Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016– PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 50849 0263–E, dated December 24, 2016 (AD 2016–0263–E), to correct an unsafe condition for Leonardo S.p.A. Helicopters (previously Agusta) Model AW189 helicopters. EASA advises that during the first scheduled maintenance of an EFS kit, float bags were found punctured. According to EASA, an investigation revealed the damage was caused by protruding parts of the pressure relief/topping valves that were not adequately protected. EASA further states that this condition could result in a partial loss of buoyancy of the EFS float bags, possibly resulting in injury to the helicopter’s occupants in a ditching event. To prevent this unsafe condition, EASA AD 2016–0263–E requires a onetime inspection of the EFS, repair of any discrepancies found, replacing the pressure relief/topping valve O-ring with a gasket, and replacing the inflate/ deflate protection with a new design inflate/deflate protection. The FAA is in the process of updating Agusta’s name change to Leonardo Helicopters on its type certificate. Because this name change is not yet effective, this proposed AD specifies Agusta. FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information We reviewed Leonardo S.p.A. Bollettino Tecnico No. 189–135, dated December 20, 2016 (BT 189–135), and Aero Sekur Service Bulletin No. SB– 189–25–003, dated November 30, 2016 (SB–189–25–003), which is attached to BT 189–135 as Annex 1. BT 189–135 specifies following the procedures in SB–189–25–003 to inspect and modify certain EFS kits installed on AW189 helicopters. Proposed AD Requirements This proposed AD would require, within 120 hours time-in-service (TIS), inspecting each float bag for punctures, replacing the pressure relief/topping (PRT) valve O-ring part number (P/N) P– G10025 with a PRT valve gasket P/N 316683A, and replacing the inflate/ deflate protection P/N 304694A with inflate/deflate protection P/N 304694B. E:\FR\FM\02NOP1.SGM 02NOP1 50850 Federal Register / Vol. 82, No. 211 / Thursday, November 2, 2017 / Proposed Rules If there are any cuts, tears, punctures, or abrasion on a float bag, the proposed AD would require repairing the float bag before further flight. Differences Between This Proposed AD and the EASA AD The EASA AD requires compliance within 15 hours TIS or 10 days for helicopters flying overwater above sea state 4 or within 120 hours or 60 days for helicopters operating overwater up to sea state 4. The proposed AD would require compliance within 120 hours TIS regardless of sea state conditions. Costs of Compliance We estimate that this proposed AD would affect two helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Inspecting each float bag, replacing the PRT valve gasket, and replacing the inflate/deflate protection would require about 40 workhours, and required parts would cost about $500, for a cost per helicopter of $3,900 and a total cost of $7,800 for the U.S. fleet. If required, repairing a float bag would require about 2 work-hours, and required parts would cost $90, for a cost per float bag of $260. nlaroche on DSK9F9SC42PROD with PROPOSALS 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. We are 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 We 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. VerDate Sep<11>2014 14:57 Nov 01, 2017 Jkt 244001 For the reasons discussed, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and 4. 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. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to determine that the Lebanon County, Pennsylvania nonattainment area (the Lebanon County Area) has attained the 2012 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS). This proposed determination of attainment, also known as a clean data determination, is based on quality assured and certified ambient air quality data for the 2014–2016 monitoring period. If finalized, the effect of this determination of attainment would be to suspend certain planning requirements for the area, including the requirement to submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures. These requirements would be suspended for as long as the area continues to meet the 2012 annual PM2.5 NAAQS. However, this proposed action is not a redesignation to attainment for the area. This action is being taken under the Clean Air Act (CAA). DATES: Written comments must be received on or before December 4, 2017.

