Airworthiness Directives; Airbus
Helicopters
Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
Airbus Helicopters Model SA–365N,
SA–365N1, AS–365N2, AS 365 N3, EC
155B, and EC155B1 helicopters. This
proposed AD was prompted by reports
of the cockpit doors failing to open after
ditching with inflated floats on certain
helicopters equipped with an
emergency flotation system (EFS). This
proposed AD would require revising the
existing Rotorcraft Flight Manual (RFM)
for your helicopter, installing placards,
and depending on your model
helicopter, modification of the
jettisoning system, 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.
DATES: The FAA must receive comments
on this proposed AD by September 26,
2022.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:
• Federal eRulemaking Portal: Go to
www.regulations.gov. Follow the
instructions for submitting comments.

Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued a series of ADs, with
the most recent being EASA AD 2021–
0101R1, dated February 25, 2022 (EASA
AD 2021–0101R1), to correct an unsafe
condition for Airbus Helicopters (AH),

365 N, SA 365 N1, AS 365 N2, AS 365
N3, EC 155 B, and EC 155 B1
helicopters.
EASA initially issued EASA AD
2021–0041, dated January 28, 2021
(EASA AD 2021–0041), for certain
Model SA 365 N, SA 365 N1, AS 365
N2, AS 365 N3, EC 155 B, and EC 155
B1 helicopters, which required
modifying the jettisoning system by
installing an external handle on the
jettison system of the pilot and co-pilot
doors on certain Model SA/AS 365
helicopters, installing external
instruction placards on the left-hand
(LH) and right-hand (RH) side of the
helicopter, and amending the RFM.
EASA later issued EASA AD 2021–
0101, dated April 12, 2021 (EASA AD
2021–0101), which superseded EASA
AD 2021–0041, to also address Model
AS 365 helicopters with the Airbus
Helicopters Forward Looking InfraRed
(AH FLIR) system installed.
EASA AD 2021–0101R1 retains the
requirements of EASA AD 2021–0101
and extends the compliance time for
Model SA 365 N, SA 365 N1, AS 365
N2, and AS 365 N3 helicopters, if
equipped with the fixed parts of the AH
FLIR system installation and that are not
equipped with an EFS with a certain
cabin layout where the passage between
cabin and cockpit is smaller than a Type
4 passage (as defined in EASA AD
2021–0101R1); except helicopters that
have Airbus Helicopters modification
(AH MOD) MC90B73 embodied in
production.
This proposed AD was prompted by
reports of failure of the cockpit doors to
open after ditching with inflated floats
on certain helicopters equipped with an
EFS. EASA advises emergency
evacuation was only possible by
jettisoning the hinged doors from the
inside or by accessing the emergency
exits in the cabin. EASA further advises
that the passage from the cockpit to the
cabin may be impaired on helicopters
with certain interior layouts.
The FAA is proposing this AD to
prevent cockpit doors failing to open
during an emergency evacuation after an
emergency ditching with inflated floats,
which could result in the prevention of
incapacitated occupants exiting the
helicopter during an emergency from
the outside by external rescuers. See
EASA AD 2021–0101R1 for additional
background information.
Related Service Information Under 1
CFR Part 51
EASA AD 2021–0101R1 requires
amending the RFM; installing placards
on the LH and RH side of the helicopter;
and for certain helicopters, modifying
the jettison system by installing an

external handle on the jettison system of
the pilot and co-pilot doors.
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) No.
AS365–52.00.27, Revision 1, dated June
4, 2021 (AS365–52.00.27, Rev 1), which
specifies procedures for installing labels
(placards) on the pilot and co-pilot
doors. AS365–52.00.27, Rev 1, also
specifies procedures for installing an
external handle on the jettison system.
The FAA also reviewed Airbus
Helicopters ASB No. AS365–52.00.29,
Revision 1, dated February 9, 2022, ASB
No. AS365–52.00.29, Revision 0, dated
February 10, 2021, and ASB No. EC155–
52A033, Revision 0, dated September
30, 2020. This service information
specifies procedures for installing labels
(placards) on the pilot and co-pilot
doors.
The FAA also reviewed Airbus
Helicopters Flight Manual (FM) SA 365
N Supplement, SUP.10.4, Normal
Revision (NR) 7, date code 20–40;
Airbus Helicopters FM SA 365 N1

