C. Issues on Which DOE Seeks Comment Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues: 1. DOE seeks comment on its assumptions that only minor changes to the DHE market have occurred since the last DOE rulemaking and that overall shipments of DHE have continued to decrease. See section II. 2. DOE seeks comment on its determination that adopting a condensing efficiency level for fan-type wall furnaces would not be economically justified. See section II. 3. DOE seeks data and information pertaining to DHE shipments. See section II. 4. DOE seeks comment on its proposal not to amend energy conservation standards for DHE because more stringent standards would not be economically justified. See section III. 5. DOE seeks comment on its proposal not to amend its standards for DHE to include standby and off mode electrical consumption. See section III. jstallworth on DSK7TPTVN1PROD with PROPOSALS VI. Approval of the Office of the Secretary The Secretary of Energy has approved publication of this notice of proposed rulemaking.

Discussion EASA, which is the Technical Agent for the Member States of the European E:\FR\FM\11APP1.SGM 11APP1 Federal Register / Vol. 81, No. 69 / Monday, April 11, 2016 / Proposed Rules Union, has issued EASA AD No. 2015– 0094, dated May 29, 2015, to correct an unsafe condition for Airbus Helicopters Model AS350B, AS350BA, AS350BB, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, EC130B4, and EC130T2 helicopters. EASA advises that two cases of cracks in a cross-bar were reported on AS350B3 helicopters. The cracks were found at the transmission deck attachment fitting holes during a maintenance check, EASA states. According to EASA, in both cases, the helicopters were equipped with a cargo hook and had completed missions with a significant number of torque cycles. Because of common design features, cracks may also occur on other Model AS350-series, AS355-series, and EC130series helicopters. EASA advises that crack growth may lead to failure of one of the four yokes and significantly increased stress load on the remaining yokes. This condition, if not detected or corrected, could lead to cracks on the remaining yokes and increased load on the cross-bar, possibly resulting in cross-bar failure and consequently loss of the helicopter. To correct this condition, EASA AD No. 2015–0094 requires repetitive cross-bar inspections and, depending on the findings, replacing the cross-bar. jstallworth on DSK7TPTVN1PROD with PROPOSALS FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, 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 Airbus Helicopters has issued Alert Service Bulletin (ASB) No. EC130– 05A021 for Model EC130B4 helicopters; ASB No. EC130–05A022 for Model EC130T2 helicopters; ASB No. AS350– 05.00.84 for Model AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350BB, AS350D, and military Model AS350L1 helicopters; and ASB No. 355– 05.00.73 for Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355 NP helicopters (ASBs). All of the ASBs are Revision 0 and dated May 21, 2015. The ASBs specify visually inspecting the cross-bar. If there is any doubt after the visual inspection, the ASBs call for a dye-penetrant inspection to make sure there are no cracks. If a VerDate Sep<11>2014 14:15 Apr 08, 2016 Jkt 238001 crack is detected, the ASBs call for replacing the cross-bar before further flight and sending the damaged crossbar to Airbus Helicopters. Proposed AD Requirements This proposed AD would require, within certain initial inspection times or the next time any maintenance of the helicopter involves removing the main gearbox, whichever comes first, inspecting each cross-bar for a crack. If there is a crack, this proposed AD would require replacing the cross-bar before further flight. This proposed AD would also require repeating these inspections at the same intervals as the initial inspection. The compliance times in this proposed AD include torque cycles, which are defined for purposes of this AD, as one landing with or without stopping the rotor or one external load-carrying operation. An external load-carrying operation occurs each time a helicopter picks up an external load and drops it off. Differences Between This Proposed AD and the EASA AD The EASA AD applies to Airbus Helicopters Model AS350BB helicopters. This proposed AD would not apply to the Model AS350BB because it has no FAA type certificate. However, this proposed AD would apply to Model AS350C and AS350D1 helicopters, while the EASA AD does not. The EASA AD requires a florescent dye-penetrant inspection if the visual inspection of the bi-directional suspension cross-bar causes doubts. This proposed AD would not require a florescent dye-penetrant inspection. The EASA AD requires returning the damaged bi-directional suspension cross-bar to Airbus Helicopters, and this proposed AD would not. Costs of Compliance We estimate that this proposed AD would affect 1,132 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: • Visually inspecting the cross-bar would require 16.5 work-hours for a labor cost of about $1,403. No parts would be needed so that the cost for the U.S. fleet would total $1,588,196 per inspection cycle. • Replacing the cross-bar would cost $1,630 for parts. No additional labor costs would be needed. 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 PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 21285 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.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European

[[Page 21285]]

