Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2019-1003; Product Identifier 2018-SW-086-AD; Amendment 
39-21294; AD 2020-21-21]
RIN 2120-AA64


Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Leonardo S.p.a. (Leonardo) Model A109E, A109S, A119, AW109SP, and 
AW119MKII helicopters. This AD requires removing certain main rotor (M/
R) floating ring assemblies from service. This AD also prohibits 
replacing any washer on any M/R floating ring assembly. This AD was 
prompted by a report of a washer debonding from the M/R floating ring 
assembly. The actions of this AD are intended to address an unsafe 
condition on these products.

DATES: This AD is effective November 24, 2020.

ADDRESSES: For service information identified in this final rule, 
contact Leonardo S.p.a. Helicopters, Emanuele Bufano, Head of 
Airworthiness, Viale G. Agusta 520, 21017 C. Costa di Samarate (Va) 
Italy; telephone +39-0331-225074; fax +39-0331-229046; or at https://www.leonardocompany.com/en/home. You may view the referenced service

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 Leonardo Model A109E, 
A109S, A119, AW109SP, and AW119MKII helicopters, with a M/R floating 
ring assembly part number (P/N) 109-0111-09-101 or P/N 109-0111-09-103 
installed. The NPRM published in the Federal Register on December 9, 
2019 (84 FR 67251). The NPRM proposed to require removing from service 
any M/R floating ring assembly P/N 109-0111-09-101 or P/N 109-0111-09-
103 with serial number (S/N) DA53295148-1, F86782, G130924, J31213, 
L99, L104, L107, L117, L127, L130, M215, P411, R687, R735, R769, R772, 
or V71. The NPRM also proposed to prohibit installing the affected M/R 
floating ring assemblies on any helicopter. Lastly, the NPRM proposed 
to prohibit replacing any washer P/N 109-0111-23-101 on any M/R 
floating ring assembly installed on any helicopter. The proposed 
requirements were intended to prevent failure of the M/R floating ring 
assembly and significant increase of the pilot workload and subsequent 
loss of control of the helicopter.
    The NPRM was prompted by EASA AD No. 2018-0205, dated September 14, 
2018, 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. (formerly Finmeccanica S.p.A., AgustaWestland S.p.A., 
Agusta S.p.A.; and AgustaWestland Philadelphia Corporation, formerly 
Agusta Aerospace Corporation) Model A109E, A109S, A119, A109LUH, 
AW109SP, and AW119MKII helicopters with certain part-numbered M/R 
floating ring assemblies installed. EASA advises of a report of a 
washer P/N 109-0111-23-101 that debonded from the M/R floating ring 
assembly on a Model A109E helicopter. Investigation results revealed 
that the M/R floating ring assembly had been improperly repaired, and 
identified a batch of M/R floating ring assemblies that could also be 
affected. Due to design similarity, some of those M/R floating ring 
assemblies may be installed on other A109/A119 helicopter models.
    EASA further advises that this condition, if not detected and 
corrected, could lead to failure of an affected M/R floating ring 
assembly and significant increase of the pilot workload, possibly 
resulting in reduced control of the helicopter. Accordingly, the EASA 
AD requires inspecting the M/R floating ring assembly to identify its 
S/N and depending on findings, replacing affected serial-numbered M/R 
floating ring assemblies. The EASA AD also prohibits installing those 
serial-numbered M/R floating ring assemblies on any helicopter and 
prohibits replacing washer P/N 109-0111-23-101 on an M/R floating ring 
assembly installed on a helicopter.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule, but the FAA did not receive any comments on 
the NPRM or on the determination of the cost to the public.

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 of the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all of the information provided by EASA and determining the 
unsafe condition exists and is likely to exist or develop on other 
helicopters of these same type designs and that air safety and the 
public interest require

[[Page 66470]]

adopting the AD requirements as proposed.

Differences Between This AD and the EASA AD

    The EASA AD applies to Model A109LUH helicopters, whereas this AD 
does not because that model is not FAA type-certificated.

Related Service Information

    The FAA reviewed Leonardo Helicopters Alert Service Bulletin (ASB) 
No. 109EP-163 for Model A109E helicopters; ASB No. 109S-084 for Model 
A109S helicopters; ASB No. 109SP-125 for Model AW109SP helicopters; and 
ASB No. 119-092 for Model A119 and AW119MKll helicopters, all Revision 
A and dated September 13, 2018. This service information contains 
procedures to identify the S/N of the M/R floating ring assembly and 
provides instructions for replacing the floating ring assembly if 
necessary. This service information also specifies replacing certain 
serial-numbered M/R floating ring assemblies and reporting certain 
information to Leonardo Helicopters.

Costs of Compliance

    The FAA estimates that this AD affects 210 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 M/R floating ring assembly takes about 1 work-hour 
for an estimated cost of $85 per helicopter and $17,850 for the U.S. 
fleet. Replacing an M/R floating ring assembly takes about 8 work-hours 
and parts cost about $5,500 for an estimated cost of $6,180 per 
floating ring assembly.
    According to Leonardo Helicopters, some of the costs of this AD may 
be covered under warranty, thereby reducing the cost impact on affected 
individuals. The FAA does not control warranty coverage by Leonardo 
Helicopters. Accordingly, the FAA has included all costs in the 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 helicopters 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.
