This proposed AD would require
revising the airworthiness limitations
section (ALS) of the existing helicopter
maintenance manual or instructions for
continued airworthiness for your
helicopter and the existing approved
maintenance or inspection program for
your helicopter, as applicable, to reduce
the inspection interval of certain parts,
as specified in a European Union
Aviation Safety Agency (EASA) AD,
which is proposed for incorporation by
reference (IBR). The FAA is proposing
this AD to address the unsafe condition
on these products.

Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2021–0290,
dated and corrected December 23, 2021
(EASA AD 2021–0290), to correct an
unsafe condition for all serial-numbered

Model MBB–BK117 D–3 and D–3m
helicopters.
This proposed AD was prompted by
recalculations of the inspection
intervals for certain parts. The FAA is
proposing this AD to reduce the
inspection intervals for certain parts.
See EASA AD 2021–0290 for additional
background information.
Related Service Information Under 1
CFR Part 51
EASA AD 2021–0290 requires
replacing components before exceeding
their life limits and accomplishing
maintenance tasks within thresholds
and intervals specified in the applicable
ALS. Depending on the results of the
maintenance tasks, EASA AD 2021–
0290 requires accomplishing corrective
action(s) or contacting AHD [Airbus
Helicopters Deutschland GmbH] for
approved instructions and
accomplishing those instructions. EASA
AD 2021–0290 also requires revising the
Aircraft Maintenance Programme (AMP)
by incorporating the limitations, tasks,
and associated thresholds and intervals
described in the specified ALS as
applicable to helicopter model and
configuration. Revising the AMP
constitutes terminating action for the
requirements to replace components
before exceeding their life limits and
accomplish maintenance tasks within
thresholds and intervals specified in the
applicable ALS as required by EASA AD
2021–0290.
This material 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.