Union, has issued EASA AD No. 2015-0094, dated May 29, 2015, to correct 
an unsafe condition for Airbus Helicopters Model AS350B, AS350BA, 
AS350BB, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, 
AS355F2, AS355N, AS355NP, EC130B4, and EC130T2 helicopters. EASA 
advises that two cases of cracks in a cross-bar were reported on 
AS350B3 helicopters. The cracks were found at the transmission deck 
attachment fitting holes during a maintenance check, EASA states. 
According to EASA, in both cases, the helicopters were equipped with a 
cargo hook and had completed missions with a significant number of 
torque cycles. Because of common design features, cracks may also occur 
on other Model AS350-series, AS355-series, and EC130-series 
helicopters. EASA advises that crack growth may lead to failure of one 
of the four yokes and significantly increased stress load on the 
remaining yokes. This condition, if not detected or corrected, could 
lead to cracks on the remaining yokes and increased load on the cross-
bar, possibly resulting in cross-bar failure and consequently loss of 
the helicopter. To correct this condition, EASA AD No. 2015-0094 
requires repetitive cross-bar inspections and, depending on the 
findings, replacing the cross-bar.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, 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

    Airbus Helicopters has issued Alert Service Bulletin (ASB) No. 
EC130-05A021 for Model EC130B4 helicopters; ASB No. EC130-05A022 for 
Model EC130T2 helicopters; ASB No. AS350-05.00.84 for Model AS350B, 
AS350B1, AS350B2, AS350B3, AS350BA, AS350BB, AS350D, and military Model 
AS350L1 helicopters; and ASB No. 355-05.00.73 for Model AS355E, AS355F, 
AS355F1, AS355F2, AS355N, and AS355 NP helicopters (ASBs). All of the 
ASBs are Revision 0 and dated May 21, 2015. The ASBs specify visually 
inspecting the cross-bar. If there is any doubt after the visual 
inspection, the ASBs call for a dye-penetrant inspection to make sure 
there are no cracks. If a crack is detected, the ASBs call for 
replacing the cross-bar before further flight and sending the damaged 
cross-bar to Airbus Helicopters.

Proposed AD Requirements

    This proposed AD would require, within certain initial inspection 
times or the next time any maintenance of the helicopter involves 
removing the main gearbox, whichever comes first, inspecting each 
cross-bar for a crack. If there is a crack, this proposed AD would 
require replacing the cross-bar before further flight. This proposed AD 
would also require repeating these inspections at the same intervals as 
the initial inspection. The compliance times in this proposed AD 
include torque cycles, which are defined for purposes of this AD, as 
one landing with or without stopping the rotor or one external load-
carrying operation. An external load-carrying operation occurs each 
time a helicopter picks up an external load and drops it off.

Differences Between This Proposed AD and the EASA AD

    The EASA AD applies to Airbus Helicopters Model AS350BB 
helicopters. This proposed AD would not apply to the Model AS350BB 
because it has no FAA type certificate. However, this proposed AD would 
apply to Model AS350C and AS350D1 helicopters, while the EASA AD does 
not. The EASA AD requires a florescent dye-penetrant inspection if the 
visual inspection of the bi-directional suspension cross-bar causes 
doubts. This proposed AD would not require a florescent dye-penetrant 
inspection. The EASA AD requires returning the damaged bi-directional 
suspension cross-bar to Airbus Helicopters, and this proposed AD would 
not.

Costs of Compliance

    We estimate that this proposed AD would affect 1,132 helicopters of 
U.S. Registry and that labor costs average $85 a work-hour. Based on 
these estimates, we expect the following costs:
     Visually inspecting the cross-bar would require 16.5 work-
hours for a labor cost of about $1,403. No parts would be needed so 
that the cost for the U.S. fleet would total $1,588,196 per inspection 
cycle.
     Replacing the cross-bar would cost $1,630 for parts. No 
additional labor costs would be needed.

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):

Airbus Helicopters: Docket No. FAA-2015-3929; Directorate Identifier 
2015-SW-031-AD.

(a) Applicability

    This AD applies to Airbus Helicopters Model EC130B4, EC130T2, 
AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, AS350D1, 
AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters 
with a bi-directional suspension cross-bar (cross-bar) part number 
(P/N) 350A38-1040-20 or P/N 350A38-1040-00 installed, certificated 
in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as a crack in a bi-
directional cross-bar, which could result in failure of a cross-bar 
and loss of control of the helicopter.

(c) Comments Due Date

    We must receive comments by June 10, 2016

(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 the initial inspection times shown in Table 1 to 
paragraph (e) of this AD or the next time maintenance of the 
helicopter involves removing the main gearbox, whichever comes 
first; and thereafter at intervals not to exceed the compliance 
times shown in Table 1 to paragraph (e) of this AD, inspect each 
cross-bar for a crack. For purposes of this AD, a torque cycle is 
defined as one landing with or without stopping the rotor or one 
external load-carrying operation; an external load-carrying 
operation occurs each time a helicopter picks up an external load 
and drops it off.
