14 CFR Part 39

[Docket No. FAA-2020-0468; Product Identifier 2018-SW-046-AD]
RIN 2120-AA64


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 that certain fuel control units 
(FCU) may not have been calibrated to specification during overhaul. 
This proposed AD would require revising the rotorcraft flight manual 
(RFM) for your helicopter and installing a placard to prohibit 
intentional entry into autorotation. This proposed AD would also allow 
replacement of an affected FCU as an optional terminating action for 
the RFM revision and placard installation. 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 July 27, 
2020.

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

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, issued EASA AD 2018-0124, dated June 5, 2018 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Leonardo S.p.A. 
Model A119 and AW119 MKII helicopters. EASA advises that certain FCUs 
may not have been calibrated to specification during overhaul, and that 
this condition, if not corrected, can lead to N1 fluctuations, hung 
engine starts, and the inability to recover power during autorotation 
training, possibly resulting in reduced control of the helicopter. To 
address this unsafe condition, the EASA AD requires amendment of the 
applicable RFM and installation of a placard to prohibit intentional 
entry into autorotation. The EASA AD also allows removal of the RFM 
limitation and placard after replacement of an affected FCU.
    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-2020-0468.

Related Service Information Under 1 CFR Part 51

    Leonardo S.p.A. has issued Leonardo Helicopters Emergency Alert 
Service Bulletin 119-089, Revision A, dated June 5, 2018. This service 
information describes procedures for revising the RFM and installing a 
placard in the cockpit.
    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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is proposing this AD 
after evaluating all the relevant information and determining the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

[[Page 35603]]

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Interim Action

    The FAA considers this proposed AD interim action. If final action 
is later identified, the FAA might consider further rulemaking.

Costs of Compliance

    The FAA estimates that this proposed AD affects 64 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...........................             $50             $220          $14,080
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable it to 
provide cost estimates for the optional terminating action specified in 
this proposed AD.

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) 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.
