD prior to the effective date of this AD.
We acknowledge the commenters’
requests and agree to clarify. Paragraph
(f) of this AD states to accomplish the
required actions within the compliance
times specified, ‘‘unless already done.’’
Therefore, if operators have
accomplished the actions required for
compliance with this AD before the
effective date of this AD, no further
action is necessary. We have not revised
this AD in this regard.
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting this AD
as proposed except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

Costs of Compliance
We estimate that this AD affects 97
airplanes of U.S. registry.
The actions required by AD 2016–25–
18, and retained in this AD take about
1 work-hour per product, at an average
labor rate of $85 per work-hour. Based
on these figures, the estimated cost of
the actions that are required by AD
2016–25–18 is $85 per product.
The retained on-condition costs in
this AD take about 2 work-hours per
product, at an average labor rate of $85
per work-hour. Required parts cost
about $730 per product. Based on these
figures, the estimated cost of the oncondition actions that are required by
AD 2016–25–18 is $900 per product.
We have received no definitive data
that would enable us to provide cost
estimates for other retained oncondition actions specified in AD 2016–
25–18.
We also estimate that it will take
about 4 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts will cost
up to $14,940 per product. Based on
these figures, we estimate the cost of
this AD on U.S. operators to be up to
$1,482,160, or up to $15,280 per
product.
We have received no definitive data
that would enable us to provide cost
estimates for the on-condition actions
specified in this AD.
According to the manufacturer, some
of the costs of this AD may be covered

sradovich on DSK3GMQ082PROD 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.
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.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016-25-18, Amendment 39-18744 (81 FR 90961,
[[Page 21856]]
December 16, 2016) (``AD 2016-25-18''). AD 2016-25-18 applied to
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
The NPRM published in the Federal Register on August 15, 2017 (82 FR
38626). The NPRM was prompted by the determination that replacement of
certain nuts and bolts in the engine rear mount assemblies is
necessary. The NPRM proposed to continue to require an inspection for
discrepancies of the attachment points of the links between the engine
rear mount assemblies, and corrective actions if necessary. The NPRM
also proposed to require an inspection of certain attachment points,
corrective action if necessary, and replacement of certain bolts and
nuts in the engine rear mount assemblies. The NPRM also proposed to add
airplanes to the applicability. We are issuing this AD to detect and
correct broken engine attachment hardware, which could result in
separation of an engine from the airplane.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2016-23R1, dated
February 20, 2017 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-
1A11 airplanes. The MCAI states:
Bombardier reported that during maintenance of a BD-700
aeroplane, the engine mount pin, part number (P/N) BRR15838, was
found backed out of the rear mount link. The retaining bolt, P/N
AS54020, which passes through the engine mount pin was also found
fractured at the groove which holds the locking spring. An
investigation revealed the most probable root cause of failure to be
a single axial tension static overload, with no evidence of fatigue
contributing to the failure.
The above condition if not detected, may result in the loss of
engine attachment to the airframe.
As an interim corrective action, Bombardier issued Service
Bulletins (SBs) 700-71-002, 700-71-6002, 700-71-5002, and 700-1A11-
71-002 to inspect the attachment points of the links between the
engine rear mount assemblies, and install replacement hardware if
required.
The original version of this [Canadian] AD was issued to mandate
incorporation of the above Bombardier SBs to inspect and maintain
integrity of the affected engine rear mount assembly.
Revision 1 of this [Canadian] AD is issued to mandate
incorporation of the Bombardier SBs 700-71-003, 700-71-6003, 700-71-
5003, and 700-1A11-71-003 to replace the existing bolts and self-
locking nuts with new bolts and nuts, as a final corrective action.
The MCAI also adds airplanes having serial numbers 9764, 9766, and
9771 through 9785 inclusive to the applicability. Those airplanes are
also affected by the identified unsafe condition. 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-2017-0775.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.
Requests To Provide Credit for Actions Previously Accomplished
NetJets Aviation requested that we provide credit for accomplishing
the actions specified in paragraphs (j) and (k) of the proposed AD
prior to the effective date of this AD. Bombardier requested that we
provide credit for accomplishing the actions specified in paragraphs
(k) and (l) of the proposed AD prior to the effective date of this AD.
We acknowledge the commenters' requests and agree to clarify.
Paragraph (f) of this AD states to accomplish the required actions
within the compliance times specified, ``unless already done.''
Therefore, if operators have accomplished the actions required for
compliance with this AD before the effective date of this AD, no
further action is necessary. We have not revised this AD in this
regard.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Costs of Compliance
We estimate that this AD affects 97 airplanes of U.S. registry.
The actions required by AD 2016-25-18, and retained in this AD take
about 1 work-hour per product, at an average labor rate of $85 per
work-hour. Based on these figures, the estimated cost of the actions
that are required by AD 2016-25-18 is $85 per product.
The retained on-condition costs in this AD take about 2 work-hours
per product, at an average labor rate of $85 per work-hour. Required
parts cost about $730 per product. Based on these figures, the
estimated cost of the on-condition actions that are required by AD
2016-25-18 is $900 per product.
We have received no definitive data that would enable us to provide
cost estimates for other retained on-condition actions specified in AD
2016-25-18.
We also estimate that it will take about 4 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost up to $14,940 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be up to $1,482,160, or up to $15,280 per product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD.
According to the manufacturer, some of the costs of this AD may be
covered
[[Page 21857]]
under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all available costs in our
cost estimate.
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.
