SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0065, dated March 8, 2021 (EASA AD 2021– 0065), to correct an unsafe condition for certain serial-numbered Leonardo S.p.A. Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A., Model A109S and AW109SP helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Leonardo S.p.a. Model A109S and AW109SP helicopters as identified in EASA AD 2021–0065. The NPRM published in the Federal Register on September 30, 2021 (86 FR 54124). The NPRM was prompted by the discovery that rubber protection of certain electrical wiring had not been installed in the baggage avionics bay during production. The NPRM proposed to require installing protective rubber borders on the edge of the baggage avionics bay frames, as specified in EASA AD 2021–0065. The FAA is issuing this AD to prevent chafing of electrical wiring, which if not addressed, could result in fire ignition and smoke in the baggage compartment and subsequent loss of control of the helicopter. See EASA AD 2021–0065 for additional background information. E:\FR\FM\20DER1.SGM 20DER1 Federal Register / Vol. 86, No. 241 / Monday, December 20, 2021 / Rules and Regulations Discussion of Final Airworthiness Directive 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. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0065 requires installing rubber protections on the electrical wiring in the baggage/avionics compartment. 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. khammond on DSKJM1Z7X2PROD with RULES Other Related Service Information The FAA reviewed Leonardo Helicopters Alert Service Bulletin (ASB) No. 109S–100, dated February 2, 2021, for Model A109S helicopters, and Leonardo Helicopters ASB No. 109SP– 142, also dated February 2, 2021, for Model AW109SP helicopters. This service information specifies procedures for installing protective rubber borders on the edge of the baggage avionics bay frames. Costs of Compliance The FAA estimates that this AD affects 3 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Installing protective rubber borders on the edge of the baggage avionics bay frames will take about 2 work-hours and parts will cost about $24 for an estimated cost of $194 per helicopter and $582 for the U.S. fleet. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this 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 VerDate Sep<11>2014 16:01 Dec 17, 2021 Jkt 256001 rules on aviation safety.

SUPPLEMENTARY INFORMATION: Background The FAA received two reports of mechanical failure of an LCTA, the function of which is to constrain and control the non-rotating swashplate. In both failures, which occurred on Model CH–47D helicopters, the flight crew was forced to make an emergency landing as they had difficulty controlling the helicopter. Model 234 and Model CH– 47D helicopters both have the same LCTA installed, with two installed on each rotorcraft. Investigation as to the root cause of these failures has determined that inadequate maintenance overhaul procedures and scheduled overhaul intervals for this critical flight component with a single structural load path likely contributed to this unsafe condition. One event occurred due to excessive wear of the acme screw threads from degradation or lack of lubrication. The other event was due to metal fatigue leading to the fracture of the fourth stage spur gear shaft (part of the acme screw) caused by repetitive abnormal loading. The repetitive abnormal loading occurred because of the incorrect installation of a travel limit switch, which rendered the switch ineffective in removing power from the electric motor at the designed travel limit, thus allowing the electric motor to repetitively overstroke the actuator into a mechanical stop. While the failure modes were different, the failure effects were the same: Loss of the constraint and control normally provided by the LCTA. Failure of the LCTA, if not prevented, could result in loss of control of the rotor blades and subsequent loss of control of the helicopter or the rotor blades striking the fuselage. The FAA is issuing this AD to address the unsafe condition on these products. The type certificate (TC) holder for Model 234 helicopters is Columbia Helicopters Inc. (TC previously held by Boeing Defense & Space Group), and the TC holders for Model CH–47D helicopters currently include Columbia Helicopters, Inc., Billings Flying Service, Inc., Tandem Rotor, LLC, and Unical Aviation, Inc.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0065, dated March 8, 2021 (EASA 
AD 2021-0065), to correct an unsafe condition for certain serial-
numbered Leonardo S.p.A. Helicopters, formerly Finmeccanica S.p.A., 
AgustaWestland S.p.A., Agusta S.p.A., Model A109S and AW109SP 
helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Leonardo S.p.a. Model 
A109S and AW109SP helicopters as identified in EASA AD 2021-0065. The 
NPRM published in the Federal Register on September 30, 2021 (86 FR 
54124). The NPRM was prompted by the discovery that rubber protection 
of certain electrical wiring had not been installed in the baggage 
avionics bay during production. The NPRM proposed to require installing 
protective rubber borders on the edge of the baggage avionics bay 
frames, as specified in EASA AD 2021-0065.
    The FAA is issuing this AD to prevent chafing of electrical wiring, 
which if not addressed, could result in fire ignition and smoke in the 
baggage compartment and subsequent loss of control of the helicopter. 
See EASA AD 2021-0065 for additional background information.

[[Page 71819]]

Discussion of Final Airworthiness Directive

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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0065 requires installing rubber protections on the 
electrical wiring in the baggage/avionics compartment.
    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.

Other Related Service Information

    The FAA reviewed Leonardo Helicopters Alert Service Bulletin (ASB) 
No. 109S-100, dated February 2, 2021, for Model A109S helicopters, and 
Leonardo Helicopters ASB No. 109SP-142, also dated February 2, 2021, 
for Model AW109SP helicopters. This service information specifies 
procedures for installing protective rubber borders on the edge of the 
baggage avionics bay frames.

Costs of Compliance

    The FAA estimates that this AD affects 3 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Installing protective rubber borders on the edge of the baggage 
avionics bay frames will take about 2 work-hours and parts will cost 
about $24 for an estimated cost of $194 per helicopter and $582 for the 
U.S. fleet.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 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

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

2021-25-01 Leonardo S.p.a.: Amendment 39-21844; Docket No. FAA-2021-
0834; Project Identifier MCAI-2021-00298-R.

(a) Effective Date

    This airworthiness directive (AD) is effective January 24, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Leonardo S.p.a. Model A109S and AW109SP 
helicopters, certificated in any category, as identified in European 
Union Aviation Safety Agency (EASA) AD 2021-0065, dated March 8, 
2021 (EASA AD 2021-0065).

(d) Subject

    Joint Aircraft Service Component (JASC) Code: 2497, Electrical 
Power System Wiring.

(e) Unsafe Condition

    This AD was prompted by the discovery that rubber protection of 
certain electrical wiring had not been installed in the baggage 
avionics bay during production. The FAA is issuing this AD to 
prevent chafing of electrical wiring. The unsafe condition, if not 
addressed, could result in fire ignition and smoke in the baggage 
compartment 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, EASA AD 2021-0065.

(h) Exceptions to EASA AD 2021-0065

    (1) Where EASA AD 2021-0065 requires compliance in terms of 
flight hours, this AD requires using hours time-in-service.
    (2) Where EASA AD 2021-0065 refers to its effective date, this 
AD requires using the effective date of this AD.
    (3) This AD does not mandate compliance with the ``Remarks'' 
section of EASA AD 2021-0065.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2021-0065 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Special Flight Permit

    Special flight permits are prohibited.

(k) 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, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the International Validation Branch, send 
it to the attention of the person identified in paragraph (l) of 
this AD. Information may be emailed to: [email protected].
