Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0272, dated December 13, 2018 (EASA AD 2018–0272) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model SA330J helicopters. This proposed AD was prompted by the failure of a second stage planet gear installed in the MGB of an Airbus Helicopters Model EC225LP helicopter. Airbus Helicopters Model SA330J helicopters have a similar design, therefore, these models may be subject to the unsafe condition revealed on the Model EC225LP helicopter. The FAA is proposing this AD to address failure of E:\FR\FM\02MRP1.SGM 02MRP1 12128 Federal Register / Vol. 86, No. 39 / Tuesday, March 2, 2021 / Proposed Rules the unsafe condition described previously is likely to exist or develop in other products of the same type design. a second stage planet gear installed in the MGB, which could result in failure of the MGB and subsequent loss of control of the helicopter. See the MCAI for additional background information. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2018–0272, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD. Related Service Information Under 1 CFR Part 51 EASA AD 2018–0272 describes procedures for repetitively inspecting the MGB particle detector and the MGB bottom housing (oil sump) for metal particles, analyzing any metal particles that are found, and replacement of the MGB if necessary. 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 and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the FAA evaluated all the relevant information and determined Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2018–0272 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2018–0272 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 the EASA AD 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 the EASA AD. Service information specified in EASA AD 2018–0272 that is required for compliance with EASA AD 2018–0272 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0105 after the FAA final rule is published. Interim Action The FAA considers this proposed AD interim action. If final action is later identified, the FAA might consider further rulemaking then. Costs of Compliance The FAA estimates that this proposed AD affects 15 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 5 work-hours × $85 per hour = $425 .......................................................................................... $0 $425 $6,375 The FAA estimates the following costs to do any necessary on-condition replacements that would be required based on the results of any required actions. The FAA has no way of determining the number of helicopters that might need these on-condition replacements: ESTIMATED COSTS OF ON-CONDITION ACTIONS Parts cost 40 work-hours × $85 per hour = $3,400 ..................................... $600,000 (overhauled) ............................................................... Authority for This Rulemaking jbell on DSKJLSW7X2PROD with PROPOSALS Cost per product Labor cost 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 VerDate Sep<11>2014 16:34 Mar 01, 2021 Jkt 253001 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 PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 $603,400 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) Will not affect intrastate aviation in Alaska, and E:\FR\FM\02MRP1.SGM 02MRP1 Federal Register / Vol. 86, No. 39 / Tuesday, March 2, 2021 / Proposed Rules (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0272, dated December 13, 2018 
(EASA AD 2018-0272) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Model SA330J helicopters.
    This proposed AD was prompted by the failure of a second stage 
planet gear installed in the MGB of an Airbus Helicopters Model EC225LP 
helicopter. Airbus Helicopters Model SA330J helicopters have a similar 
design, therefore, these models may be subject to the unsafe condition 
revealed on the Model EC225LP helicopter. The FAA is proposing this AD 
to address failure of

[[Page 12128]]

a second stage planet gear installed in the MGB, which could result in 
failure of the MGB and subsequent loss of control of the helicopter. 
See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2018-0272 describes procedures for repetitively inspecting 
the MGB particle detector and the MGB bottom housing (oil sump) for 
metal particles, analyzing any metal particles that are found, and 
replacement of the MGB if necessary. 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 and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2018-0272, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2018-0272 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2018-0272 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 the EASA AD 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 the EASA AD. Service information specified 
in EASA AD 2018-0272 that is required for compliance with EASA AD 2018-
0272 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0105 after the FAA 
final rule is published.

Interim Action

    The FAA considers this proposed AD interim action. If final action 
is later identified, the FAA might consider further rulemaking then.

Costs of Compliance

    The FAA estimates that this proposed AD affects 15 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

    The FAA estimates the following costs to do any necessary on-
condition replacements that would be required based on the results of 
any required actions. The FAA has no way of determining the number of 
helicopters that might need these on-condition replacements:

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) Will not affect intrastate aviation in Alaska, and

[[Page 12129]]

    (3) Will 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

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-2021-0105; Project Identifier 
MCAI-2020-01422-R.

(a) Comments Due Date

    The FAA must receive comments by April 16, 2021.

(b) Affected Airworthiness Directives (ADs)

    None.

(c) Applicability

    This AD applies to all Airbus Helicopters Model SA330J 
helicopters, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 6320, Main Rotor 
Gearbox.

(e) Reason

    This AD was prompted by a failure of a second stage planet gear 
installed in the main gearbox (MGB). The FAA is issuing this AD to 
address failure of an MGB second stage planet gear, which could 
result in failure of the MGB and subsequent loss of control of the 
helicopter.

(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 Aviation Safety Agency (now European Union 
Aviation Safety Agency) (EASA) AD 2018-0272, dated December 13, 2018 
(EASA AD 2018-0272).

(h) Exceptions to EASA AD 2018-0272

    (1) Where EASA AD 2018-0272 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where EASA AD 2018-0272 refers to March 30, 2018 (the 
effective date of EASA AD 2018-0065, dated March 23, 2018), this AD 
requires using the effective date of this AD.
    (3) The ``Remarks'' section of EASA AD 2018-0272 does not apply 
to this AD.
    (4) Where EASA AD 2018-0272 refers to flight hours (FH), this AD 
requires using hours time-in-service.
    (5) Where paragraph (1) of EASA AD 2018-0272 specifies to 
inspect the MGB particle detector ``in accordance with the 
instructions of Section 3 of the ASB'' for this AD use ``in 
accordance with the instructions in step 3.B.2.a. of the ASB.''
    (6) Where paragraph (2) of EASA AD 2018-0272 specifies to 
inspect the MGB bottom housing (oil sump) ``in accordance with the 
instructions of Section 3 of the ASB'' for this AD use ``in 
accordance with the instructions in step 3.B.2.b. of the ASB.''
    (7) Where the service information referenced in EASA AD 2018-
0272 specifies to perform a metallurgical analysis and contact the 
manufacturer if unsure about the characterization of the particles 
collected, this AD does not require contacting the manufacturer to 
determine the characterization of the particles collected.
    (8) Although the service information referenced in EASA AD 2018-
0272 specifies that if any 16NCD13 particles are found to contact 
the manufacturer and send a 1-liter sample of oil to the 
manufacturer, this AD does not require that action.
    (9) Although the service information referenced in EASA AD 2018-
0272 specifies returning certain parts to the manufacturer, this AD 
does not require that action.
    (10) Where EASA AD 2018-0272 specifies actions be done after the 
last flight of the day or ``ALF,'' this AD requires doing those 
actions before the first flight of the day.
    (11) Although the service information referenced in EASA AD 
2018-0272 specifies discarding certain parts, this AD requires 
removing the parts from service.

(i) Special Flight Permit

    Special flight permits may be issued in accordance with 14 CFR 
21.197 and 21.199 to operate the helicopter to a location where the 
helicopter can be modified (if the operator elects to do so), 
provided that the helicopter is operated during the day, under 
visual flight rules, and with no passengers onboard.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Strategic Policy Rotorcraft Section, FAA, has 
the authority to approve AMOCs for this AD, if requested using the
