Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2019– 0172, dated July 18, 2019, to correct an unsafe condition for Airbus Helicopters (formerly Eurocopter, Eurocopter France, Aerospatiale) Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters with M/R hub part number 332A31–0001–00, P/N 332A31–0001– 01, P/N 332A31–0001–02, P/N 332A31– 0001–03, P/N 332A31–0001–04, P/N 332A31–0001–05, or P/N 332A31– 0001–06 installed. EASA advises of reported occurrences of ‘‘NR’’ sensor fluctuation and subsequent investigation identifying incorrect positioning of the M/R hub phonic wheel due to incorrect installation of the M/R mast nut press screws during maintenance of the M/R hubs. The investigation also determined that this incorrect installation can be identified by inspecting the lock washer position. EASA advises that this condition, if not detected and corrected, could lead to failure of M/R hub components, possibly resulting in loss of helicopter control. Accordingly, the EASA AD requires a one-time inspection of the lock washer position and depending on findings, replacing the M/R hub. 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 VerDate Sep<11>2014 17:19 Jul 15, 2020 Jkt 250001 determining that an unsafe condition is likely to exist or develop on other helicopters of the same type designs. Related Service Information Under 1 CFR Part 51 The FAA reviewed Airbus Helicopters Alert Service Bulletin No. AS332– 62.00.76, Revision 0, dated May 27, 2019, for civilian Model AS332C, C1, L, and L1 and military Model AS332B, B1, F1, M, and M1 helicopters. This service information specifies inspecting the position of the M/R hub lock washer. 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. Proposed AD Requirements This proposed AD would require, within 55 hours time-in-service, removing at least one ‘‘NR’’ sensor and borescope inspecting for the correct height of the lock washer through the hole of the removed ‘‘NR’’ sensor. This proposed AD would then require installing an ‘‘NR’’ sensor(s), and if the lock washer height is not correct, also repairing or replacing the M/R hub with an airworthy M/R hub. This proposed AD would also prohibit the installation of an affected M/R hub unless it has successfully passed the required inspection for correct lock washer installation. Differences Between This Proposed AD and the EASA AD The EASA AD requires using a flashlight and visually inspecting the position of the lock washer, and further specifies that using an endoscope can facilitate that inspection. This proposed AD would require borescope inspecting for the correct height of the lock washer instead. After inspecting, the EASA AD requires reinstalling the removed ‘‘NR’’ sensor(s), while this proposed AD would require installing airworthy ‘‘NR’’ sensor(s) instead. If the lock washer is in an incorrect position, the EASA AD requires replacing the M/R hub, whereas this proposed AD would require repairing or replacing the M/R hub with an airworthy M/R hub instead. Costs of Compliance The FAA estimates that this proposed AD affects 11 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this proposed AD. Removing an ‘‘NR’’ sensor and borescope inspecting would take about PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 43161 0.5 work-hour for an estimated cost of $43 per helicopter and $473 for the U.S. fleet. Repairing the M/R hub would take about 10 work-hours and parts would cost up to about $3,000 for an estimated cost of up to $3,850 and replacing the M/R hub would take about 8 work-hours and parts would cost about $50,000 for an estimated cost of $50,680. 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, 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.

SUPPLEMENTARY INFORMATION: I. Background Since at least 1940,1 the Commission has pursued enforcement actions to prevent unfair and deceptive ‘‘Made in USA’’ and other U.S.-origin claims (‘‘MUSA claims’’). Currently, the Commission’s comprehensive MUSA program consists of compliance monitoring, counseling, and targeted enforcement pursuant to the FTC’s general authority under Section 5 of the FTC Act, 15 U.S.C. 45.2 However, Congress has also granted the FTC authority to address MUSA labeling, including rulemaking authority, under a separate statute, 15 U.S.C. 45a.3 To date, the Commission has not exercised its rulemaking authority under that provision. Recently, the FTC held a public workshop and collected public comments in support of a review of its 1 See, e.g., Vulcan Lamp Works, Inc., 32 F.T.C. 7 (1940). 2 Section 5 prohibits unfair or deceptive acts or practices in or affecting commerce. An act or practice is deceptive if it is likely to mislead consumers acting reasonably under the circumstances and is material—that is, likely to affect a consumer’s decision to purchase or use the advertised product or service. A claim need not mislead all—or even most—consumers to be deceptive under the FTC Act. Rather, it need only be likely to deceive some consumers acting reasonably. See FTC Policy Statement on Deception, 103 F.T.C. 174 (1984) (appended to Cliffdale Assocs., Inc., 103 F.T.C. 110, 177 n.20 (1984) (‘‘A material practice that misleads a significant minority of reasonable consumers is deceptive.’’); see also FTC v. Stefanchik, 559 F.3d 924, 929 (9th Cir. 2009) (‘‘The FTC was not required to show that all consumers were deceived . . . .’’). 3 See Section 320933 of the Violent Crime and Law Enforcement Act of 1994, Public Law 103–322, 108 Stat. 1796, codified in relevant part at 15 U.S.C. 45a. Under the statute, the Commission may issue a rule pursuant to 5 U.S.C. 553. Section 45a also states that: ‘‘This section shall be effective upon publication in the Federal Register of a Notice of the provisions of this section.’’ The Commission published such a notice in 1995 (60 FR 13158 (Mar. 10, 1995)).

