Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2023–0030, dated February 2, 2023 (EASA AD 2023–0030) (also referred to as the MCAI), to correct an unsafe condition on Airbus Helicopters Model EC 225 LP VerDate Sep<11>2014 16:28 Dec 20, 2024 Jkt 265001 helicopters, except helicopters having Airbus Helicopters modification MC29201 embodied in production. The MCAI states missing electrical bonding was identified on a certain partnumbered search light installed on some Model EC 225 LP helicopters. The MCAI further states that the location where the search light is installed is an area that could get struck by lightning, which, in case of a lightning strike, could lead to potential total loss of electrical distribution, with loss of electrically supplied systems, and subsequent reduced control of the helicopter. The FAA is proposing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–2663. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2023–0030 requires installing an electrical bonding braid modification for a certain partnumbered search light under the sponson. EASA AD 2023–0030 also prohibits installing that part-numbered search light from being installed unless its requirements are met. 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 products have been approved by the aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2023–0030, 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 MCAI.’’ Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 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 2023–0030 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2023–0030 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 2023–0030 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 2023–0030. Material referenced in EASA AD 2023– 0030 for compliance will be available at regulations.gov under Docket No. FAA– 2024–2663 after the FAA final rule is published. Differences Between This Proposed AD and the MCAI The MCAI allows a +10% tolerance to the calendar compliance time to install the electrical bonding braid modification, whereas this proposed AD would not allow that tolerance. If the insulation resistance value is 8 or more ohms as a result of the continuity test that is specified in the material referenced in EASA AD 2023–0030, this proposed AD would require accomplishing corrective action in accordance with a method approved by the FAA, EASA, or Airbus Helicopters’ EASA Design Organization Approval, whereas the MCAI and the material referenced in the MCAI are not specific about the continuity test. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 9 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. Installing an electrical bonding braid modification would take 14 work-hours and parts would cost $16,370 for an estimated cost of $17,560 per helicopter and up to $158,040 for the U.S. fleet. Performing a continuity test would take a minimal amount of time for a nominal cost. Depending on the results, E:\FR\FM\23DEP1.SGM 23DEP1 Federal Register / Vol. 89, No. 246 / Monday, December 23, 2024 / Proposed Rules Authority: 49 U.S.C. 106(g), 40113, 44701. corrective action could vary significantly from helicopter to helicopter. The FAA has no data to determine the costs to accomplish the corrective action. § 39.13 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. khammond on DSK9W7S144PROD with PROPOSALS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 1. The authority citation for part 39 continues to read as follows: ■ VerDate Sep<11>2014 16:28 Dec 20, 2024 Jkt 265001 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus Helicopters: Docket No. FAA–2024– 2663; Project Identifier MCAI–2023– 00200–R. (a) Comments Due Date The FAA must receive comments on this airworthiness directive (AD) by February 6, 2025. (b) Affected ADs None. (c) Applicability This AD applies to Airbus Helicopters Model EC225LP helicopters, certificated in any category, as identified in European Union Aviation Safety Agency AD 2023– 0030, dated February 2, 2023 (EASA AD 2023–0030). (d) Subject Joint Aircraft System Component (JASC) Code: 1420, electrical connectors; and 2497, electrical power system wiring. (e) Unsafe Condition This AD was prompted by the identification of missing electrical bonding on additional and optional search lights.