FOR FURTHER INFORMATION CONTACT: Maria A. Pino, (215) 814–2181, or by email at pino.maria@epa.gov. SUPPLEMENTARY INFORMATION: I. Background On December 14, 2012, EPA promulgated a revised primary annual PM2.5 NAAQS to provide increased protection of public health from fine particle pollution (the 2012 PM2.5 NAAQS). See 78 FR 3086 (January 15, 2013). In that action, EPA strengthened the primary annual PM2.5 standard, lowering the level from 15.0 micrograms per cubic meter (mg/m3) to 12.0 mg/m3. The 2012 PM2.5 NAAQS is attained when the 3-year average of the annual arithmetic means does not exceed 12.0 mg/m3. See 40 CFR 50.18. On December 18, 2014 (80 FR 2206), EPA made designation determinations, as required by CAA section 107(d)(1), for the 2012 PM2.5 NAAQS. In that action, EPA designated the Lebanon County Area as moderate nonattainment for the 2012 annual PM2.5 NAAQS. See 40 CFR 81.339. Under EPA’s longstanding Clean Data Policy,1 which was codified in EPA’s Clean Air Fine Particulate Implementation Rule (72 FR 20586, April 25, 2007), EPA may issue a determination of attainment after notice and comment rulemaking determining that a specific area is attaining the relevant standard. See 40 CFR 51.1004. The effect of a clean data determination is to suspend the requirement for the 1 ‘‘Clean Data Policy for the Fine Particle National Ambient Air Quality Standards,’’ Memorandum from Stephen D. Page, December 14, 2004. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 50851 area to submit an attainment demonstration, RACM, RFP plan, contingency measures, and any other planning State Implementation Plans (SIPs) related to attainment for as long as the area continues to attain the standard. In EPA’s Fine Particulate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements (81 FR 58010, August 24, 2016), EPA reaffirmed the Clean Data Policy at 40 CFR 51.1015. The rule states that, upon a determination by EPA that a moderate PM2.5 nonattainment area has attained the PM2.5 NAAQS, the requirements for the state to submit an attainment demonstration, RACM (including reasonably available control technology (RACT) for stationary sources), RFP, quantitative milestones and quantitative milestone reports, and contingency measures for the area shall be suspended until such time as: (1) The area is redesignated to attainment, after which such requirements are permanently discharged; or, (2) EPA determines that the area has re-violated the PM2.5 NAAQS, at which time the state shall submit such attainment plan elements for the moderate nonattainment area by a future date to be determined by EPA and announced through publication in the Federal Register at the time EPA determines the area is violating the PM2.5 NAAQS. See 40 CFR 51.1015. II. EPA’s Evaluation Under EPA regulations at 40 CFR part 50, § 50.18 and appendix N, the annual primary PM2.5 standard is met when the 3-year average of PM2.5 annual mean mass concentrations for each eligible monitoring site is less than or equal to 12 mg/m3. Three years of valid annual means are required to produce a valid annual PM2.5 NAAQS design value. A year meets data completeness requirements when quarterly data capture rates for all four quarters are at least 75 percent (%) from eligible monitoring sites. See 40 CFR part 50, appendix N. By letter dated May 17, 2017, Pennsylvania certified its 2016 ambient air quality monitoring data. EPA issued final 2014–2016 design values on July 27, 2017. There is one PM2.5 monitor in the Lebanon County Area. Table 1 shows the Lebanon County Area design value for the 2012 annual PM2.5 NAAQS for the years 2014–2016 at the Lebanon County monitor. Consistent with the requirements contained in 40 CFR part 50, EPA has reviewed the PM2.5 ambient air quality monitoring data for the 2014–2016 E:\FR\FM\02NOP1.SGM 02NOP1

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2016-0263-E, dated December 24, 
2016 (AD 2016-0263-E), to correct an unsafe condition for Leonardo 
S.p.A. Helicopters (previously Agusta) Model AW189 helicopters. EASA 
advises that during the first scheduled maintenance of an EFS kit, 
float bags were found punctured. According to EASA, an investigation 
revealed the damage was caused by protruding parts of the pressure 
relief/topping valves that were not adequately protected. EASA further 
states that this condition could result in a partial loss of buoyancy 
of the EFS float bags, possibly resulting in injury to the helicopter's 
occupants in a ditching event. To prevent this unsafe condition, EASA 
AD 2016-0263-E requires a one-time inspection of the EFS, repair of any 
discrepancies found, replacing the pressure relief/topping valve O-ring 
with a gasket, and replacing the inflate/deflate protection with a new 
design inflate/deflate protection.
    The FAA is in the process of updating Agusta's name change to 
Leonardo Helicopters on its type certificate. Because this name change 
is not yet effective, this proposed AD specifies Agusta.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in its AD. We are 
proposing this AD because we evaluated all known relevant information 
and determined that an unsafe condition is likely to exist or develop 
on other products of the same type design.

