Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022–0104, dated June 9, 2022 (EASA AD 2022– 0104), to correct an unsafe condition on Airbus Helicopters Model EC 225 LP helicopters. This proposed AD was prompted by a report of water in the oil of an MGB, due to an incorrect installation of the upper M/R mast cover plate. According to Airbus Helicopters, a detailed inspection of the MGB showed corrosion on the M/R mast and inside the MGB. The upper M/R mast cover plate was deformed. Also, according to Airbus Helicopters, a different M/R mast had damaged upper stop screws installed, also due to an incorrect installation. The FAA is issuing this proposed AD to prevent water in the MGB oil. The unsafe condition, if not addressed, could result in corrosion of the M/R mast and inside the MGB, degradation of the MGB, degradation of the upper stops assembly, failure of a critical part, and subsequent loss of control of the helicopter. You may examine EASA AD 2022– 0104 in the AD docket at regulations.gov under Docket No. FAA–2024–1297. Related Service Information Under 1 CFR Part 51 EASA AD 2022–0104 requires replacing each M/R mast upper stops assembly screw, except those marked with ‘‘BC’’ on the screw head. For certain helicopters, EASA AD 2022– 0104 requires inspecting a certain partnumbered M/R mast cover plate and depending on the results, replacing the cover plate and accomplishing an additional inspection. For those same certain helicopters, EASA AD 2022– 0104 also requires accomplishing MGB oil analyses and, depending on the results, accomplishing an additional inspection. Depending on the results of the additional inspection following the M/R mast cover plate inspection or MGB oil analyses, EASA AD 2022–0104 requires replacing the MGB. As an option, EASA AD 2022–0104 allows replacing the MGB as an acceptable alternative method to comply with the required MGB oil sample analyses. Lastly, EASA AD 2022–0104 prohibits installing M/R mast upper stops assembly screws—except those marked E:\FR\FM\16MYP1.SGM 16MYP1 42822 Federal Register / Vol. 89, No. 96 / Thursday, May 16, 2024 / Proposed Rules with ‘‘BC’’ on the screw head, M/R masts with an affected M/R mast upper stops assembly screw installed, and used M/R mast cover plates on any helicopter. EASA AD 2022–0104 also prohibits installing an affected M/R mast unless its required inspections are done. 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. ddrumheller on DSK120RN23PROD with PROPOSALS1 Other Related Service Information The FAA also reviewed Airbus Helicopters No. EC225–62A016, Revision 1, dated February 28, 2023. This service information specifies procedures for inspecting the M/R mast upper stops assembly screws to determine if they’re marked with ‘‘BC’’ on the screw head and depending on the results, replacing those screws one by one. This service information also specifies procedures for checking the flatness of the M/R mast cover plate and, depending on the results, removing and discarding that cover plate, installing a flat cover plate, draining the MGB, writing to Airbus Helicopters to do a detailed MGB inspection, and removing the M/R mast. Depending on the detailed MGB inspection results, this service information specifies filling the MGB with oil and installing the M/ R mast; or replacing the MGB with an airworthy MGB, sending the removed MGB to an approved D-level center for repair, and installing the M/R mast. This service information also specifies procedures for collecting an MGB oil sample and sending the sample to an Airbus Helicopters approved laboratory for water content analysis. Depending on the analysis results, this service information specifies draining the MGB, writing to Airbus Helicopters to do a detailed MGB inspection, and removing the M/R mast. Depending on the detailed MGB inspection results, this service information specifies filling the MGB with oil and installing the M/R mast; or replacing the MGB with an airworthy MGB, sending the removed MGB to an approved D-level center for repair, and installing the M/R mast. 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 VerDate Sep<11>2014 17:04 May 15, 2024 Jkt 262001 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 2022–0104, 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 2022–0104 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022–0104 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 2022–0104 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 2022–0104. Service information referenced in EASA AD 2022–0104 for compliance will be available at regulations.gov under Docket No. FAA–2024–1297 after the FAA final rule is published. Differences Between This Proposed AD and the EASA AD For certain helicopters, EASA AD 2022–0104 specifies sending oil samples to an Airbus Helicopters approved laboratory for an analysis of the water content, whereas this proposed AD would require sending the main gearbox oil sample for water content analysis. Additionally, for those helicopters, EASA AD 2022–0104 specifies taking and analyzing the second MGB oil sample within 110 FH or 3 months after the initial oil sample, whereas this proposed AD would require collecting PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 the second main gearbox oil sample and sending it for water content analysis within 110 hours time-in-service or 3 months after accomplishing the initial instance of those actions, whichever occurs later. Depending on the results of the cover plate inspection or an oil sample analysis, EASA AD 2022–0104 specifies contacting Airbus Helicopters to request to accomplish a detailed inspection, which shall be accomplished by authorized Airbus Helicopters staff and the Airbus Helicopters qualified staff identify any discrepancies, whereas this proposed AD would require a detailed inspection, which must define what is considered a discrepancy and be done in accordance with a method approved by the FAA, EASA, or Airbus Helicopters’ EASA Design Organization Approval. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 32 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. Replacing the M/R mast upper stops assembly screws (up to 10 screws) would take up to approximately 0.5 work-hour and parts would cost up to approximately $250 (for 10 screws) for an estimated cost of up to $293 per helicopter and $9,376 for the U.S. fleet. For certain helicopters, inspecting the M/R mast cover plate would take approximately 0.5 work-hour for an estimated cost of $43 per helicopter and up to $1,376 for the U.S. fleet. Collecting an MGB oil sample and sending the MGB oil sample for water content analysis, which is considered a reporting requirement in this proposed AD, would take approximately 1.5 work-hours (0.5 work-hour for collecting and 1 work-hour for sending) for an estimated cost of $128 per helicopter and up to $4,096 for the U.S. fleet, per instance. If required, replacing the M/R mast cover plate would take approximately 2 work-hours and parts would cost approximately $276 for an estimated cost of $446 per helicopter. The detailed inspection that may be needed could vary significantly from helicopter to helicopter. The FAA has no data to determine the costs to accomplish the detailed inspection or the number of helicopters that may need it. Replacing an MGB would take approximately 40 work-hours and parts would cost approximately $998,595 (overhauled) for an estimated cost of $1,001,995 per helicopter. E:\FR\FM\16MYP1.SGM 16MYP1 Federal Register / Vol. 89, No. 96 / Thursday, May 16, 2024 / Proposed Rules Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056. Public reporting for this collection of information is estimated to take approximately 1.5 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. ddrumheller on DSK120RN23PROD with PROPOSALS1 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: VerDate Sep<11>2014 17:04 May 15, 2024 Jkt 262001 (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. 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.

