2022-14-51 AIRBUS HELICOPTERS: Amendment 39-22124; Docket No. FAA-2022-0878; Project Identifier MCAI-2022-00873-R.
(a) EFFECTIVE DATE

    The FAA  issued Emergency  Airworthiness Directive  (AD) 2022-14-51 on
    July 1, 2022, directly to  affected owners and operators. As  a result
    of such  actual notice,  that AD  was effective  for those  owners and
    operators  on the  date it  was provided.  This AD  contains the  same
    requirements as that emergency AD  and, for those who did  not receive
    actual notice, is effective on August 3, 2022.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to Airbus Helicopters  Model EC225LP helicopters, cer-
    tificated in any category,  with main rotor hub (MRH) sleeve part num-
    ber 332A31-3071-00 installed.

(d) SUBJECT

    Joint Aircraft Service Component (JASC) Code: 6200, Main Rotor System.

(e) UNSAFE CONDITION

    This AD was prompted by a report  of a cracked MRH sleeve.  The FAA is
    issuing this AD to detect corrosion or cracking in an MRH sleeve.  The
    unsafe condition, if not addressed,  could result in failure of an MRH
    sleeve, loss of a main rotor blade and subsequent loss of the helicop-
    ter.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) REQUIRED ACTIONS

(1) Before further flight  after the effective date  of this AD,  visually
    inspect the "Specific area" of each MRH sleeve as depicted in Figure 3
    of Airbus Helicopters  Emergency  Alert  Service  Bulletin No. 62A017,
    Revision 0,  dated June 30, 2022  (ASB 62A017),  for flaking and paint
    touch-up.

(2) As a result of the actions required by paragraph (g)(1) of this AD, if
    there is no flaking or paint touch-up, no further action is  required.
    If there  is any  flaking or  paint touch-up,  before further  flight,
    visually inspect the "Specific area" of the MRH sleeve as depicted  in
    Figure 3 of ASB 62A017 for a crack.

(3) As a result of the actions required by paragraph (g)(2) of this AD, if
    there is a  crack, before further  flight, remove the  MRH sleeve from
    service and  replace it  with an  airworthy part.  If there  is not  a
    crack, within 15  hours time-in-service (TIS)  or 3 months,  whichever
    occurs first  after accomplishing  the actions  required by  paragraph
    (g)(1) of this AD, use  high-frequency eddy current (HFEC) to  inspect
    the "Specific area" of the MRH  sleeve as depicted in Figure 3  of ASB
    62A017 for  a crack.  This HFEC  inspection must  be accomplished by a
    Level  II  or  III  inspector  certified  in  the  eddy  current fault
    detection method in the Aeronautics Sector according to the EN4179  or
    NAS410 standard.

(4) As a result of the actions required by paragraph (g)(3) of this AD, if
    there is a crack,  before  further  flight, remove the MRH sleeve from
    service and replace it  with an airworthy part.  If  there  is  not  a
    crack,  before further flight,  chemically strip and fluorescent pene-
    trant inspect (FPI)  the "Specific area" of the MRH sleeve as depicted
    in Figure 3 of ASB 62A017 for corrosion.

(i) If there is corrosion as a result of the actions required by the intro
    -ductory text of paragraph (g)(4)  of this AD,  before further flight,
    accomplish the actions  required  by  paragraph (g)(4)(i)(A) or (B) of
    this AD.

(A) Remove the corrosion by hand  using 120-grit abrasive cloth,  followed
    by 400-grit abrasive cloth.  After removing the corrosion,  perform an
    FPI of each affected area to inspect for corrosion, and accomplish the
    actions required by paragraph (g)(4)(i)(A)(1) or (2) of this AD.

(1) If there is corrosion, before further flight,  remove  the  MRH sleeve
    from service  and  replace  it  with an airworthy part or repair it in
    accordance with a method  approved by the Manager,  General Aviation &
    Rotorcraft Section,  International Validation Branch, FAA; or European
    Union Aviation Safety Agency (EASA) or Airbus Helicopters' EASA Design
    Organization Approval (DOA). If approved by the DOA, the approval must
    include the DOA-authorized signature.

(2) If there is no corrosion, before further flight,  completely  dry  the
    MRH sleeve and apply a protective coating,  primer,  and paint protec-
    tion. Following application, within 15 hours TIS and thereafter at in-
    tervals not to exceed 15 hours TIS,  use HFEC to inspect the "Specific
    area" of the MRH sleeve  as  depicted  in Figure 3 of ASB 62A017 for a
    crack.  This HFEC inspection must be accomplished by a Level II or III
    inspector certified  in the eddy current fault detection method in the
    Aeronautics Sector according  to  the  EN4179  or  NAS410 standard. If
    there is a crack, before  further  flight,  remove the MRH sleeve from
    service and replace it  with an airworthy part.  Accomplishment of the
    HFEC inspections  with  no  detected  cracks  after 75 hours TIS since
    applying the coating, primer,  and paint protection constitutes a ter-
    minating action for the repetitive inspections  required by this para-
    graph.