Related Service Information

    We reviewed Leonardo S.p.A. Bollettino Tecnico No. 189-135, dated 
December 20, 2016 (BT 189-135), and Aero Sekur Service Bulletin No. SB-
189-25-003, dated November 30, 2016 (SB-189-25-003), which is attached 
to BT 189-135 as Annex 1. BT 189-135 specifies following the procedures 
in SB-189-25-003 to inspect and modify certain EFS kits installed on 
AW189 helicopters.

Proposed AD Requirements

    This proposed AD would require, within 120 hours time-in-service 
(TIS), inspecting each float bag for punctures, replacing the pressure 
relief/topping (PRT) valve O-ring part number (P/N) P-G10025 with a PRT 
valve gasket P/N 316683A, and replacing the inflate/deflate protection 
P/N 304694A with inflate/deflate protection P/N 304694B.

[[Page 50850]]

If there are any cuts, tears, punctures, or abrasion on a float bag, 
the proposed AD would require repairing the float bag before further 
flight.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires compliance within 15 hours TIS or 10 days for 
helicopters flying overwater above sea state 4 or within 120 hours or 
60 days for helicopters operating overwater up to sea state 4. The 
proposed AD would require compliance within 120 hours TIS regardless of 
sea state conditions.

Costs of Compliance

    We estimate that this proposed AD would affect two helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. Inspecting each float bag, replacing 
the PRT valve gasket, and replacing the inflate/deflate protection 
would require about 40 work-hours, and required parts would cost about 
$500, for a cost per helicopter of $3,900 and a total cost of $7,800 
for the U.S. fleet. If required, repairing a float bag would require 
about 2 work-hours, and required parts would cost $90, for a cost per 
float bag of $260.

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.
    We are 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

    We 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. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; and
    4. 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

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

Agusta S.p.A. Helicopters: Docket No. FAA-2017-1010; Product 
Identifier 2016-SW-089-AD.

(a) Applicability

    This AD applies to Agusta S.p.A. (Agusta) Model AW189 
helicopters, certificated in any category, with an emergency float 
system (EFS) float assembly part number (P/N) 8G9560V00131, serial 
number (S/N) 066 or lower; P/N 8G9560V00231, S/N 068 or lower; P/N 
8G9560V00331, S/N 068 or lower; or P/N 8G9560V00431, S/N 067 or 
lower, installed.

(b) Unsafe Condition

    This AD defines the unsafe condition as a punctured EFS float 
bag. This condition could result in loss of buoyancy of an EFS float 
bag being used in an emergency water ditching and subsequent injury 
to helicopter occupants.

(c) Comments Due Date

    We must receive comments by January 2, 2018.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Within 120 hours time-in-service:
    (i) Unfold and inspect each float bag assembly for any cuts, 
tears, punctures, or abrasion. If there is a cut, tear, puncture, or 
any abrasion, before further flight, repair the float bag assembly.
    (ii) Replace each O-ring P/N S-B10104 with a pressure relief/
topping (PRT) valve gasket P/N 316683A.
    (iii) Install each PRT valve P/N P-G10025 and apply a torque of 
4.5 to 5.5 Nm (39.8 to 48.6 inch-pounds).
    (iv) Replace each inflate/deflate protection P/N 304694A with a 
PRT valve protection P/N 304694B.
    (iv) Install a piece of tape approximately 220 millimeters long 
over each PRT valve protection P/N 304694B.
    (2) After the effective date of this AD, do not install an EFS 
float assembly P/N 8G9560V00131, S/N 066 or lower; P/N 8G9560V00231, 
S/N 068 or lower; P/N 8G9560V00331, S/N 068 or lower; or P/N