(f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023– 0030. Note 1 to paragraph (g): Appendix 4 of Airbus Helicopters Alert Service Bulletin No. EC225–33A018, dated December 15, 2023, which is referenced in EASA AD 2023–0030, identifies helicopter configurations (righthand column of the table) by helicopter serial number (left-hand column of the table). (h) Exceptions to EASA AD 2023–0030 (1) Where EASA AD 2023–0030 requires compliance in terms of flight hours, this AD requires using hours time-in-service. (2) Where EASA AD 2023–0030 refers to its effective date, this AD requires using the effective date of this AD. (3) Where Note 1 of EASA AD 2023–0030 specifies that a tolerance of +10% may be applied to the calendar compliance time specified in paragraph (1) of EASA AD 2023– 0030, this AD does not allow that tolerance. (4) Where the material referenced in EASA AD 2023–0030 specifies discarding parts, this PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 104467 AD requires removing those parts from service. (5) This AD requires replacing text as specified in paragraphs (h)(5)(i) though (v) of this AD. (i) Where the material referenced in EASA AD 2023–0030 specifies to ‘‘do the electrical bonding,’’ this AD requires replacing that text with ‘‘install the electrical bonding braid.’’ (ii) Where the material referenced in EASA AD 2023–0030 specifies to ‘‘bond the labels ‘‘741VN’’ and ‘‘742VN’’ of the set of labels (8) as close as possible from the equipment (SECTION A–A and B–B),’’ this AD requires replacing that text with ‘‘apply labels ‘‘741VN’’ and ‘‘742VN’’ of the set of labels (8) directly adjacent to the grounding point as depicted in Figure 6, Section A–A and Section B–B.’’ (iii) Where the material referenced in EASA AD 2023–0030 specifies to ‘‘remove and keep,’’ this AD requires replacing that text with, ‘‘remove.’’ (iv) Where the material referenced in EASA AD 2023–0030 specifies to ‘‘locate the hole (A) in accordance to the position,’’ this AD requires replacing that text with ‘‘determine the position of hole (A) in Figure 4, Detail B.’’ (v) Where the material referenced in EASA AD 2023–0030 specifies to paint strip the hole on ‘‘the both face,’’ this AD requires replacing the text ‘‘the both face’’ with ‘‘each side.’’ (6) Where the material referenced in EASA AD 2023–0030 specifies to do a continuity test, if the insulation resistance value is 8 or more ohms as a result of the continuity test, this AD requires, before further flight, accomplishing corrective action in accordance with a method approved by the Manager, International Validation Branch, FAA; or EASA; or Airbus Helicopters’ EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. (7) This AD does not adopt the ‘‘Remarks’’ section of EASA AD 2023–0030. (i) No Reporting Requirement Although the material referenced in EASA AD 2023–0030 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) Alternative Methods of Compliance (AMOCs) (1) The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate.

RIN 2120-AA64


Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Helicopters Model EC225LP helicopters. This proposed 
AD was prompted by the identification of missing electrical bonding on 
a certain part-numbered additional and optional search light (search 
light). This proposed AD would require installing an electrical bonding 
braid modification and prohibit installing that part-numbered search 
light unless the modification is done. These actions are specified in a 
European Union Aviation Safety Agency (EASA) AD, which is proposed for 
incorporation by reference. The FAA is proposing this AD to address the 
unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by February 6, 2025.

for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2023-0030, dated February 2, 2023 
(EASA AD 2023-0030) (also referred to as the MCAI), to correct an 
unsafe condition on Airbus Helicopters Model EC 225 LP helicopters, 
except helicopters having Airbus Helicopters modification MC29201 
embodied in production. The MCAI states missing electrical bonding was 
identified on a certain part-numbered search light installed on some 
Model EC 225 LP helicopters. The MCAI further states that the location 
where the search light is installed is an area that could get struck by 
lightning, which, in case of a lightning strike, could lead to 
potential total loss of electrical distribution, with loss of 
electrically supplied systems, and subsequent reduced control of the 
helicopter.
    The FAA is proposing this AD to address the unsafe condition on 
these products. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2024-2663.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2023-0030 requires installing an electrical bonding braid 
modification for a certain part-numbered search light under the 
sponson. EASA AD 2023-0030 also prohibits installing that part-numbered 
search light from being installed unless its requirements are met.
    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 products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI referenced above. The FAA is issuing this NPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2023-0030, 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 MCAI.''

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 2023-0030 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0030 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 2023-0030 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 2023-
0030. Material referenced in EASA AD 2023-0030 for compliance will be 
available at regulations.gov under Docket No. FAA-2024-2663 after the 
FAA final rule is published.

Differences Between This Proposed AD and the MCAI

    The MCAI allows a +10% tolerance to the calendar compliance time to 
install the electrical bonding braid modification, whereas this 
proposed AD would not allow that tolerance. If the insulation 
resistance value is 8 or more ohms as a result of the continuity test 
that is specified in the material referenced in EASA AD 2023-0030, this 
proposed AD would require accomplishing corrective action in accordance 
with a method approved by the FAA, EASA, or Airbus Helicopters' EASA 
Design Organization Approval, whereas the MCAI and the material 
referenced in the MCAI are not specific about the continuity test.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 9 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.
    Installing an electrical bonding braid modification would take 14 
work-hours and parts would cost $16,370 for an estimated cost of 
$17,560 per helicopter and up to $158,040 for the U.S. fleet.
    Performing a continuity test would take a minimal amount of time 
for a nominal cost. Depending on the results,

