PROPOSED AD AIRBUS HELICOPTERS: Docket No. FAA-2022-0804; Project Identifier MCAI-2022-00081-R.
(a) COMMENTS DUE DATE

    The FAA must receive comments on this airworthiness directive (AD)  by
    August 15, 2022.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD  applies to  all  Airbus Helicopters  Model  AS332C, AS332C1,
    AS332L, and AS332L1 helicopters, certificated in any category.

(d) SUBJECT

    Joint  Aircraft  Service Component  (JASC)  Code: 1400,  Miscellaneous
    Hardware.

(e) UNSAFE CONDITION

    This AD was prompted by review of maintenance instructions that showed
    conflicting methods of recording torque cycles for certain parts.  The
    FAA  is  issuing  this AD  to  address  under-calculated torque  cycle
    accumulations and prevent a part from remaining in service beyond  its
    fatigue life.  The unsafe condition, if not addressed, could result in
    failure of a part and subsequent loss of control of the helicopter.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready 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, European Union Aviation Safety Agency (EASA) AD  2022
    -0012, dated January 24, 2022 (EASA AD 2022-0012).

(h) EXCEPTIONS TO EASA AD 2022-0012

(1) Where EASA AD 2022-0012  defines "the ASB" as "AH Alert Service Bulle-
    tin (ASB) AS332-01.00.76,"  for  this  AD replace that definition with
    "Airbus Helicopters Alert Service Bulletin No. AS332-01.00.76 Revision
    1, dated March 8, 2022."

(2) Where EASA AD 2022-0012  references flight hours (FH)  and the service
    information  referenced  in  EASA AD 2022-0012  specifies  life  limit
    thresholds in terms of FH, this AD requires using total hours time-in-
    service.

(3) Where EASA AD 2022-0012 refers to its effective date, this AD requires
    using the effective date of this AD.

(4) This AD does not mandate paragraph (3) of EASA AD 2022-0012;  instead,
    for this AD,  within 30 days after the effective date of this AD,  in-
    corporate into maintenance records  required by 14 CFR 91.417(a)(2) or
    135.439(a)(2),  as applicable  for your helicopter,  the  actions  and
    associated thresholds and intervals, including life limits and mainte-
    nance tasks, specified in the Appendix, section 4., of Airbus Helicop-
    ters Alert Service Bulletin No. AS332-01.00.76 Revision 1, dated March
    8, 2022. After the action required by this paragraph has been done, no
    alternative actions and associated thresholds and intervals, including
    life limits,  may be used unless the actions or intervals are approved
    as an alternative method of compliance (AMOC)  in accordance  with the
    procedures specified in paragraph (k)(1) of this AD.

(5) This AD does not mandate compliance with the "Remarks" section of EASA
    AD 2022-0012.

(i) NO REPORTING REQUIREMENT

    Although the service information referenced in EASA AD 2022-0012 spec-
    ifies to submit certain information to the manufacturer,  this AD does
    not include that requirement.

(j) SPECIAL FLIGHT PERMIT

    Special flight permits are prohibited.

(k) 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. If  sending information  directly to  the manager  of the
    International  Validation  Branch, send  it  to the  attention  of the
    person identified in paragraph (l)(2)  of this AD. Information may  be
    emailed to: 9-AVS-AIR-730-AMOC@faa.gov.

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 AS332C, AS332C1, AS332L, and AS332L1
helicopters. This proposed AD was prompted by review of maintenance
instructions that showed conflicting methods of recording torque cycles
for certain parts. This proposed AD would require recalculating the
torque cycles of certain parts, updating log cards, and replacing those
parts before exceeding their recalculated service life limits (life
limits); removing certain other parts from service; and applying an
operational restriction on 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.

DATES: The FAA must receive comments on this proposed AD by August 15,
2022.

Background

EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0012, dated January 24, 2022
(EASA AD 2022-0012), to correct an unsafe condition for Airbus
Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale,
Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters.
This proposed AD was prompted by review of maintenance instructions
that showed conflicting methods of recording torque cycles for certain
parts. The FAA is proposing this AD to address under-calculated torque
cycle accumulations and prevent a part from remaining in service beyond
its fatigue life. The unsafe condition, if not addressed, could result in failure
of a part and subsequent loss of control of the helicopter. See EASA AD
2022-0012 for additional background information.

Related Service Information Under 1 CFR Part 51

EASA AD 2022-0012 requires recalculating the torque cycles of
certain affected parts, updating log cards, and replacing those parts
before exceeding their recalculated service life limits. EASA AD 2022-
0012 also requires removing certain other affected parts from service
and prohibits installing those parts. Lastly, EASA AD 2022-0012 applies
an operational restriction to certain affected parts.
The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB)
No. AS332-01.00.76, Revision 1, dated March 8, 2022 (ASB AS332-
01.00.76, Rev 1). This service information specifies procedures for
determining the corrected accumulated torque cycles and updating the
log cards for certain parts, new life limits expressed in torque
cycles, and new procedures for counting torque cycles.
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 these same type designs.

Proposed AD Requirements in This NPRM

This proposed AD would require accomplishing the actions specified
in EASA AD 2022-0012, 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 2022-0012 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2022-0012 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 2022-0012 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-
0012. Service information referenced in EASA AD 2022-0012 for
compliance will be available at https://www.regulations.gov by
searching for and locating Docket No. FAA-2022-0804 after the FAA final
rule is published.

ADs Mandating Airworthiness Limitations

The FAA has previously mandated airworthiness limitations by
mandating each airworthiness limitation task (e.g., inspections and
replacements (life limits)) as an AD requirement or issuing ADs that
require revising the airworthiness limitations section (ALS) of the
existing maintenance manual or instructions for continued airworthiness
to incorporate new or revised inspections and life limits. This
proposed AD, however, would require operators to incorporate into
maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2),
as applicable for your helicopter, the requirements (airworthiness
limitations) specified in service information required by a CAA AD. The
FAA does not intend this as a substantive change. For these ADs, the
ALS requirements for operators are the same but are complied with
differently. Requiring the incorporation of the new ALS requirements
into the maintenance records, rather than requiring individual ALS
tasks (e.g., repetitive inspections and replacements), requires
operators to record AD compliance once after updating the maintenance
records, rather than after every time the ALS task is completed.

Differences Between This Proposed AD and the EASA AD

EASA AD 2022-0012 allows using Airbus Helicopters ASB No. AS332-
01.00.76, Revision 0, dated December 16, 2021, for corrective actions;
whereas this proposed AD would not and would instead require using ASB
AS332-01.00.76, Rev 1. EASA AD 2022-0012 requires replacing each
affected part before exceeding its re-calculated life limit; whereas
this proposed AD would require, within 30 days after the effective date
of the AD, incorporating the re-calculated life limits into maintenance
records required by 14 CFR 91.417(a)(2) or 135.439(a)(2), as applicable
for your helicopter.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would
affect 7 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.
Recalculating the torque cycles and updating maintenance records
would take about 4 work-hours for an estimated cost of about $340 per
helicopter and $2,380 for the U.S. fleet. Incorporating actions and
associated thresholds and intervals, including life limits and
maintenance tasks, into maintenance records, would require about 2
work-hours for a cost of $170 per helicopter and a cost of $1,190 for
the U.S. fleet. Replacing a main rotor shaft would take about 40 work-
hours and parts would cost about $175,684 for an estimated cost of
$179,084. Replacing a main gearbox flexible mounting plate support
would take about 80 work-hours and parts would cost about $57,457 for
an estimated cost of $64,257.

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.