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 all Airbus Helicopters Model EC225LP helicopters. This proposed AD 
was prompted by a report of water in the oil of a main gearbox (MGB). 
This AD requires replacing certain main rotor (M/R) mast upper stops 
assembly screws. This proposed AD would also require inspecting certain 
M/R mast

[[Page 42821]]

cover plates and accomplishing MGB oil analyses and, depending on the 
results, replacing the M/R mast cover plate, accomplishing an 
additional inspection, or replacing the MGB. This proposed AD would 
also prohibit installing certain M/R mast upper stops assembly screws, 
M/R masts with an affected M/R mast upper stops assembly screw 
installed, or used M/R mast cover plates on any helicopter. Lastly, 
this proposed AD would prohibit installing affected M/R masts unless 
the inspections are 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 proposed AD by July 1, 
2024.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0104, dated June 9, 2022 (EASA 
AD 2022-0104), to correct an unsafe condition on Airbus Helicopters 
Model EC 225 LP helicopters.
    This proposed AD was prompted by a report of water in the oil of an 
MGB, due to an incorrect installation of the upper M/R mast cover 
plate. According to Airbus Helicopters, a detailed inspection of the 
MGB showed corrosion on the M/R mast and inside the MGB. The upper M/R 
mast cover plate was deformed. Also, according to Airbus Helicopters, a 
different M/R mast had damaged upper stop screws installed, also due to 
an incorrect installation. The FAA is issuing this proposed AD to 
prevent water in the MGB oil. The unsafe condition, if not addressed, 
could result in corrosion of the M/R mast and inside the MGB, 
degradation of the MGB, degradation of the upper stops assembly, 
failure of a critical part, and subsequent loss of control of the 
helicopter.
    You may examine EASA AD 2022-0104 in the AD docket at 
regulations.gov under Docket No. FAA-2024-1297.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0104 requires replacing each M/R mast upper stops 
assembly screw, except those marked with ``BC'' on the screw head. For 
certain helicopters, EASA AD 2022-0104 requires inspecting a certain 
part-numbered M/R mast cover plate and depending on the results, 
replacing the cover plate and accomplishing an additional inspection. 
For those same certain helicopters, EASA AD 2022-0104 also requires 
accomplishing MGB oil analyses and, depending on the results, 
accomplishing an additional inspection. Depending on the results of the 
additional inspection following the M/R mast cover plate inspection or 
MGB oil analyses, EASA AD 2022-0104 requires replacing the MGB. As an 
option, EASA AD 2022-0104 allows replacing the MGB as an acceptable 
alternative method to comply with the required MGB oil sample analyses.
    Lastly, EASA AD 2022-0104 prohibits installing M/R mast upper stops 
assembly screws--except those marked

