Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. khammond on DSKJM1Z7X2PROD with PROPOSALS Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0096, dated March 31, 2021 (EASA AD 2021– 0096), to correct an unsafe condition for Leonardo S.p.A. Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A.; and AgustaWestland Philadelphia Corporation, formerly Agusta Aerospace Corporation, Model A119 and AW119MKII helicopters, all serial numbers. This proposed AD was prompted by reports of abnormal play on the collective torque tube on two Model AW119 MKII helicopters. Investigations revealed that these events were due to an erroneous manufacturing process, affecting certain collective torque tube assemblies. The affected batch numbers were identified. Leonardo S.p.a. Model A119 helicopters are similar in design and may be subject to the same unsafe condition revealed on the Model AW119 MKII helicopters. The FAA is proposing this AD to address abnormal play on the collective torque tube, which could result in reduced control of the helicopter, resulting in a forced landing and consequent damage to the helicopter and injury to occupants. See VerDate Sep<11>2014 16:23 Jul 19, 2021 Jkt 253001 EASA AD 2021–0096 for additional background information. FAA’s Determination 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 is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0096 requires repetitive inspections of the affected torque tube assemblies for any deficiency (i.e., any play) by marking the torque tube assembly and the collar and applying specific loads to determine if there is any play; and replacement of any affected part that has any play with a serviceable part. EASA AD 2021–0096 also requires the eventual replacement of any affected part with a serviceable part, and specifies that replacement of an affected part on a helicopter constitutes terminating action for the repetitive inspections for that helicopter. 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. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2021–0096, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under ‘‘Differences Between this Proposed AD and the EASA AD.’’ Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use certain civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2021–0096 will be incorporated by reference in the FAA final rule. This proposed AD PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 38243 would, therefore, require compliance EASA AD 2021–0096 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 EASA AD 2021–0096 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 EASA AD 2021–0096. Service information specified in EASA AD 2021–0096 that is required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0572 after the FAA final rule is published. Differences Between This Proposed AD and the EASA AD EASA AD 2021–0096 supersedes EASA AD 2019–0057, dated March 20, 2019 (EASA AD 2019–0057). The Group 1 helicopters identified in both EASA AD 2021–0096 and EASA AD 2019– 0057 are helicopters with collective stick torque tube assemblies having part number (P/N) 109–0011–03–105 and batch number 823207 or earlier. Paragraph (1) of EASA AD 2021–0096 addresses Group 1 helicopters that have incorporated the actions required by paragraph (2) of EASA AD 2019–0057. The FAA did not issue an AD that corresponds to EASA AD 2019–0057, therefore, this proposed AD would require, for Group 1 helicopters, an initial inspection of the torque tube assembly within 50 hours time-inservice (TIS) after the effective date of the FAA AD and repetitive inspections thereafter at intervals not to exceed 100 hours TIS. In addition, where paragraph (5) of EASA AD 2021–0096 specifies, for Group 1 helicopters, replacement of an affected part with a serviceable part ‘‘within 36 months after April 3, 2019 [the effective date of EASA AD 2019– 0057]’’, for this proposed AD, the compliance time would be within 24 months after the effective date of the FAA AD. Costs of Compliance The FAA estimates that this proposed AD affects 136 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\20JYP1.SGM 20JYP1 38244 Federal Register / Vol. 86, No. 136 / Tuesday, July 20, 2021 / Proposed Rules ESTIMATED COSTS Action Labor cost Inspection ...................... 2 work-hours × $85 per hour = $170 per inspection cycle.. 16 work-hours × $85 per hour = $1,360 ............ Replacement ................. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. khammond on DSKJM1Z7X2PROD with PROPOSALS 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Model A119 and AW119 MKII helicopters, certificated in any category, all serial numbers. (1) Where EASA AD 2021–0096 refers to flight hours (FH), this AD requires using hours time-in-service (TIS). (2) Where EASA AD 2021–0096 refers to its effective date, this AD requires using the effective date of this AD. (3) Where paragraphs (1) and (2) of EASA AD 2021–0096 specify the compliance times for Group 1 helicopters to inspect the affected part, this AD requires an initial inspection within 50 hours TIS after the effective date of this AD, and thereafter at intervals not to exceed 100 hours TIS. (4) Where paragraph (5) of EASA AD 2021– 0096 specifies, for Group 1 helicopters, replacement of an affected part with a serviceable part ‘‘within 36 months after April 3, 2019 [the effective date of EASA AD 2019–0057],’’ for this AD, that replacement must be done within 24 months after the effective date of this AD. (5) Where the service information referenced in EASA AD 2021–0096 specifies to return a torque tube assembly to the manufacturer, this AD does not include that requirement. (6) Where the service information referenced in EASA AD 2021–0096 specifies to contact the manufacturer ‘‘in case of doubt’’ regarding the batch number on a torque tube assembly, determining the batch number is required by this AD but contacting the manufacturer is not required. (7) The ‘‘Remarks’’ section of EASA AD 2021–0096 does not apply to this AD. (d) Subject (i) No Reporting Requirement Joint Aircraft Service Component (JASC) Code: 6700, Rotorcraft Flight Control Although the service information referenced in EASA AD 2021–0096 specifies to submit certain information to the manufacturer, this AD does not include that requirement. 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This 
proposed AD was prompted by reports of abnormal play on the collective 
torque tube on two Model AW119 MKII helicopters. This proposed AD would 
require repetitive inspections of affected torque tube assemblies for 
any deficiency and corrective action if necessary; and the replacement 
of any affected part with a serviceable part, which is terminating 
action for the repetitive inspections, as specified in a European Union 
Aviation Safety Agency (EASA) AD, which is proposed for incorporation 
by reference (IBR). The FAA is proposing this AD to address the unsafe 
condition on these products.