information provides updated
procedures for ditching and emergency
evacuation.
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 these
same type designs.
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
EASA AD 2021–0101R1, described
previously, as incorporated by
reference, except for any differences
PO 00000
Frm 00002
Fmt 4702
Sfmt 4702
identified as exceptions in the
regulatory text of this proposed AD and
except as discussed under ‘‘Differences
Between this Proposed AD and EASA
AD 2021–0101R1.’’
This proposed AD would also require
revising the existing RFM for your
helicopter by updating the normal
procedures section. Incorporating the
RFM revision may be performed by the
owner/operator (pilot) holding at least a
private pilot certificate, and must be
entered into the aircraft records showing
compliance with this AD in accordance
with 14 CFR 43.9(a) and 14 CFR
91.417(a)(2)(v). The record must be
maintained as required by 14 CFR
91.417, 121.380, or 135.439.
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 2021–0101R1 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2021–
0101R1 in its entirety 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 2021–0101R1 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 2021–0101R1.
Service information referenced in EASA
AD 2021–0101R1 for compliance will be
available at www.regulations.gov by
searching for and locating Docket No.
FAA–2022–0988 after the FAA final
rule is published.
Differences Between This Proposed AD
and EASA AD 2021–0101R1
EASA AD 2021–0101R1 allows using
Airbus Helicopters ASB No. AS365–
52.00.27, original issue, dated
November 17, 2020 (including Erratum
to ASB AS365–52.00.27, original issue,
dated January 21, 2021); whereas this
proposed AD would not. This proposed
AD would require using Airbus
Helicopters ASB No. AS365–52.00.27,
Revision 1, dated June 4, 2021, instead.
E:\FR\FM\12AUP1.SGM
12AUP1
Federal Register / Vol. 87, No. 155 / Friday, August 12, 2022 / Proposed Rules
Where paragraph (2) of EASA AD 2021–
0101R1 specifies to ‘‘modify the
helicopter in accordance with the
instructions of Section 3 of the
applicable ASB,’’ this proposed AD
would require using the instructions of
Section 3.B. of the applicable ASB.
EASA AD 2021–0101R1 requires
operators to ‘‘inform all flight crews’’ of
revisions to the RFM, and thereafter to
‘‘operate the helicopter accordingly.’’
However, this proposed AD would not
specifically require those actions. FAA
regulations mandate compliance with
only the operating limitations section of
the flight manual. The flight manual
changes required by this proposed AD
would apply to the emergency
procedures and normal procedures
sections of the existing RFM for your
helicopter. Furthermore, compliance
with such requirements in an AD is
impracticable to demonstrate or track on
an ongoing basis; therefore, a
requirement to operate the aircraft in
such a manner is unenforceable.
Nonetheless, the FAA recommends that
flight crews of the helicopters listed in
the applicability operate in accordance
with the revised emergency procedures
and normal procedures proposed by this
AD.
This proposed AD would allow the
owner/operator (pilot) holding at least a
private pilot certificate to revise the
existing RFM for your helicopter and do
the logbook entry, where as EASA AD
2021–0101R1 does not specify this. This
proposed AD would require these
actions to be entered into the aircraft
records showing compliance with this
AD in accordance with 14 CFR 43.9(a)
and 14 CFR 91.417(a)(2)(v). The record
must be maintained as required by 14
CFR 91.417, 121.380, or 135.439.
For certain helicopters, this proposed
AD would require revising section 4.1,
Normal Procedures, of the existing RFM
for your helicopter to add a check to the
RH and LH Cockpit Door Jettison
Handles, whereas EASA AD 2021–
0101R1 does not require that action.

Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 40
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 existing RFM for your
helicopter would take about 0.25 workhour for an estimated cost of $21 per
helicopter and $840 for the U.S. fleet.
Installing placards on the pilot and
co-pilot doors would take about 1 workhour and parts would cost up to about
VerDate Sep<11>2014
16:27 Aug 11, 2022
Jkt 256001
$138 for an estimated cost of up to $223
per helicopter.
For helicopters with the AH FLIR
system installed, installing placards on
the pilot and co-pilot doors would take
about 0.5 work-hour and parts would
cost about $52 for an estimated cost of
$95 per helicopter.
If required, installing an external
handle on the jettison system would
take about 7 work-hours and parts
would cost about $1,328 for an
estimated cost of $1,923 per helicopter
and $51,921 for the U.S. fleet (27
helicopters).
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some of the
costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
operators.
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

the following new airworthiness
directive:
■
Airbus Helicopters: Docket No. FAA–2022–
0988; Project Identifier MCAI–2021–
00438–R.
(a) Comments Due Date
The FAA must receive comments on this
airworthiness directive (AD) by September
26, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus Helicopters
Model SA–365N, SA–365N1, AS–365N2, AS
365 N3, EC 155B, and EC155B1 helicopters,
certificated in any category.
(d) Subject
Joint Aircraft Service Component (JASC)
Codes: 1100, Placards and Markings; and
5210, Passenger/Crew Doors.
(e) Unsafe Condition
This AD was prompted by reports of failure
of the cockpit doors to open after ditching
with inflated floats on certain helicopters
equipped with an emergency flotation system
(EFS). The FAA is issuing this AD to inform
external rescuers that the cockpit door
jettison function needs to be utilized to
successfully egress incapacitated flight crew
from the cockpit during an emergency when
the EFS is activated. This unsafe condition,
if not addressed, could result in
incapacitated occupants not being able to exit
the helicopter after an emergency ditching
with inflated floats.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC
155B, and EC155B1 helicopters. This proposed AD was prompted by reports
of the cockpit doors failing to open after ditching with inflated
floats on certain helicopters equipped with an emergency flotation
system (EFS). This proposed AD would require revising the existing
Rotorcraft Flight Manual (RFM) for your helicopter, installing
placards, and depending on your model helicopter, modification of the
jettisoning system, 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.
DATES: The FAA must receive comments on this proposed AD by September
26, 2022.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued a series of ADs, with the most recent being
EASA AD 2021-0101R1, dated February 25, 2022 (EASA AD 2021-0101R1), to
correct an unsafe condition for Airbus Helicopters (AH), formerly
Eurocopter, Eurocopter France, Aerospatiale, Sud Aviation, Model SA
[[Page 49774]]
365 N, SA 365 N1, AS 365 N2, AS 365 N3, EC 155 B, and EC 155 B1
helicopters.
EASA initially issued EASA AD 2021-0041, dated January 28, 2021
(EASA AD 2021-0041), for certain Model SA 365 N, SA 365 N1, AS 365 N2,
AS 365 N3, EC 155 B, and EC 155 B1 helicopters, which required
modifying the jettisoning system by installing an external handle on
the jettison system of the pilot and co-pilot doors on certain Model
SA/AS 365 helicopters, installing external instruction placards on the
left-hand (LH) and right-hand (RH) side of the helicopter, and amending
the RFM. EASA later issued EASA AD 2021-0101, dated April 12, 2021
(EASA AD 2021-0101), which superseded EASA AD 2021-0041, to also
address Model AS 365 helicopters with the Airbus Helicopters Forward
Looking InfraRed (AH FLIR) system installed.
EASA AD 2021-0101R1 retains the requirements of EASA AD 2021-0101
and extends the compliance time for Model SA 365 N, SA 365 N1, AS 365
N2, and AS 365 N3 helicopters, if equipped with the fixed parts of the
AH FLIR system installation and that are not equipped with an EFS with
a certain cabin layout where the passage between cabin and cockpit is
smaller than a Type 4 passage (as defined in EASA AD 2021-0101R1);
except helicopters that have Airbus Helicopters modification (AH MOD)
MC90B73 embodied in production.
This proposed AD was prompted by reports of failure of the cockpit
doors to open after ditching with inflated floats on certain
helicopters equipped with an EFS. EASA advises emergency evacuation was
only possible by jettisoning the hinged doors from the inside or by
accessing the emergency exits in the cabin. EASA further advises that
the passage from the cockpit to the cabin may be impaired on
helicopters with certain interior layouts.
The FAA is proposing this AD to prevent cockpit doors failing to
open during an emergency evacuation after an emergency ditching with
inflated floats, which could result in the prevention of incapacitated
occupants exiting the helicopter during an emergency from the outside
by external rescuers. See EASA AD 2021-0101R1 for additional background
information.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0101R1 requires amending the RFM; installing placards
on the LH and RH side of the helicopter; and for certain helicopters,
modifying the jettison system by installing an external handle on the
jettison system of the pilot and co-pilot doors.
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)
No. AS365-52.00.27, Revision 1, dated June 4, 2021 (AS365-52.00.27, Rev
1), which specifies procedures for installing labels (placards) on the