[[Page 104467]]

corrective action could vary significantly from helicopter to 
helicopter. The FAA has no data to determine the costs to accomplish 
the corrective 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.
    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-2024-2663; Project Identifier 
MCAI-2023-00200-R.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by February 6, 2025.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Helicopters Model EC225LP helicopters, 
certificated in any category, as identified in European Union 
Aviation Safety Agency AD 2023-0030, dated February 2, 2023 (EASA AD 
2023-0030).

(d) Subject

    Joint Aircraft System Component (JASC) Code: 1420, electrical 
connectors; and 2497, electrical power system wiring.

(e) Unsafe Condition

    This AD was prompted by the identification of missing electrical 
bonding on additional and optional search lights. The FAA is issuing 
this AD to prevent a lightning current evacuating to the aircraft 
structure. In the event of a lightning strike, the unsafe condition, 
if not addressed, could result in potential total loss of electrical 
distribution, with loss of electrically supplied systems, and 
subsequent reduced control of the helicopter.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraphs (h) and (i) of this AD: Comply 
with all required actions and compliance times specified in, and in 
accordance with, EASA AD 2023-0030.

    Note 1 to paragraph (g): Appendix 4 of Airbus Helicopters Alert 
Service Bulletin No. EC225-33A018, dated December 15, 2023, which is 
referenced in EASA AD 2023-0030, identifies helicopter 
configurations (right-hand column of the table) by helicopter serial 
number (left-hand column of the table).

(h) Exceptions to EASA AD 2023-0030

    (1) Where EASA AD 2023-0030 requires compliance in terms of 
flight hours, this AD requires using hours time-in-service.
    (2) Where EASA AD 2023-0030 refers to its effective date, this 
AD requires using the effective date of this AD.
    (3) Where Note 1 of EASA AD 2023-0030 specifies that a tolerance 
of +10% may be applied to the calendar compliance time specified in 
paragraph (1) of EASA AD 2023-0030, this AD does not allow that 
tolerance.
    (4) Where the material referenced in EASA AD 2023-0030 specifies 
discarding parts, this AD requires removing those parts from 
service.
    (5) This AD requires replacing text as specified in paragraphs 
(h)(5)(i) though (v) of this AD.
    (i) Where the material referenced in EASA AD 2023-0030 specifies 
to ``do the electrical bonding,'' this AD requires replacing that 
text with ``install the electrical bonding braid.''
    (ii) Where the material referenced in EASA AD 2023-0030 
specifies to ``bond the labels ``741VN'' and ``742VN'' of the set of 
labels (8) as close as possible from the equipment (SECTION A-A and 
B-B),'' this AD requires replacing that text with ``apply labels 
``741VN'' and ``742VN'' of the set of labels (8) directly adjacent 
to the grounding point as depicted in Figure 6, Section A-A and 
Section B-B.''
    (iii) Where the material referenced in EASA AD 2023-0030 
specifies to ``remove and keep,'' this AD requires replacing that 
text with, ``remove.''
    (iv) Where the material referenced in EASA AD 2023-0030 
specifies to ``locate the hole (A) in accordance to the position,'' 
this AD requires replacing that text with ``determine the position 
of hole (A) in Figure 4, Detail B.''
    (v) Where the material referenced in EASA AD 2023-0030 specifies 
to paint strip the hole on ``the both face,'' this AD requires 
replacing the text ``the both face'' with ``each side.''
    (6) Where the material referenced in EASA AD 2023-0030 specifies 
to do a continuity test, if the insulation resistance value is 8 or 
more ohms as a result of the continuity test, this AD requires, 
before further flight, accomplishing corrective action in accordance 
with a method approved by the Manager, International Validation 
Branch, FAA; or EASA; or Airbus Helicopters' EASA Design 
Organization Approval (DOA). If approved by the DOA, the approval 
must include the DOA-authorized signature.
    (7) This AD does not adopt the ``Remarks'' section of EASA AD 
2023-0030.

(i) No Reporting Requirement

    Although the material referenced in EASA AD 2023-0030 specifies 
to submit certain information to the manufacturer, this AD does not 
include that requirement.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
