SUPPLEMENTARY INFORMATION:
FOR FURTHER INFORMATION CONTACT:
Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2022–0097,
dated June 1, 2022 (EASA AD 2022–
0097), to correct an unsafe condition on
Airbus Helicopters Deutschland GmbH
Model EC135 P1, EC135 P2, EC135 P2+,
EC135 P3, EC135 T1, EC135 T2, EC135
T2+, EC135 T3, EC635 P2+, EC635 P3,
EC635 T1, EC635 T2+, EC635 T3, MBB–
BK117 C–2, MBB–BK117 D–2, MBB–
BK117 D–3, and MBB–BK117 D–3m
helicopters.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus Helicopters
Deutschland GmbH (AHD) Model
EC135P1, EC135P2, EC135P2+,
EC135P3, EC135T1, EC135T2,
EC135T2+, EC135T3, MBB–BK 117 C–2,
MBB–BK 117 D–2, and MBB–BK 117 D–
3 helicopters. The NPRM published in
the Federal Register on November 13,
2023 (88 FR 77536). The NPRM was
prompted by the determination that IFR
screens obstruct the pilot’s views. These
IFR screens may be used for IFR
training. According to Airbus
Helicopters, the IFR screens obstruct the
pilot’s view to the front and to the right.
The NPRM proposed to require
removing certain part-numbered IFR
screens, as specified in EASA AD 2022–
0097.
The FAA is issuing this AD to address
the obstructed views, which could lead
to reduced situational awareness of the
pilot and subsequent mid-air collision.
See EASA AD 2022–0097 for additional
background information.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
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
PO 00000
Frm 00029
Fmt 4700
Sfmt 4700
18777
described in its AD. The FAA reviewed
the relevant data and determined that
air safety requires adopting this AD as
proposed. Accordingly, the FAA is
issuing this AD to address the unsafe
condition on these helicopters. This AD
is adopted as proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
EASA AD 2022–0097 requires
removing certain part-numbered IFR
screens and prohibits installing them on
any helicopter.
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 also reviewed Airbus
Helicopters Alert Service Bulletin (ASB)
EC135–25A–033, ASB EC135H–25A–
007, ASB MBB–BK117 C–2–25A–022,
and ASB MBB–BK117 D–2–25A–023,
each Revision 0 and dated May 23,
2022, which specify procedures for
removing the lower, pilot door, and
upper IFR screens from the helicopter.
This service information also specifies
that the lower, pilot door, and upper IFR
screens must not be installed on a
helicopter and the respective
maintenance manual task is invalid and
must no longer be used.
Differences Between This AD and the
EASA AD
EASA AD 2022–0097 applies to
Model EC635 P2+, EC635 P3, EC635 T1,
EC635 T2+, EC635 T3, and MBB–BK117
D–3m helicopters, whereas this AD does
not because those model helicopters are
not FAA type-certificated and are not
included on the U.S. type certificate
data sheet except where the U.S. type
certificate data sheet explains that the
Model EC635T2+ helicopter having
serial number 0858 was converted from
Model EC635T2+ to Model EC135T2+.
Costs of Compliance
The FAA estimates that this AD
affects 573 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 AD.
Removing the IFR screens takes
approximately 0.5 work-hour for an
estimated cost of $43 per helicopter and
up to $24,639 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
E:\FR\FM\15MRR1.SGM
15MRR1
18778
Federal Register / Vol. 89, No. 52 / Friday, March 15, 2024 / Rules and Regulations
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.
(a) Effective Date
This airworthiness directive (AD) is
effective April 19, 2024.
Regulatory Findings
(d) Subject
Joint Aircraft Service Component (JASC)
Code: 2500, Cabin Equipment/Furnishings.
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) Will not affect intrastate aviation
in Alaska, and
(3) 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:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0097, dated June 1, 2022 (EASA
AD 2022-0097), to correct an unsafe condition on Airbus Helicopters
Deutschland GmbH Model EC135 P1, EC135 P2, EC135 P2+, EC135 P3, EC135
T1, EC135 T2, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635
T2+, EC635 T3, MBB-BK117 C-2, MBB-BK117 D-2, MBB-BK117 D-3, and MBB-
BK117 D-3m helicopters.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus Helicopters
Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3,
EC135T1, EC135T2, EC135T2+, EC135T3, MBB-BK 117 C-2, MBB-BK 117 D-2,
and MBB-BK 117 D-3 helicopters. The NPRM published in the Federal
Register on November 13, 2023 (88 FR 77536). The NPRM was prompted by
the determination that IFR screens obstruct the pilot's views. These
IFR screens may be used for IFR training. According to Airbus
Helicopters, the IFR screens obstruct the pilot's view to the front and
to the right. The NPRM proposed to require removing certain part-
numbered IFR screens, as specified in EASA AD 2022-0097.
The FAA is issuing this AD to address the obstructed views, which
could lead to reduced situational awareness of the pilot and subsequent
mid-air collision. See EASA AD 2022-0097 for additional background
information.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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 reviewed the relevant
data and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these helicopters. This AD is adopted as proposed in the
NPRM.
Related Service Information Under 1 CFR Part 51
EASA AD 2022-0097 requires removing certain part-numbered IFR
screens and prohibits installing them on any helicopter.
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 also reviewed Airbus Helicopters Alert Service Bulletin
(ASB) EC135-25A-033, ASB EC135H-25A-007, ASB MBB-BK117 C-2-25A-022, and
ASB MBB-BK117 D-2-25A-023, each Revision 0 and dated May 23, 2022,
which specify procedures for removing the lower, pilot door, and upper
IFR screens from the helicopter. This service information also
specifies that the lower, pilot door, and upper IFR screens must not be
installed on a helicopter and the respective maintenance manual task is
invalid and must no longer be used.
Differences Between This AD and the EASA AD
EASA AD 2022-0097 applies to Model EC635 P2+, EC635 P3, EC635 T1,
EC635 T2+, EC635 T3, and MBB-BK117 D-3m helicopters, whereas this AD
does not because those model helicopters are not FAA type-certificated
and are not included on the U.S. type certificate data sheet except
where the U.S. type certificate data sheet explains that the Model
EC635T2+ helicopter having serial number 0858 was converted from Model
EC635T2+ to Model EC135T2+.
Costs of Compliance
The FAA estimates that this AD affects 573 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 AD.
Removing the IFR screens takes approximately 0.5 work-hour for an
estimated cost of $43 per helicopter and up to $24,639 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
[[Page 18778]]
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
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) Will not affect intrastate aviation in Alaska, and
(3) 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.
