SUPPLEMENTARY INFORMATION: Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0157, dated July 3, 2019 (EASA AD 2019–0157) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for Airbus Helicopters Model SA330J helicopters, all serial numbers. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Airbus Helicopters Model SA330J helicopters, all serial numbers. The NPRM published in the Federal Register on April 13, 2021 (86 FR 19157). The NPRM was prompted by reports of the failure of the lower bearing cage of the MRH flapping hinges and of the presence of metallic particles at the bottom of a drag hinge. The NPRM proposed to require repetitive inspections of the MRH chip detectors, or for helicopters not equipped with chip detectors, repetitive inspections of the oil for contamination by metallic particles, and corrective actions if necessary, as specified in an EASA AD. The FAA is issuing this AD to address failure of the lower bearing cage of the MRH flapping hinges and presence of metallic particles at the bottom of a drag hinge, which could lead to loss of flapping hinge function, resulting in MRH unbalance and 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 2019–0157 specifies procedures for repetitive inspections of the MRH chip detectors, or for helicopters not equipped with chip detectors, repetitive inspections of the oil for contamination by metallic particles, and corrective actions if necessary. Corrective actions include replacement of the incidence hinge bearings, replacement of the flapping bearing race and bearing or if there is no degradation reinstallation of the bearing race and bearing 180° from the marked position during removal, and replacement of the drag lower bearing race and bearing. 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. The investigation to detect the root cause of the reported failures of the lower bearing cage of the MRH flapping hinges and presence of metallic particles at the bottom of the drag hinge is on-going. Costs of Compliance The FAA estimates that this AD affects 4 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $1,360 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.

SUPPLEMENTARY INFORMATION:

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0157, dated July 3, 2019 (EASA 
AD 2019-0157) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for Airbus Helicopters Model SA330J helicopters, all serial numbers.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Airbus Helicopters 
Model SA330J helicopters, all serial numbers. The NPRM published in the 
Federal Register on April 13, 2021 (86 FR 19157). The NPRM was prompted 
by reports of the failure of the lower bearing cage of the MRH flapping 
hinges and of the presence of metallic particles at the bottom of a 
drag hinge. The NPRM proposed to require repetitive inspections of the 
MRH chip detectors, or for helicopters not equipped with chip 
detectors, repetitive inspections of the oil for contamination by 
metallic particles, and corrective actions if necessary, as specified 
in an EASA AD.
    The FAA is issuing this AD to address failure of the lower bearing 
cage of the MRH flapping hinges and presence of metallic particles at 
the bottom of a drag hinge, which could lead to loss of flapping hinge 
function, resulting in MRH unbalance and 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 2019-0157 specifies procedures for repetitive inspections 
of the MRH chip detectors, or for helicopters not equipped with chip 
detectors, repetitive inspections of the oil for contamination by 
metallic particles, and corrective actions if necessary. Corrective 
actions include replacement of the incidence hinge bearings, 
replacement of the flapping bearing race and bearing or if there is no 
degradation reinstallation of the bearing race and bearing 180[deg] 
from the marked position during removal, and replacement of the drag 
lower bearing race and bearing. 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. The investigation to 
detect the root cause of the reported failures of the lower bearing 
cage of the MRH flapping hinges and presence of metallic particles at 
the bottom of the drag hinge is on-going.

Costs of Compliance

    The FAA estimates that this AD affects 4 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:

    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.

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]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-13-09 Airbus Helicopters: Amendment 39-21614; Docket No. FAA-
2021-0297; Project Identifier 2019-SW-062-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective August 16, 2021.

(b) Affected ADs

    None.

(c) Applicability

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

(d) Subject

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

(e) Reason

    This AD was prompted by reports of the failure of the lower 
bearing cage of the main rotor hub (MRH) flapping hinges and of the 
presence of metallic particles at the bottom of a drag hinge. The 
FAA is issuing this AD to address failure of the lower bearing cage 
of the MRH flapping hinges and presence of metallic particles at the 
bottom of a drag hinge, which could lead to loss of flapping hinge 
function, resulting in MRH unbalance and 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 Union Aviation Safety Agency (EASA) AD 
2019-0157, dated July 3, 2019 (EASA AD 2019-0157).

(h) Exceptions to EASA AD 2019-0157

AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2019-0157 does not apply 
to this AD.
    (3) Where EASA AD 2019-0157 refers to flight hours (FH), this AD 
requires using hours time-in-service.
    (4) Although the service information referenced in EASA AD 2019-
0157 specifies to discard certain parts, this AD requires removing 
those 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 the helicopter is operated during the day under visual 
flight rules with no passengers are onboard.

    (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,