(B) If the corrosion  cannot be removed by hand  as specified in paragraph
    (g)(4)(i)(A) of this AD, before further flight, remove the MRH  sleeve
    from service and  replace it with  an airworthy part  or repair it  in
    accordance with a method approved  by the Manager, General Aviation  &
    Rotorcraft Section, International Validation Branch, FAA; or EASA;  or
    Airbus Helicopters'  EASA DOA.  If approved  by the  DOA, the approval
    must include the DOA-authorized signature.

(ii) If there is no corrosion  as a result of the actions  required by the
     introductory text of paragraph (g)(4)  of  this  AD,  before  further
     flight, apply primer and paint protection.

(5) As an option to the actions  required by paragraph (g)(4)  of this AD,
    if there is not a crack, accomplish the actions required by paragraphs
    (g)(5)(i) and (ii) of this AD.

(i) Before further flight, apply primer and paint protection.  If there is
    any area with flaking paint,  you  may  apply  only varnish instead of
    primer and paint protection on each flaking paint area.

(ii) Within 15 hours TIS after accomplishing the actions required by para-
     graph (g)(5)(i) of this AD and thereafter at intervals not to  exceed
     15 hours TIS, HFEC inspect the  "Specific area" of the MRH sleeve  as
     depicted in Figure 3 of ASB 62A017 for a crack. This HFEC  inspection
     must be accomplished by a Level II or III inspector certified in  the
     eddy  current  fault  detection  method  in  the  Aeronautics  Sector
     according to  the EN4179  or NAS410  standard. If  there is  a crack,
     before further flight, remove the MRH sleeve from service and replace
     it with an airworthy part.

(6) As of the effective date of this AD,  do  not  install  an  MRH sleeve
    identified in paragraph  (c) of this  AD on any  helicopter unless the
    actions required  by paragraphs  (g)(1) and  (2) of  this AD have been
    accomplished.

(h) SPECIAL FLIGHT PERMITS

    A special flight permit may be issued in accordance with 14 CFR 21.197
    and 21.199 provided that there are no passengers onboard  and there is
    no crack or corrosion in an MRH sleeve.

(i) 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 (j)(1)  of this AD. Information may  be
    emailed to: 9-AVS-AIR-730-AMOC@faa.gov.

(2) Before using any approved AMOC,  notify your appropriate principal in-

SUPPLEMENTARY INFORMATION:

Background

On July 1, 2022, the FAA issued Emergency AD 2022-14-51, which
requires certain inspections and corrective actions for Airbus
Helicopters Model EC225LP helicopters with MRH sleeve part number (P/N)
332A31-3071-00 installed. The FAA sent the emergency AD to all known
U.S. owners and operators of these helicopters. That action was
prompted by EASA Emergency AD 2022-0130-E, dated June 30, 2022 (EASA AD
2022-0130-E), issued by EASA, which is the Technical Agent for the
Member States of the European Union, to correct an unsafe condition for
Airbus Helicopters (AH), formerly Eurocopter, Model EC 225 LP
helicopters. EASA advises of a crack in an MRH sleeve that
investigation determined was a fatigue crack that had initiated from a
corrosion pit located in an area with chipped paint. This condition, if
not addressed, could result in failure of an MRH sleeve, loss of a main
rotor blade, and subsequent loss of the helicopter.
Accordingly, EASA AD 2022-0130-E requires initial one-time detailed
visual inspections of MRH sleeve P/N 332A31-3071-00 and depending on
the results, follow-on repetitive inspections and corrective actions.

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 emergency AD. The FAA is issuing 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.

Related Service Information Under 1 CFR Part 51

The FAA reviewed Airbus Helicopters Emergency Alert Service
Bulletin No. 62A017, Revision 0, dated June 30, 2022, which applies to
Model EC225LP and EC725AP helicopters. This service information
specifies procedures for one-time detailed visual inspections of a
certain area (identified as ``Specific area'' in Figure 3 of the
service information) of MRH sleeve P/N 332A31-3071-00. Depending on the
one-time inspection results, this service information specifies
procedures for follow-on inspections, which include eddy current
inspections, and chemical stripping and fluorescent penetrant
inspections; and corrective actions, which include applying primer and
paint protection, removing corrosion, applying a protective coating,
contacting Airbus Helicopters for corrective action, and removing and
returning the MRH sleeve to Airbus Helicopters.
This service information 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.