DATES: The FAA must receive comments on this proposed AD by September 
3, 2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0096, dated March 31, 2021 
(EASA AD 2021-0096), to correct an unsafe condition for Leonardo S.p.A. 
Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A., 
Agusta S.p.A.; and AgustaWestland Philadelphia Corporation, formerly 
Agusta Aerospace Corporation, Model A119 and AW119MKII helicopters, all 
serial numbers.
    This proposed AD was prompted by reports of abnormal play on the 
collective torque tube on two Model AW119 MKII helicopters. 
Investigations revealed that these events were due to an erroneous 
manufacturing process, affecting certain collective torque tube 
assemblies. The affected batch numbers were identified. Leonardo S.p.a. 
Model A119 helicopters are similar in design and may be subject to the 
same unsafe condition revealed on the Model AW119 MKII helicopters. The 
FAA is proposing this AD to address abnormal play on the collective 
torque tube, which could result in reduced control of the helicopter, 
resulting in a forced landing and consequent damage to the helicopter 
and injury to occupants. See EASA AD 2021-0096 for additional 
background information.

FAA's Determination

    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 is proposing this AD 
after evaluating all known relevant information and determining that 
the unsafe condition described previously is likely to exist or develop 
on other helicopters of these same type designs.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0096 requires repetitive inspections of the affected 
torque tube assemblies for any deficiency (i.e., any play) by marking 
the torque tube assembly and the collar and applying specific loads to 
determine if there is any play; and replacement of any affected part 
that has any play with a serviceable part. EASA AD 2021-0096 also 
requires the eventual replacement of any affected part with a 
serviceable part, and specifies that replacement of an affected part on 
a helicopter constitutes terminating action for the repetitive 
inspections for that helicopter.
    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.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2021-0096, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD and except as discussed under 
``Differences Between this Proposed AD and the EASA AD.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use certain civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0096 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance EASA AD 
2021-0096 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 EASA AD 2021-0096 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 EASA AD 2021-
0096. Service information specified in EASA AD 2021-0096 that is 
required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0572 after the FAA final rule is published.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2021-0096 supersedes EASA AD 2019-0057, dated March 20, 
2019 (EASA AD 2019-0057). The Group 1 helicopters identified in both 
EASA AD 2021-0096 and EASA AD 2019-0057 are helicopters with collective 
stick torque tube assemblies having part number (P/N) 109-0011-03-105 
and batch number 823207 or earlier. Paragraph (1) of EASA AD 2021-0096 
addresses Group 1 helicopters that have incorporated the actions 
required by paragraph (2) of EASA AD 2019-0057. The FAA did not issue 
an AD that corresponds to EASA AD 2019-0057, therefore, this proposed 
AD would require, for Group 1 helicopters, an initial inspection of the 
torque tube assembly within 50 hours time-in-service (TIS) after the 
effective date of the FAA AD and repetitive inspections thereafter at 
intervals not to exceed 100 hours TIS.
    In addition, where paragraph (5) of EASA AD 2021-0096 specifies, 
for Group 1 helicopters, replacement of an affected part with a 
serviceable part ``within 36 months after April 3, 2019 [the effective 
date of EASA AD 2019-0057]'', for this proposed AD, the compliance time 
would be within 24 months after the effective date of the FAA AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 136 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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