FAA’s Determination
These helicopters have been approved
by EASA and are approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with the
European Union, EASA has notified the
FAA about the unsafe condition
described in its AD. The FAA is
proposing this AD after evaluating all
known relevant information and
determining that the unsafe condition
described previously is likely to exist or
develop on other helicopters of the same
type design.
ddrumheller on DSK120RN23PROD with PROPOSALS1
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
EASA AD 2021–0290, described
previously, as incorporated by
reference, except for any differences
identified as exceptions in the
regulatory text of this proposed AD and
except as discussed under ‘‘Differences
Between this Proposed AD and the
EASA AD.’’
Explanation of Required Compliance
Information
In the FAA’s ongoing efforts to
improve the efficiency of the AD
process, the FAA developed a process to
use some civil aviation authority (CAA)
ADs as the primary source of
information for compliance with
requirements for corresponding FAA
ADs. The FAA has been coordinating
this process with manufacturers and
CAAs. As a result, the FAA proposes to
incorporate EASA AD 2021–0290 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2021–0290
through that incorporation, except for
any differences identified as exceptions
in the regulatory text of this proposed
AD. Using common terms that are the
same as the heading of a particular
section in EASA AD 2021–0290 does
not mean that operators need comply
only with that section. For example,
where the AD requirement refers to ‘‘all
required actions and compliance times,’’
compliance with this AD requirement is
not limited to the section titled
‘‘Required Action(s) and Compliance
Time(s)’’ in EASA AD 2021–0290.
Service information referenced in EASA
AD 2021–0290 for compliance will be
available at regulations.gov under
Docket No. FAA–2023–1816 after the
FAA final rule is published.
Differences Between This Proposed AD
and the EASA AD
EASA AD 2021–0290 applies to
Model MBB–BK117 D–3m helicopters,
whereas this proposed AD would not
VerDate Sep<11>2014
16:52 Sep 06, 2023
Jkt 259001
because that model is not FAA typecertificated.
EASA AD 2021–0290 requires
replacing certain components before
exceeding applicable life limits,
accomplishing certain maintenance
tasks within thresholds and intervals as
specified in the ALS, as defined within,
and depending on the results,
accomplishing corrective action within
the compliance time specified in that
ALS. EASA AD 2021–0290 also requires
revising the approved AMP to
incorporate the limitations, tasks, and
associated thresholds and intervals
described in that ALS within 12 months
after its effective date. Whereas, this
proposed AD would require revising
existing documents and programs
within 30 days to incorporate the
limitations, tasks, and associated
thresholds and intervals described in
that ALS, and clarifies that if an
incorporated limitation or threshold
therein is reached before 30 days after
the effective date of the final rule of this
proposed AD, you still have up to 30
days after the effective date of the final
rule of this proposed AD to accomplish
the corresponding task.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 29
helicopters of U.S. Registry. Labor rates
are estimated at $85 per work-hour.
Based on these numbers, the FAA
estimates the following costs to comply
with this proposed AD.
Revising the ALS of the existing
helicopter maintenance manual or
instructions for continued airworthiness
for your helicopter and the existing
approved maintenance or inspection
program for your helicopter, as
applicable, would take about 2 workhours for an estimated cost of $170 per
helicopter and $4,930 for the U.S. fleet.
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.
The FAA is 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
PO 00000
Frm 00008
Fmt 4702
Sfmt 4702
61487
that authority because it addresses an
unsafe condition that is likely to exist or
develop on products identified in this
rulemaking action.
Regulatory Findings
The FAA 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) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0290, dated and corrected
December 23, 2021 (EASA AD 2021-0290), to correct an unsafe condition
for all serial-numbered Airbus Helicopters Deutschland GmbH Model MBB-
BK117 D-3 and D-3m helicopters.
This proposed AD was prompted by recalculations of the inspection
intervals for certain parts. The FAA is proposing this AD to reduce the
inspection intervals for certain parts. See EASA AD 2021-0290 for
additional background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0290 requires replacing components before exceeding
their life limits and accomplishing maintenance tasks within thresholds
and intervals specified in the applicable ALS. Depending on the results
of the maintenance tasks, EASA AD 2021-0290 requires accomplishing
corrective action(s) or contacting AHD [Airbus Helicopters Deutschland
GmbH] for approved instructions and accomplishing those instructions.
EASA AD 2021-0290 also requires revising the Aircraft Maintenance
Programme (AMP) by incorporating the limitations, tasks, and associated
thresholds and intervals described in the specified ALS as applicable
to helicopter model and configuration. Revising the AMP constitutes
terminating action for the requirements to replace components before
exceeding their life limits and accomplish maintenance tasks within
thresholds and intervals specified in the applicable ALS as required by
EASA AD 2021-0290.
This material 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.
Other Related Service Information
The FAA reviewed Airbus Helicopters Alert Service Bulletin ASB MBB-
BK117 D-3-04A-001, Revision 0, dated December 22, 2021. This service
information specifies checking the total accumulated flight hours since
new for bolt part number (P/N) D671M7501201, bolt P/N D671M7501211, and
mast bolt P/N D620M0501203, and accomplishing the airworthiness
inspection within the reduced airworthiness inspection interval of 400
flight hours.
The FAA also reviewed Airbus MBB-BK117 D-3 Chapter 04, ALS,
Revision 1, dated December 14, 2021. This service information specifies
airworthiness limitations, tasks, and associated thresholds and
intervals for various parts. Revision 1 of this service information
specifies various updates for certain components.
[[Page 61487]]
FAA's Determination
These helicopters have been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA about the
unsafe condition described in its AD. The FAA is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2021-0290, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed AD and except as discussed under
``Differences Between this Proposed AD and the EASA AD.''
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2021-0290 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2021-0290 through that incorporation, except for any
differences identified as exceptions in the regulatory text of this
proposed AD. Using common terms that are the same as the heading of a
particular section in EASA AD 2021-0290 does not mean that operators
need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2021-
0290. Service information referenced in EASA AD 2021-0290 for
compliance will be available at regulations.gov under Docket No. FAA-
2023-1816 after the FAA final rule is published.
Differences Between This Proposed AD and the EASA AD
EASA AD 2021-0290 applies to Model MBB-BK117 D-3m helicopters,
whereas this proposed AD would not because that model is not FAA type-
certificated.
EASA AD 2021-0290 requires replacing certain components before
exceeding applicable life limits, accomplishing certain maintenance
tasks within thresholds and intervals as specified in the ALS, as
defined within, and depending on the results, accomplishing corrective
action within the compliance time specified in that ALS. EASA AD 2021-
0290 also requires revising the approved AMP to incorporate the
limitations, tasks, and associated thresholds and intervals described
in that ALS within 12 months after its effective date. Whereas, this
proposed AD would require revising existing documents and programs
within 30 days to incorporate the limitations, tasks, and associated
thresholds and intervals described in that ALS, and clarifies that if
an incorporated limitation or threshold therein is reached before 30
days after the effective date of the final rule of this proposed AD,
you still have up to 30 days after the effective date of the final rule
of this proposed AD to accomplish the corresponding task.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 29 helicopters of U.S. Registry. Labor rates are estimated at
$85 per work-hour. Based on these numbers, the FAA estimates the
following costs to comply with this proposed AD.
Revising the ALS of the existing helicopter maintenance manual or
instructions for continued airworthiness for your helicopter and the
existing approved maintenance or inspection program for your
helicopter, as applicable, would take about 2 work-hours for an
estimated cost of $170 per helicopter and $4,930 for the U.S. fleet.
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.
The FAA is 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
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