AD Requirements


This AD requires visually inspecting the ``Specific area'' of each
MRH sleeve P/N 332A31-3071-00 for flaking and paint touch-up. If there
is any flaking or paint touch-up, this AD requires visually inspecting
the ``Specific area'' of the MRH sleeve for a crack.
As a result of the visual inspection, if there is a crack, this AD
requires removing the MRH sleeve from service and installing an
airworthy part. If there is not a crack, this AD requires an inspector
with a certain qualification using high-frequency eddy current (HFEC)
to inspect the ``Specific area'' of the MRH sleeve for a crack.
As a result of the HFEC, if there is a crack, this AD requires
removing the MRH sleeve from service and installing an airworthy part.
If there is not a crack, this AD requires chemically stripping and
fluorescent penetrant inspecting (FPI) the ``Specific area'' of the MRH
sleeve for corrosion.
As a result of the FPI, if there is corrosion, this AD requires
removing the corrosion by hand and repeating the FPI of each affected
area to inspect for corrosion, and depending on the subsequent results,
removing the MRH sleeve from service and installing an airworthy part;
or drying the MRH sleeve, applying a protective coating, primer, and
paint protection, and having an inspector with a certain qualification
using HFEC repetitively inspect the ``Specific area'' of the MRH sleeve
for a crack. If there is a crack, this AD requires removing the MRH
sleeve from service and installing an airworthy part. However, if the
corrosion cannot be removed by hand, this AD requires removing the MRH
sleeve from service and installing an airworthy part or repairing the
MRH sleeve in accordance with a certain approved method.
As a result of the first FPI, if there is no corrosion, this AD
requires applying primer and paint protection.
As an option to the first FPI and its follow-on actions, if there
is not a crack, this AD allows applying primer and paint protection or,
for any areas with flaking paint, applying only varnish instead of
primer and paint protection on each flaking paint area; and having an
inspector with a certain qualification using HFEC to repetitively
inspect the ``Specific area'' of the MRH sleeve for a crack. If there
is a crack, this AD requires removing the MRH sleeve from service and
installing an airworthy part.
This AD also prohibits installing an MRH sleeve unless specified
one-time visual inspections have been accomplished.

Differences Between This AD and the EASA AD

If there is corrosion in an MRH sleeve, EASA AD 2022-0130-E
requires contacting Airbus Helicopters for approved repair
instructions, whereas this AD requires removing the MRH sleeve from
service or repairing the MRH sleeve in accordance with a certain
approved method.

Justification for Immediate Adoption and Determination of the Effective
Date


Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that required the immediate adoption of
Emergency AD 2022-14-51, issued on July 1, 2022, to all known U.S.
owners and operators of these helicopters. The FAA found that the risk
to the flying public justified waiving notice and comment prior to
adoption of this rule because failure of an affected part could result
in loss of the helicopter and injury to its occupants and persons on
the ground. In light of this, the initial actions required by this AD
must be accomplished before further flight and certain follow-on
actions required by this AD must be accomplished within 15 hours time-
in-service or 3 months, whichever occurs first after accomplishing the
initial actions. These compliance times are shorter than the time
necessary for the public to comment and for publication of the final
rule. These conditions still exist, therefore, notice and opportunity
for prior public comment are impracticable and contrary to the public
interest pursuant to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forego notice and
comment.

Comments Invited

The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2022-0878; Project Identifier MCAI-
2022-00873-R'' at the beginning of your comments. The most helpful
comments reference a specific portion of the final rule, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this final rule because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
https://www.regulations.gov, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.

Confidential Business Information

CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this AD contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this AD, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this AD. Submissions containing CBI should be sent to Kristi
Bradley, Program Manager, COS Program Management Section, Operational
Safety Branch, Compliance & Airworthiness Division, FAA, 10101 Hillwood
Pkwy., Fort Worth, TX 76177; telephone (817) 222-5110; email
kristin.bradley@faa.gov. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.

Regulatory Flexibility Act

The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.

Costs of Compliance

The FAA estimates that this AD affects 33 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates the following costs to comply with
this AD.
Visually inspecting an affected MRH sleeve for flaking and paint
touch-up takes about 0.5 work-hour for an estimated cost of $43 per MRH
sleeve and up to $7,095 for the U.S. fleet (with up to five affected
MRH sleeves per helicopter).
If required, visually inspecting each MRH sleeve for a crack takes
about 0.5 work-hour for an estimated cost of $43 per MRH sleeve.
Accomplishing an HFEC takes about 0.5 work-hour for an estimated cost
of $43 per MRH sleeve, per inspection cycle. Chemically stripping and
accomplishing an FPI takes about 8 work-hours for an estimated cost of
$680 per MRH sleeve, per inspection cycle.
Removing corrosion and applying protective coating, primer, and
paint protection takes a minimal amount of time and parts cost a
nominal amount. Replacing an MRH sleeve takes about 4 work-hours and
parts cost about $102,371 for an estimated cost of $102,711 per MRH
sleeve. The FAA has no way of determining the costs pertaining to any
necessary repairs that are required to be done with an approved method.

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

This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national Government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866, and
(2) Will not affect intrastate aviation in Alaska.
