SUPPLEMENTARY INFORMATION: Electronic Availability This document and additional information concerning OFAC are available on OFAC’s website (www.treasury.gov/ofac). Background On August 12, 1993, in accordance with section 6(j) of the Export Administration Act of 1979, then codified at 50 U.S.C. App. 2405(j), the Secretary of State designated Sudan as a State Sponsor of Terrorism (58 FR 52523, October 8, 1993). On August 22, 1996, OFAC promulgated the Terrorism List Governments Sanctions Regulations, 31 CFR part 596 (61 FR 43462, August 23, 1996) (the ‘‘Regulations’’), to implement section 321 of the Antiterrorism and Effective Death Penalty Act of 1996 (18 U.S.C. 2332d). On July 1, 1998, OFAC issued the Sudanese Sanctions Regulations, 31 CFR part 538 (63 FR 35809, July 1, 1998) (SSR), to implement Executive Order (E.O.) 13067 of November 3, 1997, ‘‘Blocking Sudanese Government Property and Prohibiting Transactions With Sudan’’ (62 FR 59989, November 5, 1997), in which the President declared a national emergency with respect to the policies and actions of the Government of Sudan. To deal with that threat, E.O. 13067 imposed comprehensive trade sanctions with respect to Sudan and blocked all property and interests in property of the Government of Sudan in the United States or within the possession or control of United States persons. The SSR were amended on various occasions to, among other things, implement further Executive orders, including E.O. 13412 of October 13, 2006, ‘‘Blocking Property of and Prohibiting Transactions with the Government of Sudan’’ (71 FR 61369, October 17, 2006), and add additional authorizations. Effective October 12, 2017, sections 1 and 2 of E.O. 13067 and all of E.O. 13412 were revoked, pursuant to E.O. 13761 of January 13, 2017, ‘‘Recognizing Positive Actions by the Government of Sudan and Providing for the Revocation of Certain Sudan-Related Sanctions’’ (82 FR 5331, January 18, 2017), as amended by E.O. 13804 of July 11, 2017, ‘‘Allowing Additional Time for Recognizing Positive Actions by the Government of Sudan and Amending E:\FR\FM\20MYR1.SGM 20MYR1

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Model SA330J helicopters. This AD was prompted by 
the failure of a second stage planet gear installed in the main gearbox 
(MGB). This AD requires 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, as specified in a European Aviation Safety Agency 
(now European Union Aviation Safety Agency) (EASA) AD, which is 
incorporated by reference. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective June 24, 2021.

SUPPLEMENTARY INFORMATION:

Background

    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.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus Helicopters 
Model SA330J helicopters. The NPRM published in the Federal Register on 
March 2, 2021 (86 FR 12127). The NPRM was prompted by the failure of a 
second stage planet gear installed in the MGB. The NPRM proposed to 
require 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, as 
specified in an EASA AD.
    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. See the MCAI for 
additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2018-0272 specifies 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.

Interim Action

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

[[Page 27272]]

Costs of Compliance

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

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
           Labor cost                   Parts cost            product
------------------------------------------------------------------------
40 work-hours x $85 per hour =   $600,000 (overhauled)..        $603,400
 $3,400.
------------------------------------------------------------------------

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

directive:

2021-10-10 Airbus Helicopters: Amendment 39-21543; Docket No. FAA-
2021-0105; Project Identifier MCAI-2020-01422-R.

(a) Effective Date

    This airworthiness directive (AD) is effective June 24, 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

[[Page 27273]]

    (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, 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,