pilot and co-pilot doors. AS365-52.00.27, Rev 1, also specifies
procedures for installing an external handle on the jettison system.
The FAA also reviewed Airbus Helicopters ASB No. AS365-52.00.29,
Revision 1, dated February 9, 2022, ASB No. AS365-52.00.29, Revision 0,
dated February 10, 2021, and ASB No. EC155-52A033, Revision 0, dated
September 30, 2020. This service information specifies procedures for
installing labels (placards) on the pilot and co-pilot doors.
The FAA also reviewed Airbus Helicopters Flight Manual (FM) SA 365
N Supplement, SUP.10.4, Normal Revision (NR) 7, date code 20-40; Airbus
Helicopters FM SA 365 N1 Supplement, SUP.10.4, NR 9, date code 20-40;
Airbus Helicopters FM AS 365 N2 Supplement, SUP.14, NR 6, date code 20-
40; Airbus Helicopters FM AS 365 N3 Supplement, SUP.14, NR 12, date
code 20-28; Airbus Helicopters FM EC 155 B Supplement, SUP.14, NR 7,
date code 20-11; and Airbus Helicopters FM EC 155 B1 Supplement,
SUP.14, NR 8, date code 20-11. This service information provides
updated procedures for ditching and emergency evacuation.
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 these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2021-0101R1, 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 EASA AD 2021-0101R1.''
This proposed AD would also require revising the existing RFM for
your helicopter by updating the normal procedures section.
Incorporating the RFM revision may be performed by the owner/operator
(pilot) holding at least a private pilot certificate, and must be
entered into the aircraft records showing compliance with this AD in
accordance with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). The record
must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
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 2021-0101R1 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2021-0101R1 in its entirety 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 2021-0101R1 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-
0101R1. Service information referenced in EASA AD 2021-0101R1 for
compliance will be available at www.regulations.gov by searching for
and locating Docket No. FAA-2022-0988 after the FAA final rule is
published.
Differences Between This Proposed AD and EASA AD 2021-0101R1
EASA AD 2021-0101R1 allows using Airbus Helicopters ASB No. AS365-
52.00.27, original issue, dated November 17, 2020 (including Erratum to
ASB AS365-52.00.27, original issue, dated January 21, 2021); whereas
this proposed AD would not. This proposed AD would require using Airbus
Helicopters ASB No. AS365-52.00.27, Revision 1, dated June 4, 2021,
instead.
[[Page 49775]]
Where paragraph (2) of EASA AD 2021-0101R1 specifies to ``modify the
helicopter in accordance with the instructions of Section 3 of the
applicable ASB,'' this proposed AD would require using the instructions
of Section 3.B. of the applicable ASB.
EASA AD 2021-0101R1 requires operators to ``inform all flight
crews'' of revisions to the RFM, and thereafter to ``operate the
helicopter accordingly.'' However, this proposed AD would not
specifically require those actions. FAA regulations mandate compliance
with only the operating limitations section of the flight manual. The
flight manual changes required by this proposed AD would apply to the
emergency procedures and normal procedures sections of the existing RFM
for your helicopter. Furthermore, compliance with such requirements in
an AD is impracticable to demonstrate or track on an ongoing basis;
therefore, a requirement to operate the aircraft in such a manner is
unenforceable. Nonetheless, the FAA recommends that flight crews of the
helicopters listed in the applicability operate in accordance with the
revised emergency procedures and normal procedures proposed by this AD.
This proposed AD would allow the owner/operator (pilot) holding at
least a private pilot certificate to revise the existing RFM for your
helicopter and do the logbook entry, where as EASA AD 2021-0101R1 does
not specify this. This proposed AD would require these actions to be
entered into the aircraft records showing compliance with this AD in
accordance with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). The record
must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
For certain helicopters, this proposed AD would require revising
section 4.1, Normal Procedures, of the existing RFM for your helicopter
to add a check to the RH and LH Cockpit Door Jettison Handles, whereas
EASA AD 2021-0101R1 does not require that action.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 40 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 existing RFM for your helicopter would take about 0.25
work-hour for an estimated cost of $21 per helicopter and $840 for the
U.S. fleet.
Installing placards on the pilot and co-pilot doors would take
about 1 work-hour and parts would cost up to about $138 for an
estimated cost of up to $223 per helicopter.
For helicopters with the AH FLIR system installed, installing
placards on the pilot and co-pilot doors would take about 0.5 work-hour
and parts would cost about $52 for an estimated cost of $95 per
helicopter.
If required, installing an external handle on the jettison system
would take about 7 work-hours and parts would cost about $1,328 for an
estimated cost of $1,923 per helicopter and $51,921 for the U.S. fleet
(27 helicopters).
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators.
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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Airbus Helicopters: Docket No. FAA-2022-0988; Project Identifier
MCAI-2021-00438-R.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by September 26, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus Helicopters Model SA-365N, SA-