Airworthiness Directives; Airbus 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 Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 
helicopters. This proposed AD would require inspecting the main rotor 
(M/R) hub assembly (hub) phonic wheel lock washer (lock washer) for

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2019-0172, dated July 18, 2019, 
to correct an unsafe condition for Airbus Helicopters (formerly 
Eurocopter, Eurocopter France, Aerospatiale) Model AS 332 C, AS 332 C1, 
AS 332 L, and AS 332 L1 helicopters with M/R hub part number 332A31-
0001-00, P/N 332A31-0001-01, P/N 332A31-0001-02, P/N 332A31-0001-03, P/
N 332A31-0001-04, P/N 332A31-0001-05, or P/N 332A31-0001-06 installed. 
EASA advises of reported occurrences of ``NR'' sensor fluctuation and 
subsequent investigation identifying incorrect positioning of the M/R 
hub phonic wheel due to incorrect installation of the M/R mast nut 
press screws during maintenance of the M/R hubs. The investigation also 
determined that this incorrect installation can be identified by 
inspecting the lock washer position. EASA advises that this condition, 
if not detected and corrected, could lead to failure of M/R hub 
components, possibly resulting in loss of helicopter control.
    Accordingly, the EASA AD requires a one-time inspection of the lock 
washer position and depending on findings, replacing the M/R hub.

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 an 
unsafe condition is likely to exist or develop on other helicopters of 
the same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Airbus Helicopters Alert Service Bulletin No. 
AS332-62.00.76, Revision 0, dated May 27, 2019, for civilian Model 
AS332C, C1, L, and L1 and military Model AS332B, B1, F1, M, and M1 
helicopters. This service information specifies inspecting the position 
of the M/R hub lock washer.
    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.

Proposed AD Requirements

    This proposed AD would require, within 55 hours time-in-service, 
removing at least one ``NR'' sensor and borescope inspecting for the 
correct height of the lock washer through the hole of the removed 
``NR'' sensor. This proposed AD would then require installing an ``NR'' 
sensor(s), and if the lock washer height is not correct, also repairing 
or replacing the M/R hub with an airworthy M/R hub.
    This proposed AD would also prohibit the installation of an 
affected M/R hub unless it has successfully passed the required 
inspection for correct lock washer installation.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires using a flashlight and visually inspecting the 
position of the lock washer, and further specifies that using an 
endoscope can facilitate that inspection. This proposed AD would 
require borescope inspecting for the correct height of the lock washer 
instead. After inspecting, the EASA AD requires reinstalling the 
removed ``NR'' sensor(s), while this proposed AD would require 
installing airworthy ``NR'' sensor(s) instead. If the lock washer is in 
an incorrect position, the EASA AD requires replacing the M/R hub, 
whereas this proposed AD would require repairing or replacing the M/R 
hub with an airworthy M/R hub instead.

Costs of Compliance

    The FAA estimates that this proposed AD affects 11 helicopters of 
U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates that operators may incur the following 
costs in order to comply with this proposed AD.
    Removing an ``NR'' sensor and borescope inspecting would take about 
0.5 work-hour for an estimated cost of $43 per helicopter and $473 for 
the U.S. fleet.
    Repairing the M/R hub would take about 10 work-hours and parts 
would cost up to about $3,000 for an estimated cost of up to $3,850 and 
replacing the M/R hub would take about 8 work-hours and parts would 
cost about $50,000 for an estimated cost of $50,680.

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, 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.