[[Page 42822]]

with ``BC'' on the screw head, M/R masts with an affected M/R mast 
upper stops assembly screw installed, and used M/R mast cover plates on 
any helicopter. EASA AD 2022-0104 also prohibits installing an affected 
M/R mast unless its required inspections are done.
    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 No. EC225-62A016, Revision 
1, dated February 28, 2023. This service information specifies 
procedures for inspecting the M/R mast upper stops assembly screws to 
determine if they're marked with ``BC'' on the screw head and depending 
on the results, replacing those screws one by one. This service 
information also specifies procedures for checking the flatness of the 
M/R mast cover plate and, depending on the results, removing and 
discarding that cover plate, installing a flat cover plate, draining 
the MGB, writing to Airbus Helicopters to do a detailed MGB inspection, 
and removing the M/R mast. Depending on the detailed MGB inspection 
results, this service information specifies filling the MGB with oil 
and installing the M/R mast; or replacing the MGB with an airworthy 
MGB, sending the removed MGB to an approved D-level center for repair, 
and installing the M/R mast.
    This service information also specifies procedures for collecting 
an MGB oil sample and sending the sample to an Airbus Helicopters 
approved laboratory for water content analysis. Depending on the 
analysis results, this service information specifies draining the MGB, 
writing to Airbus Helicopters to do a detailed MGB inspection, and 
removing the M/R mast. Depending on the detailed MGB inspection 
results, this service information specifies filling the MGB with oil 
and installing the M/R mast; or replacing the MGB with an airworthy 
MGB, sending the removed MGB to an approved D-level center for repair, 
and installing the M/R mast.

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 2022-0104, 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 2022-0104 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0104 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 2022-0104 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 2022-
0104. Service information referenced in EASA AD 2022-0104 for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-1297 after the FAA final rule is published.

Differences Between This Proposed AD and the EASA AD

    For certain helicopters, EASA AD 2022-0104 specifies sending oil 
samples to an Airbus Helicopters approved laboratory for an analysis of 
the water content, whereas this proposed AD would require sending the 
main gearbox oil sample for water content analysis. Additionally, for 
those helicopters, EASA AD 2022-0104 specifies taking and analyzing the 
second MGB oil sample within 110 FH or 3 months after the initial oil 
sample, whereas this proposed AD would require collecting the second 
main gearbox oil sample and sending it for water content analysis 
within 110 hours time-in-service or 3 months after accomplishing the 
initial instance of those actions, whichever occurs later. Depending on 
the results of the cover plate inspection or an oil sample analysis, 
EASA AD 2022-0104 specifies contacting Airbus Helicopters to request to 
accomplish a detailed inspection, which shall be accomplished by 
authorized Airbus Helicopters staff and the Airbus Helicopters 
qualified staff identify any discrepancies, whereas this proposed AD 
would require a detailed inspection, which must define what is 
considered a discrepancy and be done in accordance with a method 
approved by the FAA, EASA, or Airbus Helicopters' EASA Design 
Organization Approval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 32 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.
    Replacing the M/R mast upper stops assembly screws (up to 10 
screws) would take up to approximately 0.5 work-hour and parts would 
cost up to approximately $250 (for 10 screws) for an estimated cost of 
up to $293 per helicopter and $9,376 for the U.S. fleet.
    For certain helicopters, inspecting the M/R mast cover plate would 
take approximately 0.5 work-hour for an estimated cost of $43 per 
helicopter and up to $1,376 for the U.S. fleet. Collecting an MGB oil 
sample and sending the MGB oil sample for water content analysis, which 
is considered a reporting requirement in this proposed AD, would take 
approximately 1.5 work-hours (0.5 work-hour for collecting and 1 work-
hour for sending) for an estimated cost of $128 per helicopter and up 
to $4,096 for the U.S. fleet, per instance.
    If required, replacing the M/R mast cover plate would take 
approximately 2 work-hours and parts would cost approximately $276 for 
an estimated cost of $446 per helicopter. The detailed inspection that 
may be needed could vary significantly from helicopter to helicopter. 
The FAA has no data to determine the costs to accomplish the detailed 
inspection or the number of helicopters that may need it. Replacing an 
MGB would take approximately 40 work-hours and parts would cost 
approximately $998,595 (overhauled) for an estimated cost of $1,001,995 
per helicopter.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1.5 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