certificated in any category.
(d) Subject
Joint Aircraft Service Component (JASC) Codes: 1100, Placards
and Markings; and 5210, Passenger/Crew Doors.
(e) Unsafe Condition
This AD was prompted by reports of failure of the cockpit doors
to open after ditching with inflated floats on certain helicopters
equipped with an emergency flotation system (EFS). The FAA is
issuing this AD to inform external rescuers that the cockpit door
jettison function needs to be utilized to successfully egress
incapacitated flight crew from the cockpit during an emergency when
the EFS is activated. This unsafe condition, if not addressed, could
result in incapacitated occupants not being able to exit the
helicopter after an emergency ditching with inflated floats.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, European Union Aviation
[[Page 49776]]
Safety Agency (EASA) AD 2021-0101R1, dated February 25, 2022 (EASA

private pilot certificate, and must be entered into the aircraft
records showing compliance with this AD in accordance with 14 CFR
43.9(a) and 14 CFR 91.417(a)(2)(v). The record must be maintained as
required by 14 CFR 91.417, 121.380, or 135.439.
(4) Where paragraph (2) of EASA AD 2021-0101R1 specifies to
``modify the helicopter in accordance with the instructions of
Section 3 of the applicable ASB,'' for this AD, replace that text
with, ``modify the helicopter in accordance with Section 3.B. in the
Accomplishment Instructions of the applicable ASB.''
(5) Where EASA AD 2021-0101R1 refers to ``ASB AS365-52.00.27''

of equivalent tooling.
(8) Where the service information referenced in paragraph (2) of
EASA AD 2021-0101R1 specifies parking the helicopter in a hangar or
maintenance hangar, this AD does not require those actions.
(9) This AD does not mandate compliance with the ``Remarks''
section of EASA AD 2021-0101R1.
(i) Required Rotorcraft Flight Manual (RFM) Amendment
(1) For Group 2 helicopters as defined in EASA AD 2021-0101R1,
concurrently with accomplishing the actions specified in paragraph
