SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD with RULES Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2015–25–04, Amendment 39–18342 (80 FR 76381, December 9, 2015), (AD 2015–25–04). AD 2015–25–04 applied to Agusta S.p.A (now Leonardo S.p.a.) Model A109A and A109A II helicopters. The NPRM published in the Federal Register on March 8, 2021 (86 FR 13232). In the NPRM, the FAA proposed to retain the initial and repetitive 25 hours time-inservice (TIS) inspections required by AD 2015–25–04 and depending on the inspection results, continue to require replacing the slider with an airworthy slider. Additionally, the NPRM proposed to require, within 800 hours TIS, removing slider part number (P/N) 109–0130–11–7 from service and replacing it with a modified slider P/N 109–0130–11–7 marked with an ‘‘R’’ after the serial number, which would provide a terminating action for the repetitive inspections. Finally, the NPRM proposed to prohibit installing certain sliders on any helicopter. The NPRM was prompted by EASA AD 2020–0142, dated June 25, 2020 (EASA AD 2020–0142), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Leonardo S.p.a. Model A109A and A109A II helicopters with a certain part-numbered slider. EASA AD 2020–0142 supersedes EASA AD 2015–0097, dated June 1, 2015 (EASA AD 2015–0097). EASA AD 2015– 0097 was issued after unusual play was detected on a certain part-numbered slider. EASA advised in EASA AD 2015–0097 that investigation revealed excessive wear of the slider broaching at the point of contact with the tail rotor shaft but that the cause of the excessive play had not been determined. EASA AD 2015–25–04 prompted the FAA to issue AD 2015–25–04. EASA now advises that further investigation results identified the reason for the excessive play was a manufacturing issue. Accordingly, EASA AD 2020–0142 retains the repetitive inspections for a VerDate Sep<11>2014 16:17 May 13, 2021 Jkt 253001 certain part-numbered slider, requires replacing a certain part-numbered slider with a modified slider, and provides a terminating action for the repetitive inspections. Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion 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 AD. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters as proposed in the NPRM; however, the paragraphs have been restructured to meet current formatting requirements, and the responsible office for approving Alternative Methods of Compliance has been revised. These changes will neither increase the scope of the AD nor increase the economic burden on any operator. Related Service Information The FAA reviewed Leonardo Helicopters Alert Service Bulletin No. 109–149, Revision A, dated May 18, 2020, which specifies procedures for repetitively inspecting the slider for play. This service information also references procedures for replacing the affected slider with a modified slider. Differences Between This AD and the EASA AD The EASA AD requires replacing the affected part-numbered slider within 60 months, while this AD requires replacing the affected slider within 800 hours TIS. Costs of Compliance The FAA estimates that this AD affects 147 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting the slider for play takes about 1 work-hour for an estimated cost of $85 per helicopter and $12,495 for the U.S. fleet per inspection cycle. Replacing a slider takes about 10 workhours and parts cost about $4,068 for an estimated cost of $4,918 per helicopter and $722,946 for the U.S. fleet. According to Leonardo Helicopters’ service information, some of the costs of PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 this AD may be covered under warranty, thereby reducing the cost impact on affected persons. The FAA does not control warranty coverage by Leonardo Helicopters. Accordingly, the FAA has included all costs in this cost estimate. 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.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2015-25-04 
for Agusta S.p.A (now Leonardo S.p.a.) Model A109A and A109A II 
helicopters. AD 2015-25-04 required inspecting the slider assembly 
pitch control (slider) for play and replacing the slider if the play 
exceeds certain limits. This AD was prompted by further investigation 
that led to the determination that the play was caused by a 
manufacturing issue. This AD retains certain requirements of AD 2015-
25-04, requires replacing certain part-numbered sliders as a 
terminating action for the inspections, and prohibits installing the 
affected part on any helicopter. The FAA is issuing this AD to address 
the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2015-25-04, Amendment 39-18342 (80 FR 
76381, December 9, 2015), (AD 2015-25-04). AD 2015-25-04 applied to 
Agusta S.p.A (now Leonardo S.p.a.) Model A109A and A109A II 
helicopters. The NPRM published in the Federal Register on March 8, 
2021 (86 FR 13232). In the NPRM, the FAA proposed to retain the initial 
and repetitive 25 hours time-in-service (TIS) inspections required by 
AD 2015-25-04 and depending on the inspection results, continue to 
require replacing the slider with an airworthy slider. Additionally, 
the NPRM proposed to require, within 800 hours TIS, removing slider 
part number (P/N) 109-0130-11-7 from service and replacing it with a 
modified slider P/N 109-0130-11-7 marked with an ``R'' after the serial 
number, which would provide a terminating action for the repetitive 
inspections. Finally, the NPRM proposed to prohibit installing certain 
sliders on any helicopter. The NPRM was prompted by EASA AD 2020-0142, 
dated June 25, 2020 (EASA AD 2020-0142), issued by EASA, which is the 
Technical Agent for the Member States of the European Union, to correct 
an unsafe condition for Leonardo S.p.a. Model A109A and A109A II 
helicopters with a certain part-numbered slider. EASA AD 2020-0142 
supersedes EASA AD 2015-0097, dated June 1, 2015 (EASA AD 2015-0097). 
EASA AD 2015-0097 was issued after unusual play was detected on a 
certain part-numbered slider. EASA advised in EASA AD 2015-0097 that 
investigation revealed excessive wear of the slider broaching at the 
point of contact with the tail rotor shaft but that the cause of the 
excessive play had not been determined. EASA AD 2015-25-04 prompted the 
FAA to issue AD 2015-25-04. EASA now advises that further investigation 
results identified the reason for the excessive play was a 
manufacturing issue. Accordingly, EASA AD 2020-0142 retains the 
repetitive inspections for a certain part-numbered slider, requires 
replacing a certain part-numbered slider with a modified slider, and 
provides a terminating action for the repetitive inspections.

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    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 AD. The FAA reviewed the relevant 
data and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these helicopters as proposed in the NPRM; however, the 
paragraphs have been restructured to meet current formatting 
requirements, and the responsible office for approving Alternative 
Methods of Compliance has been revised. These changes will neither 
increase the scope of the AD nor increase the economic burden on any 
operator.

Related Service Information

    The FAA reviewed Leonardo Helicopters Alert Service Bulletin No. 
109-149, Revision A, dated May 18, 2020, which specifies procedures for 
repetitively inspecting the slider for play. This service information 
also references procedures for replacing the affected slider with a 
modified slider.

Differences Between This AD and the EASA AD

    The EASA AD requires replacing the affected part-numbered slider 
within 60 months, while this AD requires replacing the affected slider 
within 800 hours TIS.

Costs of Compliance

    The FAA estimates that this AD affects 147 helicopters of U.S. 
Registry. The FAA estimates that operators may incur the following 
costs in order to comply with this AD. Labor costs are estimated at $85 
per work-hour.
    Inspecting the slider for play takes about 1 work-hour for an 
estimated cost of $85 per helicopter and $12,495 for the U.S. fleet per 
inspection cycle. Replacing a slider takes about 10 work-hours and 
parts cost about $4,068 for an estimated cost of $4,918 per helicopter 
and $722,946 for the U.S. fleet.
    According to Leonardo Helicopters' service information, some of the 
costs of this AD may be covered under warranty, thereby reducing the 
cost impact on affected persons. The FAA does not control warranty 
coverage by Leonardo Helicopters. Accordingly, the FAA has included all 
costs in this cost estimate.

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.
