SUPPLEMENTARY INFORMATION: Discussion 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 EC130B4 and EC130T2 helicopters. The NPRM published in the Federal Register on March 11, 2020 (85 FR 14180). The NPRM was prompted by a report that a changed manufacturing process for the TRB was implemented, affecting the structural characteristics of the blades and generating a new part number for these blades. The NPRM proposed to require re-identifying each affected TRB having a certain part number and serial number and establishing a life limit for the new part numbers. The NPRM also proposed to prohibit installation of any affected TRB identified with the old part number on any helicopter. The FAA is issuing this AD to ensure the new part number (P/ N) TRBs do not exceed their life limit, which could lead to loss of the TRB and E:\FR\FM\23JNR1.SGM 23JNR1 37550 Federal Register / Vol. 85, No. 121 / Tuesday, June 23, 2020 / Rules and Regulations subsequent loss of control of the helicopter. The European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0182, dated August 28, 2018 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Helicopters Model EC130B4 and EC130T2 helicopters. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0238. 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 Airbus Helicopters has issued Alert Service Bulletin EC130–04A007, Revision 0, dated July 18, 2018 (‘‘ASB EC130–04A007’’). This service information describes procedures for reidentifying a TRB with P/N 350A333002.02 for certain serial numbers, as specified in ASB EC130– 04A007. 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. Difference Between This Proposed AD and the MCAI or Service Information EASA AD 2018–0182 specifies to replace TRBs having P/N 350A333002.05. However, this part number is not installed on in-service helicopters and is not addressed in Airbus Helicopters ASB EC130–04A007. Therefore, this AD does not require replacing TRBs having P/N 350A333002.05. Costs of Compliance The FAA estimates that this AD affects 253 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 1 work-hour × $85 per hour = $85 .............................................................................................. $0 ** $85 $21,505 * * The FAA has received no definitive data that would enable the agency to provide cost estimates for the additional applicable maintenance instructions specified in this AD. ** The FAA has received no definitive data on the parts costs for required actions. 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. jbell on DSKJLSW7X2PROD with RULES 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 VerDate Sep<11>2014 16:24 Jun 22, 2020 Jkt 250001 responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION:

Discussion

    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 EC130B4 and EC130T2 helicopters. The NPRM published in the 
Federal Register on March 11, 2020 (85 FR 14180). The NPRM was prompted 
by a report that a changed manufacturing process for the TRB was 
implemented, affecting the structural characteristics of the blades and 
generating a new part number for these blades. The NPRM proposed to 
require re-identifying each affected TRB having a certain part number 
and serial number and establishing a life limit for the new part 
numbers. The NPRM also proposed to prohibit installation of any 
affected TRB identified with the old part number on any helicopter. The 
FAA is issuing this AD to ensure the new part number (P/N) TRBs do not 
exceed their life limit, which could lead to loss of the TRB and

[[Page 37550]]

subsequent loss of control of the helicopter.
    The European Aviation Safety Agency (now European Union Aviation 
Safety Agency) (EASA), which is the Technical Agent for the Member 
States of the European Union, has issued EASA AD 2018-0182, dated 
August 28, 2018 (referred to after this as ``the MCAI''), to correct an 
unsafe condition for all Airbus Helicopters Model EC130B4 and EC130T2 
helicopters. You may examine the MCAI in the AD docket on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0238.

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

    Airbus Helicopters has issued Alert Service Bulletin EC130-04A007, 
Revision 0, dated July 18, 2018 (``ASB EC130-04A007''). This service 
information describes procedures for re-identifying a TRB with P/N 
350A333002.02 for certain serial numbers, as specified in ASB EC130-
04A007. 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.

Difference Between This Proposed AD and the MCAI or Service Information

    EASA AD 2018-0182 specifies to replace TRBs having P/N 
350A333002.05. However, this part number is not installed on in-service 
helicopters and is not addressed in Airbus Helicopters ASB EC130-
04A007. Therefore, this AD does not require replacing TRBs having P/N 
350A333002.05.

Costs of Compliance

    The FAA estimates that this AD affects 253 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency to provide cost estimates for the
  additional applicable maintenance instructions specified in this AD.
** The FAA has received no definitive data on the parts costs for required actions.

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 above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 (AD):

2020-12-09 Airbus Helicopters: Amendment 39-21144; Docket No. FAA-
2020-0238; Product Identifier 2018-SW-072-AD.

(a) Effective Date

    This AD is July 28, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus Helicopters Model EC130B4 and 
EC130T2 helicopters, certificated in any category.

(d) Subject

    Joint Aircraft Service Component (JASC) Code 6410, Tail rotor 
blade.

(e) Reason

    This AD was prompted by a report that a new manufacturing 
process for the tail rotor blades (TRBs) has been implemented, 
affecting the structural characteristics of the TRB and generating a 
new part number (P/N) for these blades. It was determined that a new 
life limit is needed for the new P/N TRBs. The FAA is issuing this 
AD to ensure the new P/N TRBs do not exceed their life limit, which 
could lead to loss of the TRB and subsequent loss of control of the 
helicopter.

[[Page 37551]]

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Definition of an Affected Part for the Re-identification and
